Action continues to fall far short of pledges, even as temperature and greenhouse gas records are repeatedly broken

Catherine Early

( China Dialogue ) – Countries must make far greater efforts to implement their climate strategies this decade to stand a chance of keeping global temperature rise within 1.5C (2.7F) of the pre-industrial average.

Continued delays will only increase the world’s reliance on uncertain carbon dioxide removal technologies (CDR), according to the UN Environment Programme (UNEP).

In the most recent annual assessment of progress on global climate action, the Emissions Gap Report 2023, UNEP pointed to progress since the Paris Agreement. When it was adopted in 2015, greenhouse gas emissions were projected to rise 16% by 2030. Today, that increase is projected to be 3%.

But from now emissions must fall 28% by 2030 to keep temperature rise to 3.6F (2C), or 42% to stay within 2.7F (1.5C), and countries are failing to match this need with action, UNEP found.

Current climate policies will result in a rise of 3C this century. The increase will be limited to 5.2F (2.9C) if countries fully implement their national climate plans (known as Nationally Determined Contributions, or NDCs).

This could be kept to 4.5F (2.5C) if plans by developing countries, which are currently conditional on obtaining financial support, are carried out – since that would result in a 9% fall in emissions.  

In UNEP’s most optimistic scenario, where all conditional NDCs and net zero pledges are met, limiting temperature rise to 3.6F (2C) could be achieved, UNEP says. This scenario is considered to give at best a 14% chance of limiting warming to 2.7F (1.5C).

Now, 97 countries have pledged to meet net zero emissions, up from 88 last year. Pledges cover 81% of the world’s greenhouse gases (GHGs). However, the authors do not consider these pledges to be credible, pointing out that none of the G20 countries are reducing emissions at a pace consistent with their net-zero targets.

National net zero plans have several flaws, according to Anne Olhoff, chief scientific editor of the report. Many are not legally binding, or fail to have clear implementation plans, and there is a lack of targets between now and the dates when governments claim to be aiming for net zero, she says.

“But most importantly, emissions are still going up in countries that have put forward zero emission pledges. There are many ways to net zero, but at some point you need to peak and reduce. And the longer you wait until you peak, the more difficult it’s likely to be to actually get to net zero,” she says.

Under the Paris Agreement, ambition in the NDCs is designed to be ramped up over time. At COP28, which begins in Dubai at the end of November, countries will debate how to build new ambition under the first Global Stocktake. This will inform the next round of NDCs that countries should submit in 2025, which will have targets for 2035.

Countries should focus on implementing existing policies this decade, rather than pledging higher targets for 2030, says Olhoff.

“Whether or not the ambition of the 2030 targets is raised or not is less important than achieving those targets. If countries find that they can also strengthen ambition for 2030, that’s an added benefit,” she says.

The more action taken this decade, the more ambitious countries can be in their new targets for 2035, and the easier it will be to achieve those targets, she points out.

The report states that high-income and high-emitting countries among the G20 should take the most ambitious and rapid action, and provide financial and technical support to developing nations.

However, it adds that low- and middle-income countries already account for more than two-thirds of global greenhouse gas emissions. Development needs in these countries need to be met with economic growth that produces low emissions, such as by reducing energy demand and prioritising clean energy, it says.

“This is an extremely large and diverse group of countries, and the opportunities for low-emissions growth depend a lot on national circumstances,” Ohloff says. Proposed reforms to international finance through multilateral development banks should improve access to finance and the ability of developing countries to attract investment. Borrowing often costs a lot more in these countries than in developed ones, she says. 

But some countries who suffer from corruption need to “get their own house in order” and improve governance to avoid this, she adds.

The role of carbon removal

The report points out that the world will also need to use carbon dioxide removal (CDR), which the authors see as having a role on three timescales.

It can already contribute to lowering net emissions, today.

In the medium term, it can contribute to tackling residual emissions from so-called hard-to-abate sectors, such as aviation and heavy industry.

And in the longer term, CDR could potentially be deployed at a large enough scale to bring about a decline in the global mean temperature. They stress that its use should be in addition to rapid decarbonisation of industry, transport, heat and power systems.

CDR refers to the direct removal of CO2 from the atmosphere and its durable storage in geological, terrestrial or ocean reservoirs, or in products. It is different to carbon capture and storage (CSS), which captures CO2 from emissions at their sources, such as a power station, and transfers it into permanent storage. While some CCS methods share features with CDR, they can never result in CO2 removal from the atmosphere.

Some CDR is already being deployed, mainly through reforestation, afforestation and forest management. However, this is very small scale, with removals estimated at 2 gigatonnes of carbon dioxide equivalent (GtCO2e) annually. Research and development into more novel technologies is increasing, with methods including sequestering carbon in soil; enhanced weathering, which speeds up the natural weathering of rocks to store CO2; and direct air capture and storage (DACC), where CO2 is extracted from the atmosphere.

There are multiple risks associated with scaling up CDR. These include competition with land for food, protection of tenure and rights, as well as public perception. In addition, the technical, economic and political requirements for large-scale deployment may not materialise in time, UNEP says. Some methods are very expensive, particularly DACC, which UNEP estimates at US$800 per tonne of CO2 removed.

Governments have tended not to specify the extent to which they plan to use CDR to achieve their emission-reduction targets, nor the residual emissions they plan to allow annually when achieving net-zero CO2 and greenhouse gas emission targets, UNEP found. Estimates of the implied levels of land-based removals in long-term strategies and net-zero pledges are 2.1-2.9 GtCO2 of removals per year by 2050, though this is based on an incomplete sample of 53 countries, the report notes.

Politicians need to coordinate the development of CDR, the report states. Dr Oliver Geden, lead author of the chapter on CDR, explains that governments need to clarify their role in national and global climate policy, and develop standards for measuring, reporting and verifying emissions reductions that can eventually be included in national GHG inventories under the UN climate change process.

National weather analysts released their 2023 billion-dollar disasters list on Jan. 9, just as 2024 was getting off to a ferocious start. A blizzard was sweeping across across the Plains and Midwest, and the South and East faced flood risks from extreme downpours.

The U.S. set an unwelcome record for weather and climate disasters in 2023, with 28 disasters that exceeded more than US$1 billion in damage each.

While it wasn’t the most expensive year overall – the costliest years included multiple hurricane strikes – it had the highest number of billion-dollar storms, floods, droughts and fires of any year since counting began in 1980, with six more than any other year, accounting for inflation.

The year’s most expensive disaster started with an unprecedented heat wave that sat over Texas for weeks over the summer and then spread into the South and Midwest, helping fuel a destructive drought. The extreme heat and lack of rain dried up fields, forced ranchers to sell off livestock and restricted commerce on the Mississippi River, causing about US$14.5 billion in damage, according to the National Oceanic and Atmospheric Administration’s conservative estimates.

Extreme dryness in Hawaii contributed to another multi-billion-dollar disaster as it fueled devastating wildfires that destroyed Lahaina, Hawaii, in August.

Other billion-dollar disasters included Hurricane Idalia, which hit Florida in August; floods in the Northeast and California; and nearly two dozen other severe storms across the country. States in a swath from Texas to Ohio were hit by multiple billion-dollar storms.

NBC News: “New details of the devastating Lahaina wildfire that killed over 100 people”

El Niño played a role in some of these disasters, but at the root of the world’s increasingly frequent extreme heat and weather is global warming. The year 2023 was the hottest on record globally and the fifth warmest in the U.S.

I am an atmospheric scientist who studies the changing climate. Here’s a quick look at what global warming has to do with wildfires, storms and other weather and climate disasters.

Dangerous heat waves and devastating wildfires

When greenhouse gases, such as carbon dioxide from vehicles and power plants, accumulate in the atmosphere, they act like a thermal blanket that warms the planet.

These gases let in high-energy solar radiation while absorbing outgoing low-energy radiation in the form of heat from the Earth. The energy imbalance at the Earth’s surface gradually increases the surface temperature of the land and oceans.

The most direct consequence of this warming is more days with abnormally high temperatures, as large parts of the country saw in 2023.

Phoenix went 30 days with daily high temperatures at 110 F (43.3 C) or higher and recorded its highest minimum nighttime temperature, with temperatures on July 19 never falling below 97 F (36.1 C).

Although heat waves result from weather fluctuations, global warming has raised the baseline, making heat waves more frequent, more intense and longer-lasting.

That heat also fuels wildfires.

Increased evaporation removes more moisture from the ground, drying out soil, grasses and other organic material, which creates favorable conditions for wildfires. All it takes is a lightning strike or spark from a power line to start a blaze.

How global warming fuels extreme storms

As more heat is stored as energy in the atmosphere and oceans, it doesn’t just increase the temperature – it can also increase the amount of water vapor in the atmosphere.

When that water vapor condenses to liquid and falls as rain, it releases a large amount of energy. This is called latent heat, and it is the main fuel for all storm systems. When temperatures are higher and the atmosphere has more moisture, that additional energy can fuel stronger, longer-lasting storms.

Tropical storms are similarly fueled by latent heat coming from warm ocean water. That is why they only form when the sea surface temperature reaches a critical level of around 80 F (27 C).

With 90% of the excess heat from global warming being absorbed by the ocean, there has been a significant increase in the global sea surface temperature, including record-breaking levels in 2023.

Higher sea surface temperatures can lead to stronger hurricanes, longer hurricane seasons and the faster intensification of tropical storms.

Cold snaps have global warming connections, too

It might seem counterintuitive, but global warming can also contribute to cold snaps in the U.S. That’s because it alters the general circulation of Earth’s atmosphere.

The Earth’s atmosphere is constantly moving in large-scale circulation patterns in the forms of near-surface wind belts, such as the trade winds, and upper-level jet streams. These patterns are caused by the temperature difference between the polar and equatorial regions.

As the Earth warms, the polar regions are heating up more than twice as fast as the equator. This can shift weather patterns, leading to extreme events in unexpected places. Anyone who has experienced a “polar vortex event” knows how it feels when the jet stream dips southward, bringing frigid Arctic air and winter storms, despite the generally warmer winters.

In sum, a warmer world is a more violent world, with the additional heat fueling increasingly more extreme weather events.

( RFE/ RL ) – Record temperatures, prolonged droughts, and the drying up of rivers and lakes are displacing tens of thousands of Iranians each year, experts say.

Many of the climate migrants are farmers, laborers, and fishermen who are moving with their families from the countryside to major urban areas in Iran in search of alternative livelihoods.

Iranian officials have blamed worsening water scarcity and rising desertification on climate change. But experts say the crisis has been exacerbated by government mismanagement and rapid population growth.

While the exact number of climate migrants is unknown, Iranian media estimated that around 42,000 people in 2022 were forced to migrate due to the effects of climate change, including drought, sand and dust storms, floods, and natural disasters. The estimated figure for 2021 was 41,000. Observers say the real figures are likely much higher.

Experts say a growing number of Iranians are likely to leave rural areas as more areas of Iran — where most of the land is arid or semiarid — become uninhabitable every year.

“It is visible because Iran is very dry, there is little rainfall, and a significant part of the country is desert,” Tehran-based ecologist Mohammadreza Fatemi told RFE/RL. “As a result, the slightest change in the climate affects the population.”

Fatemi cited the drying up of the wetlands and lakes in Iran’s southeastern province of Sistan-Baluchistan as an example. The Hamun wetlands were a key source of food and livelihood for thousands of people. But as the wetlands have diminished, many locals have migrated to the cities.

“Many people lived there, [but] they all moved to [the provincial capital] Zahedan and [the city of] Zabol,” said Fatemi. Now, he adds, many are moving from these cities to other provinces.

Environmentalist Mehdi Zarghami from Tabriz University recently estimated that some 10,000 families have left Zabol for other parts of Iran during the past year due to drought and sandstorms.

Fatemi estimates that around 70 percent of migration inside Iran is driven by the effects of climate change. “We’ve entered the phase of crisis. The next level could be a disaster,” he said.

‘Water Bankruptcy’

Some Iranian officials have warned that many parts of the Islamic republic could eventually become uninhabitable, leading to a mass exodus from the Middle Eastern country.

In July, officials warned that more than 1 million hectares of the country’s territory — roughly equivalent to the size of Qom Province or Lebanon — is essentially becoming unlivable every year.

Aljazeera English: “Iran drought: Residents flee villages as water shortages set in”

In 2018, then-Interior Minister Abdolreza Rahmani Fazli said that drought and water scarcity could fuel “massive migration” and eventually lead to a “disaster.”

Iran is among the countries most vulnerable to climate change in the Middle East, which is warming at twice the global average.

Ahad Vazifeh of Iran’s Meteorological Center said in October that average temperatures in Iran had increased by 2 degrees in the past 50 years.

But experts say that climate change only partly explains the environmental crisis that Iran is grappling with.

Tehran’s failed efforts to remedy water scarcity, including dam building and water-intensive irrigation projects, have contributed to the drying up of rivers and underground water reservoirs.

Kaveh Madani, the director of the United Nations University Institute for Water, Environment, and Health, told RFE/RL’s Radio Farda that Iran’s “water bankruptcy” had been fueled by government mismanagement and the building of dozens of dams.

“Iran’s consumption is more than its natural sources of water,” he said. “Therefore, [the authorities are] using underground sources of water. [In response,] the wetlands have dried up, rivers have dried up, and now climate change has added to this equation.”

“Temperatures are rising, there’s more dust, soil erosion will increase, and desertification will increase,” predicted Madani, a former deputy head of Iran’s Environment Department.

The government’s mismanagement of Iran’s scant water resources has triggered angry protests in recent years, especially in drought-stricken areas.

Water scarcity has also led to conflict. Iran and Afghanistan engaged in deadly cross-border clashes in May after Tehran demanded that its neighbor release more upstream water to feed Iran’s endangered southeastern wetlands.

Social Problems

Some experts say rapid population growth in Iran has also contributed to the environmental crisis, although growth has slowed in recent years.

Iran’s population has more than doubled since the 1979 Islamic Revolution, rising from about 35 million to almost 88 million, with about 70 percent of the population residing in cities.

Climate migration has put a growing strain on infrastructure and created socioeconomic problems in Iranian cities, including rising poverty, homelessness, and overcrowding, experts say.

Researcher Mohammad Reza Mahbubfar told the Rokna news site in February 2021 that Tehran was a major destination for many of the country’s climate migrants. “Contrary to what officials say — that Tehran has a population of 15 million — the [real] figure has reached 30 million,” he said.

Mahbubfar added that “unbalanced development” had “resulted in Tehran being drowned in social [problems].”

The influx has led some wealthier Tehran residents to move to the country’s northern provinces, a largely fertile region that buttresses the Caspian Sea.

“My mother, who has a heart problem, now spends most of her time in our villa in Nowshahr,” a Tehran resident told Radio Farda, referring to the provincial capital of Mazandaran Province.

“My husband and I are hoping to move there once we retire to escape Tehran’s bad weather and pollution,” the resident said.

Reza Aflatouni, the head of Iran’s Land Affairs Organization, said in August that about 800,000 people had migrated to Mazandaran in the past two years.

Local officials have warned that Mazandaran is struggling to absorb the large influx of people.

Although 2023 saw the beginnings of an El Nino climate phenomenon, which brings extra heat every few years, the El Nino effects were still small this year and most of the increase in heating was owing to humans having put billions of tons of greenhouse gases into the atmosphere (which they are still doing steadily, instead of reducing emissions).

Moreover, NOAA says, we have seen 537 (soon to be 538) months in a row of temperatures above the average for the twentieth century.

That statistic means that no one born after 1978 has ever lived through a normal year of temperatures, as we twentieth-century people knew them (I’m 71). We moved a lot and my father was stationed for a few months at places like Fort Dietrich in Maryland and Fort Dix in New Jersey. I can’t remember now when and where, but I recollect joining with other children to tunnel beneath the snow in the winter. Do children do that now? Last year Maryland had virtually no snow, and Baltimore got 0.2 inches. That absence of snowfall was admittedly a little extreme and may not be repeated in 2024, but this world is clearly not the one I grew up in.

Taylor Swift, born 1989, doesn’t know what a normal year is like. She is literally a force of nature. The megastar has made headlines when her fans danced and stomped so hard to the loud music at her concert in Seattle that they produced a mild earthquake. But mother nature is angry and is more powerful still.

We are heating our world so rapidly and so extremely by burning coal, fossil gas and gasoline that even Swift herself is being overtaken by climate effects.

It has just been confirmed that Ana Clara Benevides Machado, 23, who attended Swift’s Eras Tour concert in Rio de Janeiro on November 17 died of heat exhaustion.

Rio that day was 102 F. (39C), but because of humidity it felt like 138.7 F. (59.3C). Scientists have discovered fairly recently that humans cannot survive very high “wet bulb” temperatures, where both the temperature and the humidity are unusually elevated. We cool down by sweating, and very high heat and humidity don’t allow sweating to have that cooling effect. So our brains boil.

Ms Swift herself seemed at some points during her conference to be gasping for breath. She had her staffers distribute water and threw out some bottles herself. She canceled her scheduled Nov. 18 follow-up concert because of the extreme heat and Ms. Machado’s death.

Page 6: “Taylor Swift struggles to breathe while performing during deadly Brazil Eras Tour”

Mid-November is the beginning of summer in the southern hemisphere, but even so you didn’t used to see over 100 degrees F. in Rio at that time. Things are changing, and not for the better. Latin America didn’t really have a spring this year, suffering heat domes with temperatures as high as 104 F. (40C) even in August and September. (I was once in Rio for a conference in July and it was cold and rainy.) Those elevated, unseasonable temperatures were made 100 times more likely by the climate crisis, reports Scientific American.

Rio was not alone in seeing anomalous temperatures in 2023.

In just one week of summer 2023, 20,000 air flights were affected by the extreme heat globally. Thunderstorms, cracked take-off lanes, and — if it gets to 117 degrees F. or higher, thin air — can all interfere with flights.

Some twenty southern and southwestern cities in the US experienced either unprecedentedly high temperatures or unprecedentedly long heat waves, or both. Phoenix hit 110 degrees F. on 54 days this summer. Dallas-Fort Worth was also hit by a heat dome, which extended down into Mexico.

Friends, we are doing this to ourselves, every day, all day. We are hitting golf balls in our bathrooms and are surprised when they boomerang on us. It won’t get better until we stop. That probably means we have to stop electing Republicans. At all. And we have to pressure even the Dems, constantly, to do the right thing. This thing is too big for us as individuals to solve it. We need government, and the Dem Inflation Reduction Act was a good start. More of that.

The year 2023 was marked by extraordinary heat, wildfires and weather disasters.

In the U.S., an unprecedented heat wave gripped much of Texas and the Southwest with highs well over 100 degrees Fahrenheit (37.8 Celsius) for the entire month of July.

Historic rainfall in April flooded Fort Lauderdale, Florida, with 25 inches of rain in 24 hours. A wave of severe storms in July sent water pouring into cities across Vermont and New York. Another powerful system in December swept up the Atlantic coast with hurricane-like storm surge and heavy rainfall. California faced flooding and mudslides from a series of atmospheric rivers early in the year, then was hit in August by a tropical storm – an extremely rare event there.

Wildfires ravaged Hawaii, Louisiana and several other states. And Canada’s worst fire season on record sent thick smoke across large parts of North America.

Globally, 2023 was the warmest year on record, and it wreaked havoc around the world. El Niño played a role, but global warming is at the root of the world’s increasing extreme weather.

So, how exactly is global warming linked to fires, storms and other disasters? I am an atmospheric scientist who studies the changing climate. Here’s what you need to know.

Dangerous heat waves and devastating wildfires

When greenhouse gases, such as carbon dioxide from vehicles and power plants, accumulate in the atmosphere, they act like a thermal blanket that warms the planet.

These gases let in high-energy solar radiation while absorbing outgoing low-energy radiation in the form of heat from the Earth. The energy imbalance at the Earth’s surface gradually increases the surface temperature of the land and oceans.

NASA: “What Is the Greenhouse Effect?”

The most direct consequence of this warming is more days with abnormally high temperatures, as many countries saw in 2023.

Extreme heat waves hit large areas of North America, Europe and China, breaking many local high temperature records. Phoenix went 30 days with daily high temperatures at 110 F (43.3 C) or higher and recorded its highest minimum nighttime temperature, with temperatures on July 19 never falling below 97 F (36.1 C).

Although heat waves result from weather fluctuations, global warming has raised the baseline, making heat waves more frequent, more intense and longer-lasting.

That heat also fuels wildfires.

Increased evaporation removes more moisture from the ground, drying out soil, grasses and other organic material, which creates favorable conditions for wildfires. All it takes is a lightning strike or spark from a power line to start a blaze.

Canada lost much of its snow cover early in 2023, which allowed the ground to dry and vast fires to burn through the summer. The ground was also extremely dry in Maui in August when the city of Lahaina, Hawaii, caught fire during a windstorm and burned.

How global warming fuels extreme storms

As more heat is stored as energy in the atmosphere and oceans, it doesn’t just increase the temperature – it can also increase the amount of water vapor in the atmosphere.

When that water vapor condenses to liquid and falls as rain, it releases a large amount of energy. This is called latent heat, and it is the main fuel for all storm systems.

When temperatures are higher and the atmosphere has more moisture, that additional energy can fuel stronger, longer-lasting storms. This is the main reason for 2023’s record-breaking storms. Nineteen of the 25 weather and climate disasters that caused over US$1 billion in damage each through early December 2023 were severe storms, and two more were flooding that resulted from severe storms.

Tropical storms are similarly fueled by latent heat coming from warm ocean water. That is why they only form when the sea surface temperature reaches a critical level of around 80 F (27 C).

With 90% of the excess heat from global warming being absorbed by the ocean, there has been a significant increase in the global sea surface temperature, including record-breaking levels in 2023.

Higher sea surface temperatures can lead to stronger hurricanes and longer hurricane seasons. They can also lead to the faster intensification of hurricanes.

Hurricane Otis, which hit Acapulco, Mexico, in October 2023, was a devastating example. It exploded in strength, rapidly intensifying from a tropical storm to a destructive Category 5 hurricane in less than 24 hours. With little time to evacuate and buildings not designed to withstand a storm that powerful, more than 50 people died. The hurricane’s intensification was the second-fastest ever recorded, exceeded only by Hurricane Patricia in 2015.

A recent study found that North Atlantic tropical cyclones’ maximum intensification rates increased 28.7% between the 1971-1990 average and the 2001-2020 average. The number of storms that spun up from a Category 1 storm or weaker to a major hurricane within 36 hours more than doubled.

The Mediterranean also experienced a rare tropical-like cyclone in September 2023 that offers a warning of the magnitude of the risks ahead – and a reminder that many communities are unprepared. Storm Daniel became one of the deadliest storms of its kind when it hit Libya. Its heavy rainfall overwhelmed two dams, causing them to collapse, killing thousands of people. The heat and increased moisture over the Mediterranean made the storm possible.

Cold snaps have global warming connections, too

It might seem counterintuitive, but global warming can also contribute to cold snaps in the U.S. That’s because it alters the general circulation of Earth’s atmosphere.

The Earth’s atmosphere is constantly moving in large-scale circulation patterns in the forms of near-surface wind belts, such as the trade winds, and upper-level jet streams. These patterns are caused by the temperature difference between the polar and equatorial regions.

( Tomdispatch.com) – A recent opinion poll rocked the world of the Big Oil lobbyists in their proverbial thousand-dollar suits and alligator shoes. The Pew Research Center found that 37% of Americans now feel that fighting the climate crisis should be the number one priority of President Joe Biden and Congress, and another 34% put it among their highest priorities, even if they didn’t rank it first. Companies like ExxonMobil and countries like Saudi Arabia have tried since the 1990s to gaslight the public into thinking climate change was either a total fantasy or that the burning of coal, natural gas, and petroleum wasn’t causing it. Having lost that battle, the fossil-fuel lobbyists have now fallen back on Plan B. They want to convince you that Big Oil is itself swinging into action in a major way to transition to — yes! — green energy.

The hosting of the recent COP28 climate summit by the United Arab Emirates, one of the world’s leading petroleum exporters, exemplified exactly this puffery and, sadly enough, it’s just one instance of this greenwashing world of ours. Everywhere you look, you’ll note other versions, but it certainly was a classic example. Emirati businessman Sultan Ahmed al-Jaber served as president of the Dubai-based 28th Conference of Parties — countries that had signed onto the United Nations Framework Convention on Climate Change (UNFCCC) in Rio de Janeiro in 1992. While his green bona fides include his role as chairman of the board of the UAE’s green energy firm Masdar, controversy swirled around him because he’s also the CEO of ADNOC, the UAE’s national petroleum company. Worse yet, he’s committed to expanding the oil and gas production of his postage-stamp-sized nation of one million citizens (and eight million guest workers) in a big-time fashion. He wants ADNOC to increase its daily oil production from its present four million barrels a day to five million by 2027, even though climate scientists stress that global fossil-fuel production must be reduced by 3% annually through 2050 if the world is to avoid the most devastating consequences of climate change.

Meanwhile, since COP28 was held in the heart of the petroleum-producing Middle East, it also platformed bad actors like Saudi Arabia, which led the charge to stop the conference from committing to ending the use of fossil fuels by a specific date. The awarding of COP28 to the Emirates by the UNFCCC Secretariat allowed a whole country, perhaps a whole region, to be greenwashed, a genuinely shocking decision that ought to be investigated by the U.N.’s Office of Internal Oversight Services. (And next year, it looks like COP29 will be hosted by another significant oil producer. In other words, the oil countries seem to be on a hot streak!)

Imaginary Algae

Mind you, those Gulf oil states are anything but the only major greenwashers on this planet. After all, the private sector has outdone itself in this arena. A congressional investigation into the major oil companies produced a long report and an appendix that came out last year, including internal corporate emails showing repeated and systemic bad faith on the subject of climate change. ExxonMobil executives, for instance, had publicly committed their company to the goals of the 2015 Paris Agreement to keep the increase in the average surface temperature of the earth to no more than 1.5° Centigrade (2.7° Fahrenheit) above the pre-industrial era. Although a 1.5-degree increase might sound small, keep in mind that, as a global average, it includes the cold oceans of the higher latitudes, the North and South Poles, and the Himalayas. In already hot climates like South Asia and the Middle East, that means over time it might translate into a stunning 10- to 15-degree increase that could make some places literally unlivable.

Scientists worry that exceeding that level could throw the world’s climate system into full-scale chaos, producing mega-storms, substantial sea level rise, ravaging wildfires, and deadly heat and drought over large parts of the earth’s surface. Still, despite his public commitment to it in 2019, the CEO of ExxonMobil, Darren Woods, asked an oil industry lobbying group to delete a reference to the 2015 Paris climate agreement from the draft of a statement on sustainability it had prepared. That mention, Woods said, “could create a potential commitment to advocate on the Paris agreement goals.” So much for oil company pledges!

In a similar fashion, in 2020, executives of the London-based Shell PLC asked public relations employees to highlight that the company’s vow to reach zero net carbon emissions by 2050 was “a collective ambition for the world,” rather than a “Shell goal or target.” As a company executive admitted all too bluntly, “Shell has no immediate plans to move to a net-zero emissions portfolio over our investment horizon of 10-20 years.” (Oh, and in case you missed this, the profits of the major fossil-fuel outfits have in recent years gone through the roof.)

Buy the Book

Nor is corporate greenwashing simply a matter of public pronouncements by oil company executives. ExxonMobil has run a multi-million-dollar campaign of television and streaming advertising attempting to pull the wool over people’s eyes about what it’s doing. In one instance, it paid the New York Times to run an extended commercial gussied up as if it were a news article, a shameful procedure to which the Times acquiesced. Studies show that most readers miss disclaimers about such pieces actually being paid advertisements. It was entitled, “The Future of Energy? It may come from Where you Least Expect: How scientists are tapping algae and plant waste to fuel a sustainable energy future.” The advertisement was extremely misleading. As Chris Wells, an associate professor of emerging media studies at Boston University’s College of Communication, told BU Today last February, “Exxon is doing a lot of advertising around its investments in algae-based biofuels. But these technologies are not yet viable, and there is a lot of skepticism that they ever will be.”

In fact, about a month after Wells gave that interview, ExxonMobil admitted publicly that it had pulled out of algae biofuels research entirely at the end of 2022, having invested about $29 million a year over 12 years. It spent more millions, however, in advertising to give the public the impression that this paltry investment outweighed the company’s multi-billion-dollar efforts to bring ever more petroleum online.

The environmentalist group Client Earth notes that ExxonMobil spends between $20 billion and $25 billion annually looking for — yes, of course! — new oil fields and is committed to doing so through at least 2025. The company had a net profit of $55.7 billion in 2022. In other words, it’s still devoting nearly half of its annual profits to looking for more petroleum when, of course, it could be using them to launch its transition to sustainable forms of energy. Such — to put it politely — inertia is clearly unwise. New electric vehicle sales in the U.S. soared to about a million this year alone, and EVs will have avoided using 1.8 million barrels of oil in 2023. Better yet, the cost of battery packs for the vehicles fell 14% and is expected to keep heading down, guaranteeing that EVs will be ever more affordable over time. Moreover, in significant parts of the rest of the world, as the New York Times reported recently, electric-powered two- and three-wheeled vehicles are beginning to give the giant oil companies a run for their money. In the decades to come, ExxonMobil’s inflexibility and refusal to innovate will undoubtedly doom the company, but the question remains: In the process, will it doom the rest of us, too?

A Deceptive Greenwashing Marketing Campaign

In another, better world, the courts could punish the oil majors for their greenwashing. That misleading paid ad in the New York Times forms but one cornerstone of a wide-ranging lawsuit against ExxonMobil by the state of Massachusetts, initiated in 2019, which has so far survived that company’s legal challenges. As the office of Attorney General, Andrea Campbell explains, it is “alleging that the company violates Massachusetts law through a deceptive ‘greenwashing’ marketing campaign that misleadingly presents Exxon as a leader in cutting-edge clean energy research and climate action… and… its products as ‘green’ while the company is massively ramping up fossil fuel production and spending only about one-half of 1% of revenues on developing clean energy.” Campbell, an African-American born in Boston, is keenly aware that climate change is an equity issue, since its deleterious effects will initially be felt most strongly among the less privileged. (Of course, given our present Supreme Court, don’t hold your breath on this one.)

In its complaint, the state points to marketing campaigns like those featured on ExxonMobil’s YouTube channel, which still shows an ad produced eight years ago, “Making the World’s Energy go Further,” that, in just 30 seconds, presents a medley of greenwashing’s greatest early hits — algae biofuel, “new technology for capturing CO2 emissions,” and cars twice as efficient in their gas mileage. Algae biofuels, however, have by now bitten the dust; there is no affordable and safe method of capturing and storing carbon dioxide; and electric cars are between “2.6 to 4.8 times more efficient at traveling a mile compared to a gasoline internal combustion engine,” according to the Natural Resources Defense Council. 

The biggest fault in such commercials, however, is that the oil company’s ad makers were trying to convince the public that ExxonMobil was putting major resources into sustainable alternatives.  As the state of Massachusetts points out, in reality “ExxonMobil has ramped up production and reportedly is now the most active driller in the Permian Basin, the shale oil field located in western Texas and southeastern New Mexico that yields low-cost oil in months, rather than the years required for larger offshore projects to begin producing crude… ExxonMobil has invested billions of dollars into the development of massive Canadian oil sands projects, which are among the costliest and most polluting oil extraction projects in the world.”

Carbon Capture and Lake Nyos

An even more dangerous scam than algae biofuels (implausible but not life-threatening) is the idea of carbon capture and storage (CCS). Remind me: Why would we try to store billions of tons of a poisonous gas? On August 21, 1986, subterranean carbon dioxide deposits bubbled up through Lake Nyos in Cameroon, killing nearly 2,000 people, thousands of cattle and other animals, and in the process turned four local villages into graveyards. Some scientists fear similar underground carbon dioxide storage elsewhere could set off earthquakes. And what if such quakes in turn release the gas? Honestly, since I still remember the 1989 Exxon Valdez disaster where 11 million gallons of oil, spilled into the waters off Alaska, wrecked hundreds of miles of shoreline and killed unknown numbers of sea creatures and birds, I’d just as soon not have ExxonMobil store carbon dioxide in my neighborhood.

Worse yet, most of the CO2 harvested by oil companies so far has been injected into drill sites to help bring in — yes, you guessed it! — more petroleum. Worse yet, studies have shown that carbon-capture technology itself emits a lot of carbon dioxide, that it can only capture a fraction of the CO2 emitted by fossil fuels, and that just shutting down coal, fossil gas, and petroleum production and substituting wind, solar, hydro, and batteries is far safer, cheaper, and better for the environment. 

Carbon capture is, however, a favorite greenwashing tool of Big Oil, since company executives can pretend that a technological breakthrough somewhere on the horizon justifies continuing to spew out record quantities of CO2 in the present moment. Senator Joe Manchin (D-WV) wasted billions of taxpayer dollars by including provisions for CCS research and development in Joe Biden’s otherwise admirable Inflation Reduction Act. In the process, he managed to insert a key greenwashing technique into even the most progressive climate legislation ever passed by an industrialized hydrocarbon state.

As for Sultan Al-Jaber, the head of COP28, he let his mask slip in November in a testy exchange with former Irish President Mary Robinson, who had invited him to an online discussion of how women’s lives could be improved if the climate crisis were effectively addressed. When she urged him to act as president of COP28, he exploded: “I’m not in any way signing up to any discussion that is alarmist. There is no science out there, or no scenario out there, that says that the phase-out of fossil fuel is what’s going to achieve 1.5C.” He was pushing back against the goal advocated by scientists and many diplomats of quickly phasing hydrocarbons out. He claims to advocate phasing them down, not presumably eliminating them. He added, “Please help me, show me the roadmap for a phase-out of fossil fuel that will allow for sustainable socioeconomic development, unless you want to take the world back into caves.” Al-Jaber was posturing, since he surely knows that the International Energy Agency has issued just such a roadmap, which does indeed require rapid reductions in fossil fuel use. Oh, and if he has his way, it’s quite conceivable that, somewhere down the road, the capital city of the United Arab Emirates, Dubai, could become too hot to be livable.

Given the plummeting cost of green energy, it’s clear that moving quickly and completely away from fossil fuels will improve the quality of life for people globally while making energy cheaper. In the end, COP28 could only issue an anodyne call for “transitioning away” from fossil fuels. Despite al-Jaber’s globe-straddling greenwashing at the climate summit, however, there is no realistic alternative to phasing fossil fuels not just down but out, and on an accelerated timeline, if our planet’s climate isn’t to turn into a Frankenstein’s monster. After all, 2023 has already proved a unique year for heat — with month after month of record-setting warmth across the globe. And sadly, as fossil-fuel production only continues to increase, that’s just the beginning, not the end, when it comes to potentially broiling this planet.

Admittedly, under the best of circumstances, this transition would be challenging and, according to the United Nations, will certainly require more investments than the countries of the world are now making, but it still appears eminently achievable. As for ExxonMobil and other oil majors, every day they resist investing their obscene profits in truly innovative green energy technology is a day they come closer to future financial ruin. In the meantime, they are, of course, wreaking historically unprecedented harm on the planet, as was all too apparent with the serial climate disasters of 2023, now believed to be the hottest of the last 125,000 years.

It’s now almost inevitable that 2023 will be the warmest year ever recorded by humans, probably the warmest for at least 125,000 years.

Multiple temperature records were smashed with global average temperatures for some periods well above 1.5°C. Antarctic sea ice loss is accelerating at frightening rates along with many other indicators of rapid climate change. Does this mean 2023 is the year parts of the climate tip into a much more dangerous state?

Most people expect that if a system, like someone’s body, an ecosystem, or part of the climate system, becomes stressed, it’ll respond fairly predictably – double the pressure, double the impact, and so on. This holds in many cases, but is not always true. Sometimes a system under stress changes steadily (or “linearly”) up to a point, but beyond that far bigger or abrupt changes can be locked in.

An example of such “nonlinear” changes are “tipping points”, which happen when a system is pushed past a threshold beyond which change becomes self-sustaining. This means that even if the original pressure eased off the change would keep on going until the system reaches a sometimes completely different state.

Think of rolling a boulder up a hill. This takes a lot of energy. If that energy input is stopped then the ball will roll back down. But when the top of the hill is reached and the boulder is balanced right at the very top, a tiny push, perhaps even a gust of wind, can be enough to send it rolling down the other side.

The climate system has many potential tipping points, such as ice sheets disappearing or dense rainforests becoming significantly drier and more open. It would be very difficult, effectively impossible, to recover these systems once they go beyond a tipping point.

We along with 200 other scientists from around the world just published the new Global Tipping Points Report at the COP28 UN climate talks in Dubai. Our report sets out the science on the “negative” tipping points in the Earth system that could harm both nature and people, as well as the potential “positive” societal tipping points that could accelerate sustainability action.

Here we look at the key messages from report sections on tipping points in the Earth system, their effects on people, and how to govern these changes.

Tipping points in air, land and sea

Having scoured scientific evidence of past and current changes, and factored in projections from computer models, we have identified over 25 tipping points in the Earth system.

Six of these are in the icebound parts of the planet (the “cryosphere”), including the collapse of massive ice sheets in Greenland and different parts of Antarctica, as well as localised tipping in glaciers and thawing permafrost. Sixteen are in the “biosphere” – the sum of all the world’s ecosystems – including trees dying on a massive scale in parts of the Amazon and northern boreal forests, degradation of savannas and drylands, nutrient overloading of lakes, coral reef mass mortality, and many mangroves and seagrass meadows dying off.

Finally, we identified four potential tipping points in the circulation of the oceans and atmosphere, including collapse of deep ocean mixing in the North Atlantic and in the Southern Ocean around Antarctica, and disruption of the West African monsoon.

Human activities are already pushing some of these close to tipping points. The exact thresholds are uncertain, but at today’s global warming of 1.2°C, the widespread loss of warm water coral reefs is already becoming likely, while tipping in another four vital climate systems is possible. These are Greenland and West Antarctic ice sheet collapse, North Atlantic circulation collapse, and widespread localised thaw of permafrost.

Beyond 1.5°C several of these become likely, and other systems like mangroves, seagrass meadows, and parts of the boreal forest start to become vulnerable. Some systems can also tip or have their warming thresholds reduced due to other drivers, such as deforestation in the Amazon.

It can be hard to comprehend the consequences of crossing these tipping points. For example, if parts of the Amazon rainforest die, countless species would be lost, and warming would be further amplified as billions of tons of carbon currently locked up in trees and soils makes its way into the atmosphere. Within the region, this could cause trillions of dollars of economic impacts, and expose millions of people to extreme heat.

Given the sheer scale of risks from tipping points, you may assume that economic assessments of climate change include them. Alas, most assessments effectively ignore tipping point risks. This is perhaps the most frightening conclusion of the new report.

Human societies could tip into something much worse

There is also the potential for negative tipping in human societies, causing further financial instability, displacement, conflict or polarisation. These would hamper our efforts to limit further Earth system tipping points, and could even bring about a shift to a social system characterised by greater authoritarianism, hostility and alienation that could entirely derail sustainability transitions.

A further risk is that most of Earth’s tipping systems interact in ways that destabilise one another. In the worst case, tipping one system makes connected systems more likely to tip too. This could produce a “tipping cascade” like falling dominoes.

The Global Tipping Points Report makes clear that climate change is a key driver for most of these tipping points, and the risk of crossing them can be reduced by urgently cutting greenhouse gas emissions to zero (which “positive tipping points” could accelerate). To help prevent tipping points in the biosphere, we’ll also need to rapidly reduce habitat loss and pollution while supporting ecological restoration and sustainable livelihoods.

Ambitious new governance approaches are needed. Our report recommends international bodies like the UN’s climate talks urgently start taking tipping points into account. Their understanding of dangerous climate change needs a serious update.

( Cronkite News ) – The arid West is getting drier, and shrinking water supplies pose a boatload of risks to human health throughout the region.

Those findings come from a new federal report on climate change that also covers a broad range of hazards brought on by changing climate patterns due to human activity, from flooding to wildfires, drought to rising sea levels.

The Fifth National Climate Assessment identified drying in the Colorado River basin as one of the greatest climate risks facing the Southwest, as well as the region’s biggest area for future climate mitigation and adaptation.

The problem hinges on one key fact: The Southwest is getting drier, and it’s likely not a temporary phenomenon. Climate change is shrinking the amount of water on the surface and underground, replacing the normal ebb and flow of occasional drought with a permanent resetting of the baseline for how much water the region should expect to see each year, a process scientists call “aridification.”

Higher temperatures mean a shorter snow season and less water piling up as snow. Two-thirds of the Colorado River starts as snow in the state of Colorado. At the same time, the snow that does fall is being absorbed by thirsty soil and failing to make it all the way to rivers.

Heidi Steltzer, a professor of environment and sustainability at Fort Lewis College in Durango, Colorado, said that means people living in a dry region will have to shift their behaviors and develop practices that use less water.

“If we don’t have a lot of snow in any given winter, or over a five or 10 year stretch, where and how can we shift to some of these behaviors that ensure everybody has enough, even if it’s not as much as we used to have?” Steltzer asked.

Steltzer didn’t work on the Fifth National Climate Assessment but helped author a major United Nations climate report in 2019. She said rural communities, which often steward much of the nation’s land and natural resources through agriculture, should be a bigger part of conversations about combating climate change.

The new federal climate report doesn’t include many new scientific findings, but rather summarizes a lot of existing research and puts it in a context that is accessible to the general public. It also highlights the human health risks brought on by climate change. Across the country, those risks include heat-related deaths, breathing problems induced by poor air quality and wildfire smoke, and mental trauma brought on by natural disasters.

The report said already-marginalized groups – such as people of color, people with disabilities, and people experiencing homelessness- are disproportionately vulnerable to those climate-related health hazards.

The assessment’s authors say the latest report has an increased focus on climate justice compared to previous reports. In the Southwest, the report highlights drought-related health risks for Native American communities.

Heather Tanana, a law professor at the University of California, Irvine, who focuses on tribal water infrastructure and Indigenous health policy, helped author the report.

“In the Southwest, a lot of Native American homes don’t have infrastructure to get clean running water or sanitation,” she said. “The climate impacts of drought or flooding in an area where infrastructure is not sufficient is just going to make those inequities worse.”

Tanana said fixing those problems starts with better data about the impacts of climate change. Climate data about tribal communities, in particular, has historically been limited.

“When we have better data, we’re able to be more adaptive to implement climate solutions,” she said.

Water policymakers across the Southwest are currently working on new ways to reduce demand as a response to shrinking water supplies brought on by climate change. State leaders are under pressure to agree on new water management rules by 2026, when the current set of guidelines for managing the Colorado River expires. They are also facing steady calls to give tribal groups a larger voice in those negotiations.
