Climate Pledges Are Falling Short, and a Chaotic Future Looks More Like Reality
New York Times — By Max Bearak — Oct. 26, 2022 (Excerpts)
With an annual summit next month, the United Nations assessed progress on countries’ past emissions commitments. Severe disruption would be hard to avoid on the current trajectory.

Countries around the world are failing to live up to their commitments to fight climate change, pointing Earth toward a future marked by more intense flooding, wildfires, drought, heat waves and species extinction, according to a report issued Wednesday by the United Nations.
Just 26 of 193 countries that agreed last year to step up their climate actions have followed through with more ambitious plans. The world’s top two polluters, China and the United States, have taken some action but have not pledged more this year, and climate negotiations between the two have been frozen for months.
Without drastic reductions in greenhouse gas emissions, the report said, the planet is on track to warm by an average of 2.1 to 2.9 degrees Celsius, compared with preindustrial levels, by 2100.
That’s far higher than the goal of 1.5 degrees Celsius (2.7 degrees Fahrenheit) set by the landmark Paris agreement in 2015, and it crosses the threshold beyond which scientists say the likelihood of catastrophic climate impacts significantly increases.
With each fraction of a degree of warming, tens of millions more people worldwide would be exposed to life-threatening heat waves, food and water scarcity, and coastal flooding while millions more mammals, insects, birds and plants would disappear.
Wednesday’s report comes less than two weeks before nations are set to gather at U.N. climate talks in Sharm el Sheikh, Egypt, to discuss unfulfilled promises and take stock of the fight to stave off environmental catastrophe.
Shifting patterns.
The melting of the snowpack in the high Cascades has long been a source of sustenance in the Pacific Northwest. But as climate change makes seasons less predictable and precipitation more variable, people there are reimagining the region’s future and the tools that will be needed to manage it.
Facing drought.
The story of the Netherlands’ long struggles against excess water is written all over its boggy landscape. Now that climate change is drying it out, the Dutch are hoping to engineer once again their way to safety — only this time, by figuring out how to hold onto water instead of flushing it out.
A more extreme monsoon. South Asia’s annual monsoon is inextricably linked, culturally and economically, to much of Asia, bringing life-giving water to nearly one-quarter of the world’s population. But climate change is making the monsoon more erratic, less dependable and even dangerous, with more violent rainfall as well as worsening dry spells.
Wildfire smoke pollution. Smoke from wildfires has worsened over the past decade, potentially reversing decades of improvements in Western air quality made under the Clean Air Act, according to new research. Some areas in the Western United States had increases in particulate pollution from smoke that were about the same amount as the improvements in air quality from regulating factories and other sources of pollution.
But war in Europe, an international energy crisis, global inflation and political turmoil in countries like Britain and Brazil have distracted leaders and complicated cooperative efforts to tackle climate change.
On Monday, the European Union said it would increase its emissions reductions pledges “as soon as possible” but could not do so until its member states agreed on a number of upcoming climate laws.
That delay is “hugely disappointing” said Niklas Höhne, founder of the NewClimate Institute in Cologne, Germany.
“This year we’ve seen little of the climate action governments promised at the end of Glasgow, amid a deluge of new science telling us that we have to move faster, and that limiting warming to 1.5 degrees Celsius is still entirely possible. We need governments to set strong targets that drive emissions down, and decarbonize their economies.”
At last year’s global climate summit in Glasgow, countries pledged to redouble their efforts to cut the emissions from burning oil, gas and coal that are dangerously heating the planet. They also agreed to increase funding for technologies to help developing economies transition away from fossil fuels to wind, solar and other renewable energy sources.
The United Nations report analyzed the commitments made by countries to cut their emissions, known as nationally determined contributions, or N.D.C.s. Countries that signed the 2015 Paris agreement promised to update and strengthen their commitments every five years. The 2020 meeting was postponed a year because of the coronavirus pandemic. In 2021, acknowledging the urgency of the climate crisis, nations agreed not to wait another five years and instead pledged to make new commitments before the climate talks that begin Nov. 7 in Egypt.
Taryn Fransen, a senior fellow at the World Resources Institute, a research organization, called the current trajectory of global temperature increase “dangerously high.”
China, currently the world’s biggest emitter of greenhouse gases, is one of the major holdouts on new commitments, though it did submit a new pledge before last year’s summit in Scotland. China has said its carbon dioxide emissions will continue to grow until they peak by 2030, but it has not set targets for reducing other greenhouse gases, such as methane, which it emits in amounts large enough to equal the total emissions of smaller nations. . . .
An analysis by the World Resource Institute found that current promises by nations would reduce global greenhouse gas emissions by around 7 percent from 2019 levels, even though six times that, a reduction of 43 percent, would be necessary to limit global warming to 1.5 degrees Celsius. . . .
The United States, in passing the Inflation Reduction Act, which contains hundreds of billions of dollars in subsidies for cleaner technologies, has jumped forward in its ability to make good on its promise to cut emissions by between 50 and 52 percent below 2005 levels by the end of this decade.
But the new law will still only get the United States about 80 percent of the way to its current pledge to cut emissions, Ms. Fransen said. Mr. Höhne said the United States’ new law was the strongest move made by a major emitter in 2022, but was “30 years overdue.”
