According to a report issued Wednesday by the United Nations, countries around the world are not living up to their commitments to fight climate change.
More ambitious plans have followed through for just 26 of the 192 countries that agreed last year. Climate negotiations between the United States and China have been frozen for months despite the two countries taking some action.
The report said that without drastic reductions in greenhouse gas emissions, the planet is on track to warm by an average of 2.1 to 2.9 degrees Celsius by the year 2200.
The goal of 1.5 degrees Celsius was set by the landmark Paris agreement in 2015, and it crosses the threshold beyond which scientists say the likelihood of catastrophic climate impacts increases.
Millions more people would be exposed to life threatening heat waves, food and water scarcity, and coastal flooding as a result of each fraction of a degree of warming.
Less than two weeks before the U.N. climate talks in Sharm el Sheikh, Egypt, the report was released.
War in Europe, an international energy crisis, global inflation and political turmoil in countries such as Britain and Brazil have distracted leaders and complicated efforts to tackle climate change.
There are shifting patterns In the Pacific Northwest, the melting of the snow in the high mountains has been a source of sustenance. Climate change is making seasons less predictable and precipitation more variable, but people there are rethinking the region's future and the tools that will be needed to manage it.
The area is facing a shortage of water. The story of the Netherlands has been told all over its boggy landscape. The Dutch are trying to engineer once again their way to safety by figuring out how to hold onto water instead of throwing it out.
A lot of rain. The monsoon in South Asia brings life-giving water to 25% of the world's population. Climate change is making the monsoon more unpredictable, less reliable and even dangerous, with more violent rain and dry spells.
The smoke from the wildfire is polluted. According to new research, smoke from wildfires may be reversing decades of improvements in Western air quality. There was an increase in particulate pollution from smoke that was the same amount as the improvement in air quality from regulating factories and other sources of pollution.
Relinquishing a large amount of money. The founder of the outdoor apparel maker, Yvon Chouinard, gave his company's ownership to a trust and an organization dedicated to fighting climate change. At a time when billionaires talk about making the world a better place, they often don't match reality.
On Monday, the European Union said it would increase its emissions reductions pledges, but only if its member states agree on a number of upcoming climate laws.
The founder of the New Climate Institute in Cologne, Germany, said that the delay was hugely disappointing. There has been little of the climate action governments promised at the end of Glasgow, despite a lot of new science telling us that we have to move faster and limit warming to 1.5 degrees Celsius. Strong targets that drive emissions down and decarbonize economies are needed by governments.
At last year's global climate summit in Glasgow, countries pledged to double their efforts to cut emissions from burning oil, gas and coal. They agreed to increase funding for technologies to help developing economies transition away from fossil fuels.
N.D.C.s are commitments made by countries to cut emissions. The countries that signed the Paris agreement promised to strengthen their commitments over time. The meeting was delayed because of the coronaviruses. After acknowledging the seriousness of the climate crisis, nations agreed to make new commitments before the climate talks begin in Egypt in November.
Taryn Fransen is a senior fellow at the World Resources Institute.
One of the major hold outs on new commitments is China, which submitted a new pledge before last year's summit in Scotland. China 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 countries.
China stopped building coal-burning power plants abroad last year. According to the Center for Research on Energy and Clean Air, as of August, 26 out of 104 such projects had been put on hold.
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.
A few countries have updated this year. According to Ms. Fransen of the World Resources Institute, India, Australia, and Indonesia followed through on their commitments. Each of those countries made up for lost time by failing to update their N.D.Cs.
The United States has made good on its promise to cut emissions by between 50 and 52 percent by the end of the decade, thanks to the Inflation Reduction Act, which contains hundreds of billions of dollars in subsidies for cleaner technologies.
The new law will only get the US about 80 percent of the way to cutting emissions. Mr. Hhne said that the United States' new law was 30 years late.
This year's climate summit, known as the Conference of Parties, will be dominated by the war in Ukraine, as well as a number of other climate disasters such as floods in Pakistan and Nigeria.
Poor countries that have not contributed much to the problem of climate change and are the least prepared for it should be compensated by wealthy nations that have contributed the most. An agreement on compensation is unlikely to be reached, but the topic is expected to be on the agenda for the first time.
Lesser-developed and low-lying island nations will try to get compensation through the creation of an international fund. The creation of such a fund has been opposed by the United States, Europe and other wealthy countries because they fear being held legally responsible for the costs of disasters.
Those in the developing world were quick to point out that most of the countries that increased their pledges this year are not heavy polluters.
Mo Ibrahim, a Sudanese-British businessman turned philanthropist who has convened African leaders to discuss the climate crisis ahead of the summit in Egypt, said that the latest U.N. report showed that those most responsible for the climate crisis remained unwilling to face up to their responsibilities. The developing world will continue to pay the bill unless urgent action is taken to hold richer countries to account.
One of the world's leading health journals published a report about the threat of fossil fuels to human health.
The report raised concerns not only about the direct health consequences of rising temperatures, including heat-related mortality, pregnancy complications and cardiovascular disease, but also the indirect costs, including the effects that drier soil could have on nutrition and how a changing climate can expand habitats suitable to mosquitoes that carry a disease
Climate change is driving severe health impacts all around the world, while the persistent global fossil fuel dependence compounds these health harms amidst multiple global crises, according to Marina Romanello.
John Kerry called on China, Russia, Saudi Arabia and Mexico to align their climate policies with the goal of limiting global warming to 1.5 degrees.
The top 20 economies are responsible for 80 percent of emissions, according to Secretary of State John Kerry. He said they should strengthen their pledges this year.
He said that people agreed to do that. It takes a lot of people to do the job.
