Greenhouse gas emissions

Greta Thunberg warned of a "tsunami of greenwashing" to frame the deal as "a step in the right direction."

Foreign ministry spokesperson Maria Zakharova has attacked comments casting doubt on Russia's willingness to fight global warming.

As climate summit COP26 continues, take a look at the worst offenders—and their climate policies.

Dozens of countries have now promised to slash emissions of methane, a highly polluting greenhouse gas.

The World Health Organization said in a report published before the conference: "Climate change is the single biggest health threat facing humanity. The burning of fossil fuels is killing us."

Even as the pandemic caused a temporary decrease in fuel emissions, greenhouse gases in the Earth's atmosphere still increased.

"It's because of changes of the global local climate, especially. We have less humidity and less rainfall," said Petteri Taalas, secretary-general of the WMO.

Only half of Americans view climate change as an "existential threat" despite the dire warnings from scientists.

Scientists found that if greenhouse emissions are not limited areas with rich vegetation could become barren, and some coastal regions could disappear altogether.

"We have inherited a garden; we must not leave a desert to our children," the joint appeal said.

The U.S. government is set to up fuel economy standards. Scientists think that the best way is a combination of methods rather than moving straight to EVs.

"Why shouldn't they be able to learn how to use a toilet?" asked the study's co-author Jan Langbein.

President Biden just signed an executive order pushing for new car sales in the U.S. to be 50 percent electric by 2030. Carmakers might not be up to the task.

A proposal by the Environmental Protection Agency on rules to take strides towards combatting climate change is expected to be released as early as next week.

"It is not a mystery that China and the U.S. have many differences. But on climate, cooperation is the only way to break free from the world's current mutual suicide pact,'' he said.

"California plans on using rates to help drive the charging behaviors that are going to help the state electrify transportation while cutting carbon from the grid and saving ratepayers and drivers money," the California Energy Commission's Patty Monahan said.

Under Carper's proposal, the EPA would apply California's 2019 framework agreement on emissions standards reached between Ford, Volkswagen, Honda, BMW and Volvo.

Four more years of former President Donald Trump could have led the world's laggards to further stall efforts to curb climate change.

In the world of nature-based solutions, preventing deforestation will have the biggest near-term impact on slowing the rate of global warming.

The uncontrollable spread of the coronavirus led to huge declines in greenhouse emissions from the transportation, industry and power sectors across the country.

Many took to Twitter to point out that the drop in emissions was largely a result of the coronavirus pandemic which crippled the country for most of 2020.

However, researchers warn that the recent drastic falls are only likely be temporary.

"The pandemic is a reminder that there is no separation between humans and the environment," researcher Karen O'Neill said.

"I wouldn't be shocked to see a five percent or more drop in carbon dioxide emissions this year," researcher Rob Jackson said.

"Air pollution levels as observed by satellite are showing drastic improvements in many areas that have been undergoing restrictive quarantines," researcher Peter DeCarlo told Newsweek.

The walkout took place after Oregon Senate President Peter Courtney, a Democrat, stepped in to break a tie over the passage of the controversial cap-and-trade bill.

Sunday marks the anniversary of the Kyoto Protocol, when countries pledged to cut down their emissions. Fifteen years have passed and last year, greenhouse gas emissions were the highest they've ever been.

Permafrost is ground that remains frozen for a period of two or more years.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago," WMO Secretary-General Petteri Taalas said.

Nitrous oxide is 300 times more potent than carbon dioxide as a greenhouse gas, although it is found in the atmosphere in smaller quantities.
