"Why did thousands of cattle all die in a heat wave?" Greene tweeted. "Usually just the old, sick, or weak die in stressful conditions, not the whole herd."

Researchers in Australia say transporting food around the world causes three gigatons of gasses to be emitted every year.

Bovine burps give off enormous amounts of the greenhouse gas methane every year, prompting environmental concern.

Photographer Neill Drake has recreated a photo from 1918 to show the melting of the Norwegian Blomstrandbreen Glacier.

Methane—the greenhouse gas burped out by cows—could be a sign of life on other planets for scientists using the James Webb Space Telescope.

A new study found only about 6 percent of pandemic recovery spending by G20 countries was used in areas that cut greenhouse-gas emissions.

"The government remains convinced that nuclear power cannot be classified as sustainable," a government spokesman said.

Under the new rule, vehicle mileage standards would be raised beginning in the 2023 model year so that new vehicles could hit the 40 mpg target by 2026.

All railroads cautioned that at this stage, they are only pilot tests, and new options won't be ready to replace diesel locomotives for several years at least.

State regulators will consider increased regulations on emissions from semi-trucks, and a ban on the sale of new small gas engine products like leaf blowers.

The state passed a law mandating Californians to put their food waste in a separate bin so it can be composted or turned into biogas, an energy source.

The federal government's buildings and contracts for goods and services will be carbon neutral, and its fleet of cars and trucks will be all electric by 2050.

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.

"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.
