Greenhouse Gases

Senate Bill 253 calls for companies with more than $1 billion in sales doing business in California to publicly disclose their greenhouse gas emissions

Methane leaks from oil refineries and other facilities are a potent source of global warming—now satellites are working to spot culprits, all the way from space

A new kind of simulation, called a "digital twin," uses artificial intelligence to help cities better prepare for the challenges and threats of climate change

The equivalent of $3.7 million is being spent to selectively breed sheep to burp and fart less of the greenhouse gas methane.

"The uncontrolled release of natural gas is an environmental disaster," scientist Stefan Green said of the Darvaza crater, Turkmenistan's "Gateway to Hell."

Forty percent of Americans don't believe that eating less red meat would lower carbon emissions, according to a poll for Newsweek.

The concept is purely speculative for now and would require overcoming huge obstacles, but scientists said the idea was "feasible" in theory.

Generating electricity with green hydrogen fuels—predicted to become an important energy source in future—produces practically zero greenhouse gas emissions.

California's plan to go all electric on new cars by 2035 is far more ambitious than past clean-air efforts—but high risk given how unreliable the power grid is.

Walker, set to face off against Senator Raphael Warnock in a December runoff election, faced ridicule for the remarks made during an Augusta campaign stop.

"Everything about billionaires is damaging to the environment," Beatriz Barros, an environmental justice researcher at Indiana University, told Newsweek.

Researchers have found huge swathes of infrastructure across the 970,000 square mile area will be at risk by 2050.

These lakes form because warm temperatures in the Arctic are melting the permafrost.

The California Air Resources Board said if passed, the proposal could save 5,000 lives between 2024 and 2050.

To help the country's future food security, Biden has said the U.S. government will invest in "cultivating alternative food sources" and other biotechnologies.

Climatologists have said that extreme heatwave events will increase by 30 percentage points in the future, mostly due to greenhouse gases.

Scientists say the rapid rise in atmospheric methane has significant implications because it is a potent greenhouse gas and can contribute to global warming.

Which countries are leading the way when it comes to the challenges of tackling climate change, living sustainably and protecting the environment?

"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."

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.

The world's nations emit hugely different quantities of heat-trapping greenhouse gases into the atmosphere.

Win-win situations that generate usable electricity by reducing greenhouse gases and make money simultaneously are ones that should be supported by our state and federal policies; not forced to shut down.

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

"The precious Amazon is teetering on the edge of functional destruction and, with it, so are we," the editors of a leading scientific journal wrote.

The leak emitted more of the gas in 20 days than the oil and gas industries of some European nations do in a year.

"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.

Researchers reconstructed atmospheric carbon dioxide concentrations dating back 2.5 million years.

The gases are warming the atmosphere.

The machine may help mitigate some of the excess CO2 in the atmosphere.
