The spike was attributed to a slew of causes, including behavior changes after COVID-19 vaccines became widely available, but environmental advocates say it's worrisome.

President Biden's lofty domestic goals were brought down to earth by congressional opposition, notably from one Democratic senator. International efforts to fight planetary warming also fell short.

President Biden campaigned on the most ambitious climate agenda of any major party candidate. But the cornerstone of his plan appears doomed in Congress, rejected by a Democrat from a coal state.

Despite a year of increasing weather disasters, Biden's ambitious climate plans may be doomed in Congress.

President Biden campaigned on ending oil and gas industry subsidies. But getting rid of them requires passing legislation. A bill eliminating the overseas drilling subsidy is stalled in Congress.

In a sweeping executive order, President Biden aims to cut all climate warming emissions from federal government operations. The push dates to the Obama-era, and faces a lot of challenges.

The Biden administration is tapping into the country's emergency petroleum reserves in a bid to bring down high gas prices. But it's not clear how successful that strategy will be.

The Biden administration will release 50 million barrels of oil from the country's strategic petroleum reserve to lower gas prices for Americans as the holiday traveling season kicks off.

The infrastructure law includes money for capturing carbon from power plants and removing it from the air. Scientists say such technologies are crucial to avoiding the worst impacts of climate change.

The U.N. secretary-general warns the main goal of limiting global warming is "on life support." But Glasgow negotiators are making modest progress in their final hours.

New analyses find countries' latest climate promises are still not enough to meet the goal set in the Paris climate agreement. And they warn few countries even have plans to carry out their pledges.

In a major expansion, the new rules would apply not just to new operations but to older ones as well. Methane is a potent greenhouse gas, and considered key to slowing global warming quickly.

Australia says it is committed to addressing climate change, yet it exports huge amounts of coal and natural gas. There are calls for Australia to wind down global fossil fuel exports.

Under the Paris climate deal, exports of oil, gas and coal don't count toward a country's emissions. That's coming in for scrutiny as leaders gather for another global climate summit.

Even as the U.S. aims to cut climate-warming emissions at home, it still exports huge amounts of natural gas, oil and coal. That's coming in for scrutiny ahead of another global climate summit.

Americans love their gas stoves, but they pollute homes and are connected to a supply system that leaks methane. That's part of a battle as more people face a decision about switching to electric.

Environmentalists are optimistic a $150 billion plan to make the electricity grid more climate friendly will pass in Congress. Some utility companies say the cleaner energy goals are too aggressive.

Climate measures in a massive $3.5 trillion economic plan would transform the U.S. energy system. They are crucial for meeting President Biden's ambitious climate goals but face powerful opposition.

This week may be key for President Biden's ambitious climate goals. Congress is debating measures that are crucial for cutting carbon emissions and meeting U.S. obligations in the Paris climate deal.

People in the northeast were unprepared for tornadoes and flooding from Hurricane Ida. But these are the types of intense storms climate experts have long warned about.
