The United States has demonstrated international leadership on climate change in the past, but recent setbacks are presenting new challenges for President Biden.
Across the country, local governments are accelerating their efforts to cut greenhouse gas emissions, in some cases bridging partisan divides. Their role will become increasingly important.
Today the rhetorical war has largely been won, but the outlook grows a lot more confusing when everyone agrees to agree.
One company says it has the technology. And though investors looking for cleaner power generation are lining up, some environmentalists are skeptical.
Environmentalists say the government failed to study the threats to endangered species from climate change before issuing oil and gas drilling permits.
Carbon emissions are forever so carbon removal should be, too.
Humans pumped 36 billion tons of the planet-warming gas into the atmosphere in 2021, more than in any previous year. It comes from burning oil, gas and coal.
’’About a year ago, President Joe Biden set an ambitious climate target: The US should cut its greenhouse gas emissions roughly in half by 2030. That’s consistent with what we’d need to do to reach some of the goals of the Paris Agreement, but it provides very little time to get our emissions under control.
That raises some obvious questions. Is it even possible? If so, how? To find out, a group of energy experts used six different models of the US energy economy, tasking each with reaching a state where emissions are consistent with our goals. The good news is that all the models provide routes to getting there. While the exact details vary from model to model, their common features strongly hint at where our focus needs to be.
Greenhouse gas emissions come primarily from energy use, both for generating electricity and powering transportation. Industrial processes can also release either carbon dioxide or other greenhouse gasses, some of which have an even higher warming potential. It’s possible to track the costs and benefits of altering the weight of each of these sources. In some cases, it can involve switching an industrial process to alternate materials or from fossil fuels to a renewable source. Alternately, it could include offsetting continued emissions through things like carbon capture or reforestation.
A global buyers’ club of more than 50 companies, including Microsoft and Ford Motor, say they will buy “green” steel, aluminum and other commodities by 2030.

Climate scientists and fossil fuel executives use the same terms when they talk about an energy transition. But they mean starkly different things.
President Biden wants electricity generated from wind, solar and other clean sources. The Tennessee Valley Authority plans to invest in fossil fuels instead.
Reforestation can fight climate change, uplift communities and restore biodiversity. When done badly, though, it can speed extinctions and make nature less resilient.
Rising oil prices and increased demand for expanded production come at a time when scientists say nations must sharply cut the use of fossil fuels.
The Justice Department is pausing new federal oil and gas leases and permits after a judge blocked the government from weighing the cost of climate damage in decisions.
A European satellite reveals sites in the United States, Russia, Central Asia and elsewhere that are “ultra emitters” of methane. That could help fight climate change.
Scientists say rocks on the English coast contain clues of the processes that drove the end-Triassic event that killed as much as a quarter of all life on Earth.
The company has big plans to turn its delivery fleet green. But very few of the vehicles are made right now.
The finding, by European researchers, fits a clear warming trend: The seven hottest years on record have been the past seven.
Under the new plan, designed to reduce planet-warming tailpipe emissions, new vehicles would be required to average 55 miles per gallon starting in 2026.
Air Eau de Parfum smells like fig leaf, orange peel and jasmine. It comes from carbon emissions.
The federal government would stop buying gasoline-powered vehicles by 2035 and its buildings would be powered by wind, solar or other carbon-free electricity by 2050.
The landscape resembles frozen spinach left out on the kitchen counter too long.
To visitors, the Norwegian archipelago can seem both ethereal and eternal. But climate change all but guarantees an eventual collapse of its vulnerable ecosystem.
Some fungi sprout in fiery shades of orange and pink after wildfires, feasting on what was left behind by the burn.

An Indiana city has the most roundabouts in the country. They’ve saved lives and reduced injuries from crashes — and lowered carbon emissions.
The $555 billion package is designed to lure the country away from fossil fuels. It faces an uncertain path in the Senate.
In Washington, Beijing, New Delhi and beyond, governments face conflicting forces — political, social and economic — that will shape their next steps in the effort to avert a climate crisis.
After running a day past its scheduled end date, COP26 ended with a signed agreement, though many called it disappointing.
Some activists called the agreement in Glasgow disappointing, but it establishes a clear consensus that all countries need to do much more.
At COP26, negotiators from about 200 countries worked overnight, hashing out differences in the quest for a new global climate agreement
As nearly 200 nations struggle over global climate negotiations, the world’s two biggest polluters sign an agreement that is short on details..
Plans for new power generation won’t meet global climate goals.
The plans, while short on specifics, represent a notable step toward cutting greenhouse gas emissions from hospitals and the health care industry, a sizable emitter globally.
Negotiators from about 200 countries are entering Week 2 of climate talks trying to resolve big issues around money, transparency and timelines.
Scientists say carbon removal may be needed to avert the worst effects of climate change. But it still needs to be much cheaper and more reliable.
The United States did not agree to stop coal development at home but promised to halt overseas funding of oil, gas and coal.
