Building and operating telescopes can generate a lot of greenhouse gases. In fact, it's as if each astronomer in the world was driving more than 100,000 miles per year, a new study finds.
Nuclear power is emerging as an answer as states transition away from coal, oil and natural gas to reduce greenhouse gas emissions and stave off climate change.
Carbon offsets got a big boost from November's U.N. climate summit. New rules could make it easier for companies to pay for carbon-cutting projects in other countries, rather than doing it themselves.
A town in northern England wants to open a coking coal mine to create jobs. But while hosting the U.N. climate summit, Prime Minister Boris Johnson is urging countries to slash greenhouse gases.
Scientists said the concentration of carbon dioxide, which contributes to climate change, is the highest in data going back 800,000 years, based on ice core records.
The companies face an existential threat as more governments and businesses move to tackle climate change. So a growing number have their own plans to decarbonize, by creating renewable gas.
Scientists say the next decade is crucial for slowing climate change. To catch up, Biden's environmental policies will have to move faster than any in history.
The tech giant, which says it has been "carbon neutral" for years, is vowing to go "carbon negative" — by cutting emissions, planting trees and investing in new carbon removal technology.
In the search for alternatives to coal and gas, some European countries have turned to a very old fuel. They're importing wood from the United States. Some environmentalists say it makes no sense.
Carbon emissions from global air travel are rising fast, and U.S. passengers make up the largest share. But some are vowing not to fly at all, motivated by guilt and concern for the environment.
SACRAMENTO, Calif. (AP) — Nevada has joined twenty-two other states in suing to stop the Trump administration from revoking California's authority to set emission standards for cars and trucks.
The young Swedish activist led a protest at the White House on Friday. But she wasn't looking to go inside. "I don't want to meet with people who don't accept the science," she says.
China has taken dramatic steps to fight climate change, including shutting major coal power plants. But now it plans to build hundreds of coal plants abroad.
After several years of nearly no growth in planetary carbon emissions, human-created carbon output is projected to rise again. That means the past few years were a pause, not a peak, researchers say.
The industry has been in decline for years, partly because burning coal creates CO2 and warms the atmosphere. But there's a way to capture it — which has drawn praise from traditional enemies.
The idea behind "clean coal" is technology that would capture for reuse most of the carbon dioxide emitted by coal-burning power plants. Entrepreneurs aim to use similar tech to clean natural gas.
Capturing carbon emissions from coal plants would reduce coal's effect on climate change. But high costs and other factors have stymied efforts to use that technology at more U.S. power plants.
