The U.S. plans to reduce greenhouse gas emissions dramatically in the next decade. Scientists say it's crucial that the U.S. succeed. Still, many of the positive effects won't arrive for decades.
With surgical care on the rise globally, researchers worry the energy-consuming procedures will have a negative impact on the climate. But they say there are ways to make them more energy efficient.
A new study shows that when ads made hedonistic marketing claims, such as "exotic" or "delicious," rather than targeting environmental interests, more people were willing to try eating insects.
Greenhouse gas concentrations reached a record high. Global sea level was the highest on record, too. NOAA's State of the Climate report points to the urgency of addressing climate change.
Walmart has promised big cuts in emissions of greenhouse gases. To meet that goal, though, the giant retailer may have to persuade farmers to use less fertilizer. It won't be easy.
Researchers say 30 percent to 50 percent of the ice loss is due to natural variation in temperature and humidity, while human-caused warming is responsible for the rest.
New research calculates the greenhouse gas emissions involved in making bread, from wheat field to bakery. The vast majority of emissions come from one step in the process: farming.
What's the single most important thing that the world's farmers could do to reduce global warming? Give cattle — especially in the tropics — faster-growing, more nutritious pasture.
It has been a common belief that low-emissions vehicles, like hybrids and electric cars, are more expensive than other choices. But researchers at MIT have found otherwise.
The two nations topping the world in greenhouse gas emissions agreed at the Paris talks to cut way back. But critics have stalled a key part of the U.S. plan, and China's good start may be fragile.
The Kyoto Protocol of 1997 didn't slow down the gradual warming of the planet. Now governments meeting for a two-week summit are trying an a la carte approach.
The proposal includes a nationwide cap-and-trade system beginning in 2017. China and the United States are the No. 1 and No. 2 emitters of heat-trapping carbon pollution.
The majority of Americans favor government action, but the candidates — and big donors — differ greatly. Here is what they've said on the topic, beginning with whether climate change is real.
The international report card is out and confirms the hottest average on record — for a third time in 15 years. More than 400 scientists contributed data, finding a spike in sea and air temperatures.
The Environmental Protection Agency hasn't outlined any specific emissions limits for aircraft engines, but it has begun the process that would lead to them.
The new target was submitted to the UN Framework Convention on Climate Change Tuesday. It is part of a plan for a new international treaty to be hammered out in December in Paris.
He directed the federal government to cut emissions by 40 percent within the next decade and to increase its use of renewable energy sources to 30 percent of total consumption.
