To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That's always puzzled scientists, but now they think they know what happened.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.
Despite clear air as a result of the pandemic reducing human activities, our emissions still soar.
Global warming has increased plant growth and helped offset increases in carbon dioxide emissions.
From Nairobi to Los Angeles, pandemic lockdowns have cleared pollution from the skies. But those blue vistas may be temporary, and shutdowns aren't slowing climate change.
Bubbly waters are becoming increasingly popular. While these carbonated, sometimes flavored beverages might cause slight harm to teeth, they are far better than soda. They might even be good for you.
Scientists are building up a picture of how much carbon can be taken out of the atmosphere and stored in coastal ecosystems.
Forests are remarkable at drawing carbon from the atmosphere, and they're getting better at it. New research highlights how important it is to protect forests so they can help us fight climate change.
