Global warming is an increase in the average temperature of the earth's surface over time. This rise results from the "greenhouse effect," in which gases such as carbon dioxide trap heat within the earth's atmosphere. The climbing temperatures could cause catastrophic climate change. History In ...

NASA's Operation IceBridge monitors Earth's changing glaciers and ice sheets, like Alaska's Sheridan Glacier, seen here from an August, 2018 flight. Sheridan Glacier has a rapidly disintegrating floating tongue (the portion of glacier that extends beyond the shoreline and floats on the w...
Global warming is basically just one big part of climate change. Climate change encompasses plenty of other disastrous things besides the Earth’s rising temperatures, such as sea levels rising, destruction of ecosystems, ice mass loss, and natural disasters, as per NASA. ...

[听力原文]26-27 The vast arctic ice cap is shrinking so fast it could melt away completely before the end of this century. These are the dire warnings from NASA scientists who say they are stunned by the findings. They claim more ice on the North Pole is disappearing every year because ...
In 1988, NASA scientist James Hansen admitted that he was 99 percent certain that global warming is linked to human activity. After two years, the Intergovernmental Panel on Climate Change declared that ...
Photo byNASA Goddard Photo and Video Definition Global warming is the term used to refer to the increase in the average temperature of the air near the Earth's surface and the oceans. This phenomenon is thought to have begun in the 1950s, and it is expected to continue well into the fut...
