Researchers report that warming from short-lived compounds — greenhouse gases such as methane, chlorofluorocarbons, or hydrofluorocarbons, that linger in the atmosphere for just a year to a few decades — can cause sea levels to rise for hundreds of years after the pollutants have been cleared from the atmosphere.Image Credit: Flickr/Wayne Butterworth.

Global temperatures showing the change from pre-industrial times. The global temperatures for January to September 2016 were approximately 1.2°C above pre-industrial levels and 0.88°C (1.58°F) above the average for the 1961-1990 reference period.Credit: NOAA; NASA/ UK Met Office; CRU It is very likely that 2016 will be the hottest year on record, with global temperatures

Compare the extension of older sea ice in the Arctic in September 1984 and September 2016. The older ice is thicker and more resistant to melt than new ice, so it protects the sea ice cap during warm summers. In September 1984, there were 1.86 million square kilometers of old ice (5 years or older)

The image above, taken during a high-priority flight that IceBridge carried on Aug. 29, shows Helheim Glacier, with its characteristic wishbone-shaped channels, as seen from about 20,000 feet in the sky. Helheim is one of Greenland’s largest and fastest-melting glaciers.Credit: NASA Operation IceBridge, NASA’s airborne survey of polar ice, is flying in Greenland for the

After an extreme global warming 252 million years ago, a severe mass extinction of life took place on Earth. A new study in the Arctic has been seeking clues as to what limited return of life to world´s oceans after this event.Credit: © duncan / Flickr Extreme global warming 252 million years ago caused a
