The ocean's color has changed significantly over the last 20 years, and the global trend is likely a consequence of human-induced climate change, report scientists at MIT, the National Oceanography Center in the U.K., and elsewhere.
The latest climate report by the Intergovernmental Panel on Climate Change states that the international community is very unlikely to limit the global temperature rise to 1.5°C, if immediate action is not taken.
This massive ice stream is already in a phase of fast retreat (a "collapse" when viewed on geological timescales) leading to widespread concern about exactly how much, or how fast, it may give up its ice to the ocean.
Greenland's rapidly melting ice sheet will eventually raise global sea level by at least 10.6 inches (27 centimeters)—more than twice as much as previously forecast—according to a study published Monday.
The Arctic has warmed nearly four times faster than the rest of the planet over the last 40 years, according to research that suggests climate models are underestimating the rate of polar heating.
