If the high emissions continue, major ice shelves will collapse by 2070, according to the report, which also suggests sea level rise would accelerate to rates not seen in 20,000 years. Furthermore, ocean acidification and over-fishing will alter Southern Ocean ecosystems, and a failure to mana...
Since the 1970s, Arctic sea ice has undergone unprecedented change, becoming thinner, less extensive and less resilient to summer melt. Snow’s high albedo greatly reduces solar absorption in sea ice and the upper ocean, which mitigates sea–ice melt and ocean warming. However, the drivers of...
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. That’s because of something that could be
