From more frequent wildfires to rising sea levels, climate change is disrupting ecosystems and upending once-stable weather patterns. One particularly alarming consequence of rising global ...

For decades, we've heard the same urgent warnings,glaciers melting, Arctic ice disappearing, sea levels rising,all blamed on ...

New Study Reveals Arctic Ice, Tracked Both ... an international team of scientists has compiled data from 2001 to 2018 to explore both surface and basal freezing/thaw cycles and uncover the ...

The ice cap’s core of so-called multiyear ice, which persists year-round, has shrunk by about 40 percent in four decades, kicking off a vicious cycle: as more ice melts, more ocean water is ...

The region reaches its maximum extent of sea ice in March of each year, which then begins to melt. This process takes roughly six months. The NSIDC said the measurement of sea ice taken Saturday ...

Sea ice cycles naturally throughout the year, and it's already floating. ... If we can moderate emissions somewhat, the Arctic may only be ice-free from August to October by 2100.

Using 366 simulations conducted on 11 climate models, Heuzé and Jahn found we may experience ice-free days within three to six years from the most recent year with at least 3.39 million km 2 (1. ...

Arctic sea ice’s biggest year since record-keeping began was 1979, at 6.42 million square miles (16.64 million square kilometers). That means since satellites began tracking it, ...

The Arctic is the early warning system for climate change and the loss of sea ice is a clear sign it’s in trouble, scientists say. It should be reaching its annual maximum levels of ice at this ...

Arctic sea ice experienced its weakest winter buildup on record, with a peak measurement of 5.53 million square miles, 30,000 square miles smaller than the previous low in 2017.
