Antarctic ‘Doomsday Glacier’ Is ‘Holding On By A Fingernail’

A new study found that the Thwaites Glacier in Antarctica, also known as the Doomsday Glacier, is disintegrating faster than previously believed due to climate change, and its collapse could cause a catastrophic rise in sea levels globally.

Ice loss from West Antarctica’s second largest marine ice stream, Thwaites Glacier, is currently a major uncertainty for future sea-level projections. Its bed deepens upstream to >2 km below sea level, and warm, dense, deep water delivers heat to the present-day ice-shelf cavity, melting its ice shelves from below, seriously affecting its stability.

Eastern Mediterranean, Middle East warming almost twice as fast as global average

The eastern Mediterranean and Middle East are warming almost twice as fast as the global average, with temperatures projected to rise up to 5 degrees Celsius (9 degrees Fahrenheit) by the end of the century if no action is taken to reverse the trend, a new report says.

The region will experience “unprecedented” heat waves, more severe and longer-lasting droughts and dust storms and rainfall shortages that will “compromise water and food security” for the region’s 400 million people. The eastern Mediterranean and the Middle East are more susceptible to warming trends because of their unique natural characteristics, like large desert expanses and lower water levels, the study said.
