Sea Level Rise

A prominent ice dome in northern Greenland completely melted around 7000 years ago during a warmer period, according to new research. Scientists warn that similar temperatures could return by 2100 due to human-induced climate change, highlighting the ice sheet's vulnerability. This discovery provides crucial insights into potential future sea level rise.

Spinning underwater vortices, known as submesoscale storms, are responsible for 20 percent of the ice melt under the Thwaites glacier's ice shelf in Antarctica. These features trap warm deep water beneath the ice, accelerating melting in a feedback loop. As the climate warms, they could intensify and contribute to greater sea level rise than previously anticipated.
