Greenland ice melt has surged and scientists are alarmed

More from the article ...

... Climate change is dramatically reshaping how Greenland's ice sheet melts, according to a new study led by the University of Barcelona and published in Nature Communications. Researchers found that extreme melting events are now happening more often, covering larger areas, and producing significantly more meltwater than in the past.

Since 1990, the surface area affected by these extreme events has been expanding by about 2.8 million km2 per decade. At the same time, the amount of water released from melting ice has surged. Between 1950 and 2023, extreme melt events produced an average of 12.7 gigatons of water per decade. Since 1990, that figure has jumped to 82.4 gigatons per decade, marking a sixfold increase.

Record-Breaking Melt Events Are Becoming More Common

Most of the most intense melting episodes have occurred in recent decades. Seven of the ten most extreme events on record have taken place since 2000, including major events in August 2012, July 2019, and July 2021. These events stand out because they have no comparable dynamic precedents, highlighting how unusual current conditions have become. ...

How far inland does one have to go in Florida to get a couple feet above sea level?

... As the director of Social and Sustainable Enterprises at Florida State University, I've spent years examining the growing risks of rising sea levels in South Florida. Working alongside graduate research students, we've analyzed data from coastal monitoring stations and economic reports, revealing patterns that demand immediate attention from policymakers and residents alike.

The water is rising, and we're already feeling it

Let's start with what we can all see with our own eyes. Last year's "king tide" season " those extra-high tides between September and November " flooded Miami Beach and downtown streets, disrupting traffic and businesses. These aren't hurricanes or tropical storms but "sunny-day floods."

The numbers tell a clear story: Florida's water levels have risen 8 inches since 1950, and are now rising as much as 1 inch every three years. Scientists project that sea levels could rise 10 to 17 inches higher by 2040 than they were in 2000. That might not sound like much, but every inch counts in a place as flat as Miami. ...
