Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

In an era when massive heat domes blanket large swaths of continents for days, wildfires burn through areas the size of small countries, and hurricanes regularly push the limits of what we once thought possible, sea level rise can seem like extreme weather’s low-key cousin. Since 1993, sea level has risen by an average rate of 3.1

Why is future sea level rise still so uncertain?

Real Climate

Three new papers in the last couple of weeks have each made separate claims about whether sea level rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. 2020) or Sadai et al. But there is more.

The water south of Greenland has been cooling, so what causes that?

Real Climate

An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2). So in comparison, the cooling effect of a 15 % AMOC slowdown is over 1,000 times larger than the direct cooling effect of the Greenland meltwater. References.

Phantastic Job!

Real Climate

Warm temperatures prior to the Ordovician glaciation, rises of temperature through the Devonian, a dip through the Carboniferous, peaking again at the beginning of the Triassic, slightly cooler in the Jurassic, peaking again mid-Cretaceous and then (roughly speaking) cooling into the Neogene (and the last 3 million years of ice age cycles).
