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.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

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

Real Climate

Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). Rahmstorf, S., Robinson, A., Feulner, M.E.
