Effect Of Greenland Melt On Sea Level


By Paul Homewood



There was one more thing that I meant to include in the Greenland ice sheet post yesterday, the effect on sea levels.

DMI like to talk in terms of Gt, which I’m sure sounds very impressive.

However, when converted into sea level rise, it becomes distinctly less so:


So even during this period of recent melt, we are only talking of 0.65mm a year, or about two inches a century.

We know that global sea levels were rising just as fast as now in the mid 20thC, so it seems unlikely that much has changed on the Greenland ice sheet since the 1930s.

And, of course, we also know that ice mass is probably increasing in Antarctica.
