Earth’s Most Famous Climate Scientist Issues Bombshell Sea Level Warning

Slate has the article Earth’s Most Famous Climate Scientist Issues Bombshell Sea Level Warning.

The study—written by James Hansen, NASA’s former lead climate scientist, and 16 co-authors, many of whom are considered among the top in their fields—concludes that glaciers in Greenland and Antarctica will melt 10 times faster than previous consensus estimates, resulting in sea level rise of at least 10 feet in as little as 50 years.

We conclude that continued high emissions will make multi-meter sea level rise practically unavoidable and likely to occur this century. Social disruption and economic consequences of such large sea level rise could be devastating. It is not difficult to imagine that conflicts arising from forced migrations and economic collapse might make the planet ungovernable, threatening the fabric of civilization.

Bernie Sanders is calling for massive infrastructure spending. What he didn’t plan on is how much effort we need to put into building dikes. Forget the border fence to stop the “flood of Mexicans”, Donald Trump has his eyes focused on the wrong flood.

Yesterday I was watching a discussion on The Weather Channel about the disposition of various ice masses on the globe. They were saying what you would expect about the Arctic and about Greenland.

Then they commented that the sea ice of Antarctica was actually increasing. I thought, “You twits, of course it is increasing. It is dropping of the land and into the sea.” However, they were not twits. They went on to make almost the same point. The melting freshwater on land is flowing into the sea. The salty sea waters freezes at a much lower temperature than the fresh water from land. For this reason, the land water flowing into the ocean produces more ice than the sea water that melted lost in ice coverage.
