What history suggests about +3 to +4 degrees in sea level rise!

Study of ancient caves in Europe show how high sea levels should rise when temps go up 3 or 4 degree C.
You can figure about 20 to 60 feet (7 to 20 meters).
A study published in Nature looks at what water levels might look like in a +3 world.
The article is summed up in Phys.org.... Scientists discover evidence for past high-level sea rise.
Of course, you can always model the global warming on earth to see where we land with +2 or more degrees.
A scary study just out finds that ice sheets are melting from below at between 10 and 200 times faster than originally expected!

Another massive meltoff of Antarctic glacier. Really ugly likely outcomes.

The melting of Antarctica was already really bad. It just got worse. http://wapo.st/19rU1xp
Wow. Another area, like the west of antartcica, could result in massive ice melt from the ocean side up!
Each shelf/sheet could add about 10 feet to ocean rise, maybe 25% more for the northern hemisphere.
Ouch!

Climate change: Sea ice, global cooling, and other nonsense

Climate change: Sea ice, global cooling, and other nonsense:

I was rather pleased in my travels last week to get a glimpse of the news that the Arctic ice caps had been expanding again. They had been shrinking, and getting smaller at an increasing rate, so statistically, we were certainly due for a recovery. I saw a 60% recovery, however, so I was a little skeptical.

So I just now get a chance to check into it, only to find that the Global Cooling Loon David Rose was at it again, spreading (lies?) misinformation around the nation (UK). You often wonder if he is let out of the asylum, or simply makes this stuff up inside.

You wonder who, if anyone anywhere, would possibly be served by printing such blatant miss-information.

Here's a great article about the whole thing by Plait. (@BadAstronomer)

A 60% recovery of the ice caps? Look at the graphic. Last year was so horrible that ships were easily able to navigate the north pole. This could have, and should have, gotten everyone's attention everywhere.

So this year wasn't that bad. Yeah!:-)

It was bad, however. Ouch!:-( ... With more than 1 standard deviation below "normal" for the last 30 years. On a grade-point scale, I would rank this as moving from a low F to an F+. (Plait offered up a D- grade, but was probably grading on the curve.)

So DailyMail gets some traffic, from printing this garbage. The people who take the headline and run, continue to get steered down a dead-end hole of misinformation.

Nonsense.
