What is your estimate for sea level rise?

Question

say in the next century?

mine is between 2 and 5 metres.

this researcher (have to admit a bias, anyone called svetlana gets my attention) reckons between 0.8 and 1.5m in this new study. hansen reckons between 1 and 5 metres but i think he is being coy.

your best guess?

Answer 1

A total of 5 or 6 millimeters average, maybe 2 centimeters at peak.

Answer 2

50 metres.

The rate of melting in Greenland and Antarctica is increasing exponentially vice linearly due to human contribution of greenhouse gasses.  In addition, it's not just the melting rate that will affect sea level.  Huge, state size chunks of ice several kilometres thick will periodically slide into the ocean increasing the level in significant steps.

Answer 3

long beach wa is expected to loose land within 10 years, the length of a football Field that is a LOT....that pretty much stands for the whole pacific NW coastline.

Answer 4

It has been rising for millenia due to no fault from humans and is expected to continue.  If humans contribute to any rising, it is extemely minor.  Your estimate of 5 meters (15 feet) is silly but it was certainly less than some others.

Answer 5

100-200 metres

You know I've always said 60 metres, until somebody corrected me and convinced me I was wrong.  70 it is then!

Hmmm.  I assumed you meant the water level.  The eastern ice is still miles thick.

Answer 6

Somewhere between a drop of 5 cm and a rise of 5 cm.

Answer 7

Well, I think it's going to rise real fast 2-4 feet...then it'll fall back 2-4 feet...then it'll rise real fast 2-4 feet...we call them tides over here.

Answer 8

20 to 30 feet?
