Aren't almost all of the flooding estimates wildly pessimistic?

Aren't most estimates of sea level rise somewhat less than 1-2m?  This will still be catestrohpic in certain areas, but  nothing like the massive and widespread flooding this tool suggests.

I just posted it because I thought it's interesting - more like a what if than a "omg look what's going to happen!"

From what I gather, they're saying if all the polar ice melts we're looking at 60m rise + a bit more from the glaciers that presumably will also melt under those conditions. I don't think anyone is projecting the icecaps to melt completely in the near future.

:lol:  Back in the 70s when everyone was worried about global cooling, Jake would've been sharing scary glaciation maps.

Unlikely, given my age at the time.

:lol: Now in 2013, people who proudly celebrate willful ignorance repeat a talking point borne out of proud willful ignorance.

I always thought that the global cooling thing was more tied to nuclear winter than anything.

Nah - I vaguely remember reading some 70s-era sci-fi that talked about a new ice age.

Well that settles it then.

Glad I could help. :)

That conforms with garbon's link to wikipedia:
QuoteGlobal cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the scientific understanding of ice age cycles. In contrast to the global cooling conjecture, the current scientific opinion on climate change is that the Earth has not durably cooled, but undergone global warming throughout the 20th century.

Which again is consistent with dguller's link.

I'm glad you're all in agreement :cheers:
