His guardian angel's still looking out for him then. Good.

"Pulses of extra melting and uplift imply that we'll experience pulses of extra sea level rise," said Mr. Bevis."

The island is rising, so that means it's sinking!

jso2897: Something something is the tinfoil hat that Bevis uses to keep something out of his something.

Where is the Bev, haven't seen him post in awhile.

IIRC, he can haz banninated.

A new study released Friday finds that Greenland has risen in recent years as the rate of ice melting has increased, a startling revelation that scientists attribute to global warming.

It's called isostatic rebound and there's nothing startling about it.

Hmmm, his profile is still up. Strange quote on there.

Yep. Been going on for the past 17,000 years.

If I'm doing my sums correctly, that 100 billion tonnes of meltwater adds a small fraction of a millimeter to the sea level. 100 billion tonnes is roughly 1x10^⁹ cubic meters of water, or 100 km^³. The ocean's surface area is 361x10^⁶ km² water (70.8 %).

And, 100 km^³ divided by 361x10^⁶ km^² = 2.78x10^^-4 meters to the sea level. That's about 0.278 millimeters per year...or about 1 inch sea level rise in 90 years if it happened every year for 90 years.

I think humanity has more pressing issues...like what Michelle Bachmann will wear to the next debate.

unyon: In fact, most models expressing this rate of change have turned out to be far too conservative.

I would imagine that most models don't use the isostacy input from one small section along the edge of a craton and project that across the entire craton.

But I came to only comment that this was news a year ago. It's not really news now, is it?

unyon: That makes the assumption that this little sliver of Greenland is the only place experiencing significantly higher than average melting. That assumption is woefully inaccurate. In fact, most models expressing this rate of change have turned out to be far too conservative.

On the contrary, I make no such assumption. What I wrote accounts for Greenland's contribution to sea level rise, which is all I referenced. I made no mention of other sources of sea level rise whatsoever. That said, the sources I've read suggest that the same factors causing Greenland's melt in total contribute about a millimeter to sea level rise per year, or about 4" per century at the present rate.

The sea level has been steadily rising for better than 17,000 years, but in numerous studies the rate of rise appears to be slowing down and going asymptotic on the horizontal axis. Presuming no significant changes to global climate we can expect as much as another meter or so of sea level rise over the next few thousand years, irrespective of human activity, or even presence.

Here is a very readable paper that addresses the topic: Late Pleistocene to Holocene History of
San Francisco Bay (9mb pdf). See page 16 for an illuminating graphic from several studies conducted at various sites around the world.

PS - Hmm, I cant seem to get that link to work...google on 'holocene history of san francisco bay' for a UC-Berkeley link.

Dammit, Bevis!

OMG! EVERYBODY PANIC! QUICK, SEND ALL OUR MONEY TO THE UNITED NATIONS --- IT'S THE ONLY WAY TO STOP THIS!

Obscure?

Not really. See the Boobies.

Boobies? See the Boobies

Ah forget it. Stupid Fark filter. See the top of the thread, Mr Walrus Onion.

/boobies!

crap, my bad

There are actually people outside the Twilight Zone named Mr. Bevis?

Do you think that's funny, Butthead?!

skodabunny: Boobies? See the Boobies

Right. Will do.

Did anyone try out the google map/earth layer where you could see what the earth would look like with up to 14m of ocean level rise?

Except for the morans who built places BELOW SEA LEVEL (new window) like some places in holland n stuff there really was no visible change really. I live less than 4 miles from the sea and even with 14m of rise I was still 2.5 miles from the sea.

I mean really, building a place to live BELOW SEA LEVEL? Guess which places are going to be on the news to show how the ocean rising is a huge problem...

A problem that is only a problem to morans is no problem.

This is the stupidest opinion I've ever heard formed. Do you think that sea level is a magical absolute that has a bright blue unchanging line that informed people 600 years ago that they should or should not build cities there?
