Back in the early 1960s, the US Army conducted a secret Cold War operation beneath Greenland’s frozen tundra.

Now a chance rediscovery from that operation could rewrite the history of the north-west Greenland ice sheet, and our understanding of its stability.

Published in Science today, the findings indicate a region of north-west Greenland was completely ice free 400,000 years ago when temperatures in the region were similar to global average temperatures today.

That has huge implications for our understanding of how the Greenland ice sheet will respond to climate change, said study co-author Paul Bierman, a geologist from the University of Vermont.

“This is the evidence that Greenland can vanish. It’s not a model. It’s not a hypothetical. We know that the ice sheet vanished and it vanished under much less extreme conditions than we’re forcing the climate to right now.”

Systems have inertia and in general, the bigger the system the greater the inertia.

Take the example of an ice cube. Put it on a hot road and it won’t turn to water immediately, but it will start to melt fairly quickly.

Then imagine a block of ice the size of a car. It will obviously take much longer to melt, but the block will also cool the road, slowing the rate overall.

What this study shows, Dr Noble says, is we’ve already got the conditions for the Greenland ice sheet to melt, but the time frame is the million dollar question.

“Basically, the ice sheets haven’t had time to catch up with the amount of warming that’s present in the atmosphere and the oceans,” she said.

“And that’s what I guess is hard for people to comprehend, that we’ve actually locked ourselves in for thousands of years of warming and sea level rise.

“Even if humans make sacrifices and societies change rapidly, there’s still this inertia in the whole Earth system.”

If the entire Greenland ice sheet went, enough water would be released to put most of the world’s major cities underwater, she said.

No need to ask if your lobotomy is affecting your outlook.

No. PF is telling the exact truth.

It’s nice to know that the Greenland ice sheet has already melted without the slightest interference from human activity.
And without any significant extinctions of species.

Flooding of cities is a bit of a bummer, but it has been predicted since the 1980s.
It will occur in 20,000 years, or perhaps even sooner.

Perhaps if you read the article (I only grabbed a couple of sections), plus read my last post about methane below the permafrost, you might be able to make more sense of it. Why don’t you at least try, you might learn something.

What is the matter with you? Do you always have to act the fuckwit and a stupid troll. Grow up if you can and stop acting like a silly little schoolboy.

For your information you silly little boy. I do not smoke anything, nor do I do drugs and have even stopped drinking wine with my evening meal. I am certainly not a hippy, but someone that follows scientific ideals of which most of my posts reflect. So I would be obliged if you would pack up your fanciful ideas and get the medical attention you obviously need.

Yeah

Agree with OP.

Howard and Abbott did nothing.
When they should have been doing the opposite.

Idiots and environmental criminals.

No thinking for the future.

Like many Govenments around the world.

Remember back when Kevin was handing everyone 800/900 dollars and at the time on the forum I suggested that instead of doing that, they instead use that money to build renewable energy sources/ related ?

They could have installed a massive solar system on people’s roofs, done all kinds of things – but they didn’t. Most of that money was used to buy TVs – I’d bet they are in the tip now

With $900?

Considering that even after the cost of installing has reduced siince, the average small home is still going to need between 3 and 5 thousand dollars. $900 would not have gone anywhere near it.
