Sea level increases

[Ashokkumar01cbe]

The Arctic has lost more sea ice this year than at any time since satellite records began in 1979, Nasa says.

Scientists involved in the calculations say it is part of a fundamental change.

What is more, sea ice normally reaches its low point in September so it is thought likely that this year's melt will continue to grow.

Nasa says the extent of sea ice was 1.58m sq miles (4.1m sq km) compared with a previous low of 1.61m sq miles (4.17m sq km) on 18 September 2007.

The sea ice cap grows during the cold Arctic winters and shrinks when temperatures climb again, but over the last three decades, satellites have observed a 13% decline per decade in the summertime minimum.

The thickness of the sea ice is also declining, so overall the ice volume has fallen far - although estimates vary about the actual figure.

Joey Comiso, senior research scientist at Nasa's Goddard Space Flight Center, said this year's ice retreat was caused by previous warm years reducing the amount of perennial ice - which is more resistant to melting. It's created a self-reinforcing trend.

"Unlike 2007, temperatures were not unusually warm in the Arctic this summer. [But] we are losing the thick component of the ice cover," he said. "And if you lose [that], the ice in the summer becomes very vulnerable."

Oh dear.
I was just about to bypass this thread when I realized... nobody cares for melting ice caps in the Arctic.
It would only be when the coastal areas would start to flood that we will realize that it's too late.

Run ! Run ! Run for your lives and tell the bloody scientists to do something !!!!!!

It's not the scientist that could do something. They can just make people "aware".
It's within the power of political parties how serious they take it.

Only way they are going to take anything seriously is when it starts affecting their votebank. Nothing else can make them jump on their tows.

Guess what else increased ? My fallout character's level.

No one's could have ever guessed that!!

Yay! Waterworld XD

lets invent a freeze ray gun!!

Lets make underwater cities a la Bioshock.

Old news (!)

We are about to view yet another ATLANTIS incident!

Now soon Ramdev or someone will say its due to corruption and congress.

One reason for this could be the Global Warming and increasing Carbon footprint of the developed nations.

It is all in the hands of superpower USA as it has a major share towards greenhouse emission.
