Global warming is now on its fullest and showing its presence which can be felt across
the globe. Now how much prepare you are. What are some smart ideas running in
your mind to build a safe and protective planet from this giant? What sort of
damage this relentlessly increasing warming can do to planet one can simply
imagine it and what it is going to do in its latest addition just look for it.
Sea
ice in the Arctic Ocean is likely to shrink to a record small size sometime
next week, and then keep on melting; a scientist at the US National Snow and
Ice Data Center revealed this.
“A
new daily record … would be likely by the end of August,” said Ted Scambos,
lead scientist at the data center, which monitors ice in the Arctic and
elsewhere. “Chances are it will cross the previous record while we’re still in
sea ice retreat.”
The
amount of sea ice in the Arctic is important because this region is a potent
global weather-maker, sometimes characterized as the world’s air conditioner.
As
parts of the Arctic melted, 2012 also set records for heat and drought in much
of the Northern Hemisphere temperate zone, especially the continental United
States.
This
summer could see the ice retreat to less than 1.5 million square miles (4
million square km), an unprecedented low, Scambos said.
The
previous record was set in 2007, when Arctic ice cover shrank to 1.66 million
square miles (4.28 million square km), 23 percent below the earlier record set
in 2005 and 39 percent below the long-term average from 1979 to 2000.
However,
2007 was a jaw-dropping “perfect storm” of conditions that primed the area for
thawing sea ice: warmer and sunnier than usual, with extremely warm ocean water
and winds all working together to melt the Arctic.
Last
year, Arctic sea ice extended over the second-smallest area on record, but that
was considered to be closer to a “new normal” rather than the extreme
conditions of 2007, NSIDC said then.
If
the sea ice record is broken this month, which would be unusually early in the
season; last year’s low point came on September 9, 2011.
Overall,
the decline of Arctic sea ice has happened faster than projected by the United
Nations Intergovernmental Panel on Climate Change five years ago, according to
NSIDC data.
This
summer has also seen unusual melting of the ice sheet covering Greenland, with
NASA images showing that for a few days in July, 97 percent of the northern
island’s surface was thawing. The same month also saw an iceberg twice the size
of Manhattan break free from Greenland’s Petermann Glacier.
“What you’re seeing is more Open Ocean than
you’re seeing ice,” he said. “It just simply doesn’t look like what a polar
scientist expects the arctic to look like. It’s wide open and the (ice) cap is
very small. It’s a visceral thing. You look at it and that just doesn’t look
like the Arctic Ocean anymore.”
