Melting in the Arctic reached an all-time high in June

The ice in the Arctic has been plunging into new lows almost every month this year and last month was no different.

The amount of ice in the Arctic this June was lower than the previous all-time low in June, not only a marginal amount.

The difference in the ice from the previous low covered an area larger than the size of the UK.

From mid-June from the ice cover disappeared at an average rate of 29,000 square miles (74,000 kilometers square) a day.

How fast IT Melting?

According to figures from the US National Snow and Ice Data Center, Arctic expanse of sea ice in June 2016 averaged 10.60 million square kilometers ( 4.09 million square miles).

This was a staggering 100,000 square miles km (260,000 sq miles) below the previous record for June, which was established in 2010.

So far, March is the only month in 2016 that has not set a new record low for the Arctic to the extensive scale of the sea ice.

in March 2016 was the second lowest, just above 2015.

According to figures from the US national snow and Ice Data Center, Arctic extended sea ​​ice in June 2016 averaged 4.09 million square miles (10.6 million square kilometers).

This was 100,000 square miles (260.000 km square) below the previous record for June, which was established in 2010.

the size of the UK’s 94,058 square miles (243,610 square km).

“Until now, Mars is the only month in 2016 that has not set a new record low for Arctic-wide measure sea ice ( March 2016 was the second lowest, just above 2015). the report said.

The ice was controlled using the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on satellites Aqua and Terra NASA.

They offer multiple daily views of the Arctic, and in the summer the whole area is lit by the sun.

Although the amount of ice continued to fall to new lows, the rate is down to was lower in June than in previous months.

“slow the loss of ice in early June was the result of a significant change in atmospheric circulation,” the report said.

throughout this year, the rate of decline for the month of June was 17,200 square miles (44,600 square kilometers) a year, or 3.7 percent per decade. measure in June 2012 remained below the levels throughout the month, but it was over far 2010 for several days. 2010 had the lowest extent for several days in June

Although the sea ice cover in the Arctic is melting Antarctica has increased.

ANASA study last month said the geology of the region and the Southern Ocean are responsible for the difference.

research came to the conclusion after combining data on the surface temperature of the sea, the shape of the earth and the depth of the ocean to study physical processes sea ​​ice cover.

ice in the Arctic is melting at an alarming rate, was plunging in new lows almost every month this year, and last month was no different. The amount of ice in the Arctic this June was lower than the previous all-time low in June, not only a marginal amount

ANTARCTIC gained more ice than iT lOSES

Antarctica is gaining more ice it loses, the research by NASA found last year.

He said that the ice cap of Antarctica is thickening sufficient to offset increased losses from melting glaciers.

The research challenges the findings of other studies, including the Intergovernmental Panel on Climate Change report, which says that Antarctica is losing land ice overall.

But he also warned that losses could offset gains in future years.

increasing Antarctic snow began 10,000 years ago and continues in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7cm) per year, according to the space agency.

researchers analyzed satellite data to demonstrate the Antarctic ice sheet showed a net gain of 112 billion tons of ice annually from 1992 to 2001.

this net gain slowed to 82 billion tons of ice per year between 2003 and 2008.

They found that two geological factors persistent – the topography of Antarctica and the depth of the ocean that surrounds it – influence winds and ocean currents

This leads to the formation of the ice cover sea ​​of ​​Antarctica and helps support

“Our study provides strong evidence that the behavior of Antarctic sea ice is fully compatible with the geophysical features found in the area polar south, which strongly differ from those in the Arctic, “said Son Nghiem of the Jet Propulsion Laboratory of NASA.

Antarctic sea ice cover is dominated by first-year sea ice.

Every year, sea ice reaches its maximum extent around the frozen continent in September and pensions about 17 percent of this measure in February.

in the latest study, the research team examined the radar data QuikScat satellite of NASA 1999-2009 to trace the paths of Antarctic sea ice movements .

study found that sea ice forms and built at the beginning of the season of growth of sea ice, he pushed off and north by the winds.

This forms a protective shield of the oldest, thickest ice that circulates around the continent

Persistent winds, which flow along the slopes outside the continent and are shaped by the topography of Antarctica, shaved ice shield against the massive ice, increasing its thickness.

This strip of ice, which varies in width from about 62 to 620 miles (100 to 1,000 km), protects younger, thinner ice in the ice pack behind to be reduced by winds and waves.
