Camden, NJ, United States (4E) – The melting of Greenland’s massive ice sheet is off the charts.

A new study proves the melting of ice in this massive island has vastly accelerated and shows no signs of tapering-off.

“Melting of the Greenland ice sheet has gone into overdrive,” said Luke Trusel, a glaciologist at Rowan University and lead author of the study. “Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years.”

The published study found that Greenland’s ice loss has accelerated rapidly over the past two decades after remaining relatively stable since the dawn of the Industrial Revolution in the mid-1800s.

Greenland’s ice sheets are now melting at a rate 50% higher than pre-industrial levels and 33% above 20th-century levels, said the study.”What we were able to show is that the melting that Greenland is experiencing today is really unprecedented and off the charts in the longer-term context,” said Sarah Das, an associate scientist at the Woods Hole Oceanographic Institution and a co-author of the study.

Scientists affirm ice loss from Greenland is the single largest cause to global sea-level rise. This rise is predicted to result in the inundation of low-lying islands and coastal cities around the world.

Conservative estimates see global sea level rise adding half a meter or more by 2100 . Experts saud half a meter is “a terrible disaster for humanity – especially coastal regions of the planet.”

Eight of the 10 largest cities in the world are near coasts. Some 40% to 50% of the global population lives in coastal areas vulnerable to sea-level rise.

“From a historical perspective, today’s melt rates are off the charts, and this study provides the evidence to prove this” said co-author Sarah Das. In just one year (2012), enough ice melted into water to fill up about 240 million Olympic swimming pools.

Antarctica’s Ice Melt has Sped-up by 280%, Stoking Sea-Level Rise

The rate of the ice melting in Antarctica has accelerated by an unacceptable 280% over the last four decades, setting the stage for catastrophic sea-level rise in the future.

Oakland, CA, United States (4E) – The rate of the ice melting in Antarctica has accelerated by an unacceptable 280% over the last four decades, setting the stage for catastrophic sea-level rise in the future.

Two new studies released tell the same foreboding message — our planet’s ice is melting at a frightening rate. The first harmful effect of this dangerous development: higher sea-level rise.

Ice loss in Antarctica increased from 40 gigatons (or one billion tons) per year from 1979 to 1990 all the way up to 252 gigatons per year from 2009 to 2017, a six-fold increase. This published study led by the University of California (UC) also found the melt-rate has accelerated in the most recent decades. The melt rate hit 280% in the second half of the nearly 40 years compared to the first half.

Antarctica’s crucial ice sheet has been melting for the entire 39 year period, but this is just the tip of the iceberg, so to speak, said Eric Rignot, who led the UCV study.

“Antarctica is melting away,” said Rignot, (and) “not just in a couple of places.”

Antarctica holds most of the Earth’s ice. If melted, the Antarctic ice will cause the average sea level to rise 57.2 meters or 188 feet.

Another alarming finding in the study is that East Antarctica has seen a lot of melting over the same 39 year period. This challenges the traditional scientific view the East Antarctic ice sheet is relatively stable and resistant to change. The study also confirms the West Antarctic ice sheet accounts for most of the recent ice loss.

“I did not expect the cumulative contribution of East Antarctica melt to be so large,” said Rignot.

He noted the finding is significant because “melting is taking place in the most vulnerable parts of Antarctica…parts that hold the potential for multiple meters of sea level rise in the coming century or two.”

Another published study compared the geologic record of Antarctica’s ice with the known astronomical motions of the planet and the wobbling of the Earth’s tilt.

Researchers were able to re-create a broad history of the Antarctic ice sheet going back 34 million years to when the ice sheet first formed. They documented multiple cycles of ice growth and decay.

The study said that some 15 million years ago, when Earth’s atmosphere was supercharged with carbon dioxide, oceans warmed and sea ice around Antarctica disappeared. This event caused a significant part of the Antarctic ice cap to melt and dramatically elevate global sea levels.

“What this study does is characterize the growth and decay of the Antarctic ice sheet and sheds light on what is forcing it to change,” explains Stephen Meyers of the University of Wisconsin-Madison, one of the study’s co-authors along with Richard Levy of New Zealand’s GNS Science and Victoria University of Wellington.

Levy and Meyers found that sea ice, or the thin frozen layer of ocean water that surrounds Antarctica, plays a critical role in protecting the miles-deep ice on the continent from the warmer ocean that surrounds it.

“Sea ice creates a barrier between the ocean and the ice,” said Levy.

Fight vs Climate Change Given Teeth with New Rules

Katowice, Poland (4E) – The rules that will implement the 2015 Paris Agreement have been approved by nearly 200 countries following a contentious and sometimes rowdy series of meetings in Katowice, Poland.

United Nations’ member countries party to the 2018 United Nations Climate Change Conference will implement the new rules in 2020. The new rules are detailed in a 156-page rulebook broken down into themes. These themes include how countries will report and monitor their national pledges to curb greenhouse gas (GhG) emissions and update their emissions plans.

The 2018 United Nations Climate Change Conference is the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24). It’s informally known as the Katowice Climate Change Conference and was held from Dec. 2 to 15. It was held to give flesh to the Paris Agreement.

The Paris Agreement’s long-term goal is to keep the increase in global average temperature to well below 2°C (3.6 degrees Fahrenheit) above pre-industrial levels. It also seeks to limit the increase to 1.5°C since this level will greatly reduce the risks and effects of climate change.

Proponents of the new rules consider them a good foundation for countries to go about implementing the Paris Agreement.

“It is not easy to find agreement on a deal so specific and technical,” said Michal Kurtyka, the Polish president of the talks. “Through this package you have made a thousand little steps forward together. You can feel proud.”

Before the Katowice talks began, many expected the deal might not be as robust as it needed to be. The unity palpable at the Paris talks has weakened, mainly due to Trump’s ignorant opposition to the existence of climate change and global warming.

One of the talk’s leaders complained about the fact countries had to be dragged kicking and screaming to the finish line. He said this shows that some nations — especially Trump’s America — have not woken up to the urgent call of the report by the International Panel on Climate Change (IPCC).

The IPCC in October warned that keeping the Earth’s temperature rise to 1.5C will need “unprecedented changes” in every aspect of society.

Northwest Territorries, Canada (4E) – The largest diamond ever discovered in North America — a gem weighing-in at 552 carats – was recently unearthed in Canada.

Canadian mining company Dominion Diamond Mines said the yellow diamond was unearthed in October at the Diavik Diamond Mine located in Northern Canada about 135 miles south of the Arctic Circle.

This still unnamed diamond, which is about the size of a chicken egg, is the seventh-biggest this century. Dominion Diamond Mines called the gemstone “astonishing.”

The company said abrasion markings on the surface of the 552 carat gemstone attest to the difficult journey it underwent during recovery, and the fact that it remains intact is remarkable.

Dominion CEO Shane Durgin said the diamond is gem quality. This means the gemstone is suitable for jewelry.

Since it’s still being evaluated, this diamond’s ultimate worth hasn’t been determined. It will not be sold in its rough form and will be polished to ramp-up its value.

The 552 carat gem is almost three times the size of the Diavik Foxfire, which is next largest stone ever found in Canada. Diavik Foxfire is a 187.7 carat gem-quality diamond unearthed in the same mine by the Rio Tinto Group.

it was later turned into a pair of yellow earrings, which sold for more than $1.5 million. That stone is about one-third the weight of this new diamond.

Yellow stones typically sell at a discount to Type IIa top whites often found in the best African mines. The highest quality fancy vivid yellow or fancy intense yellow stones can sell for a premium.

In 2015, a 1,111 carat diamond was discovered at a mine in Botswana. The size of a human palm, it came second to only the 3,106 carat Cullinan diamond, which was found in 1905 in South Africa.
