“Scientists and designers are proposing radical ways to ‘refreeze’ the Arctic”

If planting more trees can replenish forests and remove carbon dioxidefrom the atmosphere, then could we also repopulate the Arctic with ice?That’s a question posed by a team of Indonesian designers with an eye-catching response to the climate crisis: iceberg-making submarines.

“Arctic Summer Melt Shows Ice Is Disappearing Faster Than Normal”

Ice covering the Arctic Ocean reached the second-lowest level recorded for this time of year after July temperatures spiked in areas around the North Pole.

The rate of ice loss in the region is a crucial indicator for the world’s climate and a closely-watched metric by bordering nations jostling for resources and trade routes. This month’s melt is tracking close to the record set in July 2012, the Colorado-based National Snow & Ice Data Center said in a statement.

“Rise in global sea levels could have ‘profound consequences'”

Scientists believe that global sea levels could rise far more than predicted, due to accelerating melting in Greenland and Antarctica.

“How the narrative on polar bears has become a problem for Arctic environmental groups”

“When the symbol gets bigger than the region itself and people don’t realize that the polar bear is just one piece of a whole diverse web of life in the Arctic, then it can become almost a barrier.”

Russian tanker sails through Arctic without icebreaker for first time

A Russian tanker has travelled through the northern sea route in record speed and without an icebreaker escort for the first time, highlighting how climate change is opening up the high Arctic.

Receding ice decreases the Earth’s overall reflectivity, making the Arctic darker and therefore absorbing even more heat.

There’s enough water locked up in Greenland’s ice sheet to raise seas worldwide by 20 feet. While it may take centuries to fully melt, scientists are concerned that we have a limited time to act to prevent the climate from locking in the ice sheet’s demise.

“Greenland Ice Sheet Melting 600 Percent Faster Than Predicted by Current Models”

According to independent analyses by NASA, and the National Oceanic and Atmospheric Administration, Earth 2016 surface temperatures were the warmest since modern record keeping began in 1880. This makes 2016 the third year in a row to set a new record for global average surface temperatures. Heat records for the Arctic were also broken, and to a stunning degree. According to satellite data, the 2016 Arctic sea ice minimum extent, is effectively tied with 2007, for the second-lowest yearly minimum in the satellite records.

The average westerner’s carbon emissions destroy 30 square metres of Arctic sea ice every year, according to new research.

A top-secret US military project from the cold war and the toxic waste it conceals, thought to have been buried forever beneath the Greenland icecap, are likely to be uncovered by rising temperatures within decades, scientists have said.

“Anthrax Spewing Zombie Deer Are the Least of Your Warming Planet Worries”

Conditions that are melting Arctic permafrost there recently thawed the carcasses of deer felled by anthrax some 75 years ago, when World War II raged. Warmer temperatures then reactivated the infectious disease, which can survive in hibernation for decades. More than three dozen people have been hospitalized, half of them children, though with no confirmed cases. Making matters worse, a heatwave combined with the anthrax outbreak may have killed more than 1,200 deer. New ones.

As apocalyptic as this development may seem, it’s perhaps the least worrisome byproduct of warming near the top of the Earth, which is heating up the fastest. Retreating ice and softening permafrost both in the Arctic and elsewhere have already begun to yield other curiosities and dangers, some of which can do a lot more damage than a pile of dead deer.
