The Doomsday Glacier - Rolling Stone. In the farthest reaches of Antarctica, a nightmare scenario of crumbling ice – and rapidly rising seas – could spell disaster for a warming planet.
Thwaites Glacier in West Antarctica is so remote that only 28 human beings have ever set foot on it. Knut Christianson, a 33-year-old glaciologist at the University of Washington, has been there twice. A few years ago, Christianson and a team of seven scientists traveled more than 1,000 miles from McMurdo Station, the main research base in Antarctica, to spend six weeks on Thwaites, traversing along the flat, featureless prairie of snow and ice in six snowmobiles and two Tucker Sno-Cats. "You feel very alone out there," Christianson says.
Future - How Western civilisation could collapse. The political economist Benjamin Friedman once compared modern Western society to a stable bicycle whose wheels are kept spinning by economic growth.
Should that forward-propelling motion slow or cease, the pillars that define our society – democracy, individual liberties, social tolerance and more – would begin to teeter. Our world would become an increasingly ugly place, one defined by a scramble over limited resources and a rejection of anyone outside of our immediate group. Should we find no way to get the wheels back in motion, we’d eventually face total societal collapse. Scientists to EPA head: You don’t know what you’re talking about. Last week, newly appointed EPA head Scott Pruitt made some comments about climate change that were clearly at odds with a basic scientific understanding of the climate.
Since then, various groups of scientists have pointed out just how wrong he was and have offered to help out if he decides to come to grips with reality. Super-warm seas wiped out an entire underwater forest in Australia, scientists report. This year, the tragic die-off of large volumes of coral at the treasured Great Barrier Reef has provided a climate change shock like few others.
The cause was too much warm water — which seems to have pushed the corals past a thermal survival threshold. And that warm water, in turn, is tied to climate change. Now, however, a team of researchers has revealed that another Australian coastal ecosystem that gets less attention — Australia’s kelp-dominated Great Southern Reef, which covers a huge expanse along its more temperate southern and southwestern coast — saw an equally dramatic ecosystem upheaval five years ago. New Study indicates Sea Level Rise is a Bigger Problem than Previously Estimated. Humans are being wide off the mark regarding severity of global sea level rise, said a team of researchers in a new study published this week in the journal Atmospheric Chemistry and Physics.
The study team informed that the planet could experience much more rise in sea levels than previously estimated, thanks to climate change which is going to worsen in the future. The research team said that 2 degree Celsius target set by climate scientists and policymaker isn’t enough. Several nations around the globe have pledged to curb greenhouse gas emissions and limit planet’s warming to 2 degrees Celsius by the next century, but these efforts are not sufficient to control sea level rise, suggested the study published in the journal Atmospheric Chemistry and Physics. “We are in a position of potentially causing irreparable harm to our children, grandchildren and future generations. This is a complex story, but one with important practical implications”, as per Hansen.
Massive fossil fuels cut is last chance to limit global warming, researchers say. The Point of No Return: Climate Change Nightmares Are Already Here. Historians may look to 2015 as the year when shit really started hitting the fan. Some snapshots: In just the past few months, record-setting heat waves in Pakistan and India each killed more than 1,000 people. In Washington state's Olympic National Park, the rainforest caught fire for the first time in living memory. London reached 98 degrees Fahrenheit during the hottest July day ever recorded in the U.K.; The Guardian briefly had to pause its live blog of the heat wave because its computer servers overheated.
In California, suffering from its worst drought in a millennium, a 50-acre brush fire swelled seventyfold in a matter of hours, jumping across the I-15 freeway during rush-hour traffic. Then, a few days later, the region was pounded by intense, virtually unheard-of summer rains. Hansen's new study also shows how complicated and unpredictable climate change can be.

When people burn fossil fuels or clear forests today, the extra carbon we put in the atmosphere stays long enough to add to global warming for thousands of years. Warming won’t just stop when we stop polluting, and neither will sea level rise. The Big Read: Climate change and the fate of Antarctica. A world-renowned climate scientist visiting New Zealand will this week present new evidence suggesting a behemoth "sleeping giant" ice sheet is more sensitive to climate change than we ever thought.
To climate scientists, the vast East Antarctic Ice Sheet represents something of the elephant in the room in terms of what it could contribute to global sea level rise. If all of it melted, the ice sheet, which forms most of Antarctica, would contribute an equivalent of around 50 metres of sea level rise - the vast majority of the total 58 metres that could come from the frozen continent. The part of the ice sheet that rests on bedrock below sea level is most vulnerable and holds an equivalent of 19 metres of sea level rise.
