The IceBridge scientists measured the Larsen C fracture to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. The crack completely cuts through the ice shelf but it does not go all the way across it ā once it does, it will produce an iceberg roughly the size of the state of Delaware
An Ice Shelf Twice the Size of Manhattan Is About to Break Off From Antarctica
The good news is that ice shelves don't produce sea level rise just by breaking away - they're already floating ice shelves that are simply attached to the perimeter of Antarctica. But the bad news is that, when they're attached, they slow down ice loss from the centre of the continent, and when that process speeds up, it does contribute to sea level rise.
Starvation killed 80,000 reindeer after unusual Arctic rains cut off the animalsā food supply
Reindeer can stamp through ice about three-quarters of an inch thick, using their feet to access the nutritious lichen and plants below. But in early November 2006 and 2013, the ice was an order of magnitude deeper ā up to several inches, too tough even for the reindeerās sharp hoofs. Unable to eat, the animals died
āAs the relatively warm water becomes exposed, vapor forms and air humidity increases,ā Forbes said. āThe more extensive the open water (or with jumbled, fractured ice in loose concentrations), the more moisture available to increase atmospheric humidity.ā
And with that wetter air comes rain.
1,500 reindeer dead, 40 humans hospitalized amid anthrax outbreak in Siberia | VICE News
At least 40 people from nomadic communities in northern Siberia have been hospitalized amid an anthrax outbreak that scientists believe was caused by thawing reindeer carcasses.
Northern Siberia has been hit with a bout of weird weather, including a heatwave that has led to record-high temperatures. In the Yamal tundra, which sits above the Arctic Circle, temperatures soared to 95 degrees Fahrenheit, compared to the average of 77 degrees this time of the year. Scientists have linked the heatwave to climate change.
First Mammal Declared Extinct Due to Climate Change, Scientists Say
Coral with leaves: Millions of trees join the list of climate change casualties
Just a few years after mountain pine beetles killed millions of acres of lodgepole pine forests in the Rocky Mountains, the U.S. Forest Service is reporting widespread tree deaths in drought-hammered Southern California. Even Europe's cool, moist forests have been losing trees at a fast rate. Large-scale simultaneous forest loss on different continents could have an impact on forests' ability to absorb atmospheric carbon, scientists say.
Scientists have increasingly linked forest mortality with climate impactsāand in Southern California, it is most directly tied to a steady increase in droughts that weaken trees, making them more susceptible to pine beetles. A 2015 study in the journal Geophysical Research Letters found that human-caused warming "substantially increased the overall likelihood of extreme California droughts."

In a way, I'm glad I'm old. I won't see the disaster that's coming to the planet. Just when things are passing a tipping point, ignorant right wingers all over the world are taking power. The evidence is right there. Right in front of us. It's not that right wingers don't see it. It's they refuse to see it. A true determined ignorance.
It's like the right wing with Donald Trump. So sure he is going to bring them high paying jobs requiring no skills or education. Who could believe something so ridiculous? Unfortunately, half of America believes it.
