Fresh Focus on Siberian Permafrost as Second Hole is Reported

2014-07-26 00:42:00| Climate Ark Climate Change & Global Warming Newsfeed

New York Times: I had a Skype chat Wednesday about Siberian permafrost in the context of climate change with Marina Leibman, a top Russian permafrost expert who had just returned from examining the unusual crater spotted on the Yamal Peninsula in Siberia late last week. We talked just before fresh reports circulated about reindeer herders finding another such hole in the region. I hope youll watch our chat, which I regret I have not yet had time to transcribe (if you are in the mood, Id be grateful for help;...

Melting permafrost and Global Warming

2014-07-19 19:10:00| Climate Ark Climate Change & Global Warming Newsfeed

Environmental News Network: The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes. The research suggests that arctic thermokarst lakes are "net climate coolers" when observed over longer, millennial, time scales. "Until now, we've only thought of thermokarst lakes as positive contributors to climate warming," said lead researcher Katey Walter...

Canada struggles with melting permafrost as climate warms

Scientific American: In 2006, reduced thickness of ice roads forced the Diavik Diamond Mine in Northern Canada to fly in fuel rather than try to transport cargo across melted pathways, at an extra cost of $11.25 million. The mountain pine beetle outbreak in British Columbia--fueled by higher winter temperatures that allow insects to survive--expanded in recent years to be 10 times greater than any previously recorded outbreak in the province. Mortality rates of sockeye salmon, meanwhile, have increased because of...

Alaska Public Media: Scientists are announcing a surprising find from the arctic: new permafrost is still forming. But it is unlikely to survive beyond the end of the century. Thats according to a new study out this week in the publication Geophysical Research Letters. Researchers made the discovery at a lake in Alaskas Eastern Interior. Twelvemile Lake, southwest of Fort Yukon is disappearing. Over the last three decades, scientists say the lake has lost 15 feet of water. Across the arctic, theres a lot of...

Softpedia: Study finds a new permafrost is now in the making in Alaska Except for people who live in smack in the middle of nowhere and folks who choose to remain oblivious to what is happening to the world around them, pretty much everybody knows that climate change is reshaping our planet's ecosystems. Writing in the journal Geophysical Research Letters, scientists with McGill University and the United States Geological Survey explain that this man-made phenomenon is now cooking up a new permafrost in...
