Warmer Arctic anticipating bird breeding
2014-07-12 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Arctic birds are nesting up to seven days earlier than usual as a result of snow melting earlier because of an increasing warmer Arctic, a new study has found. The research, published in the journal Polar Biology, suggested that clutch initiation dates for migrating Arctic birds are advancing because of climate change, which is warming up the region. Scientists from the Wildlife Conservation Society (WCS) observed 2,500 nests of four shorebird species in Alaska over a nine year period and saw nesting...

New shipping channel will carry natural gas through the Arctic

Grist: Most people think the thinning of the sea ice at the top of the world is a bad thing. But not shipping and fossil fuel interests. Shipping companies this week announced that they would use icebreakers to carve a new Arctic shipping route to help them deliver natural gas from a processing plant in western Siberia to customers in Japan and China. The Wall Street Journal reports: Once virtually impassable, the Arctic Ocean is now attracting interest as a shipping route because global warming has...

Better Understanding Arctic Climate Change Based On Shark Teeth

RedOrbit: Today, polar bears and other animals adapted to extremely cold environments inhabit the Arctic tundra. In the past, around 53 to 38 million years ago (the Eocene epoch), the Arctic was not a frozen tundra - rather, it was more like a huge temperate forest with brackish water. This forest was home to a wide variety of wildlife, including the ancestors of modern-day tapirs, hippo-like creatures, crocodiles and giant tortoises. Well-documented terrestrial deposits have given us much of our current knowledge...

Arctic warming upsetting birds' breeding calendar, study warns
2014-07-08 16:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Arctic migrants are nesting up to seven days earlier as the world warms. The sandpiper makes a beeline for the Alaskan shores, to join the phalarope on the beach and the songbirds in the woods - and all because the winter snows are melting earlier. Conservation scientists Joe Liebezeit and Steve Zack both then of the Wildlife Conservation Society (WCS) and colleagues report in the journal Polar Biology that they looked into nearly 2,500 nests of four shorebird species in Alaska two sandpipers,...

Whaling Log Books Reveal Depth of Arctic Ice Loss

Nature World: Arctic ice fronts from the early 19th century were far more advanced than they are today, according to whaling log analyses from University of Sunderland researchers, giving scientists a clue to just how much climate change is affecting this region. As part of the ARCdoc research project, scientists analyzed historical logbooks recorded by explorers, whalers and merchants during epic expeditions between 1750 and 1850, including famous voyages such as Parry's polar expedition in HMS Hecla and Sir...
