'Ice age blob' of warm ocean water discovered south of Greenland
2016-02-19 23:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: New research published in Scientific Reports in February indicates that a warm ocean surface water prevailed during the last ice age, sandwiched between two major ice sheets just south of Greenland. Extreme climate changes in the past Ice core records show that Greenland went through 25 extreme and abrupt climate changes during the last ice age some 20,000 to 70,000 years ago. In less than 50 years the air temperatures over Greenland could increase by 10 to 15 °C. However the warm periods were...
Arctic Sea Ice Is in Record Low Territory (Again)
2016-02-19 01:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The winter of discontent in the northern latitudes continues. Persistent warmth has baked the region, making snow a no show in parts of Alaska and, perhaps more importantly, slowing the growth of Arctic sea ice. Though it's still likely a month before the Arctic sea ice reaches its maximum, the current trajectory is not a good one. Slow and at times non-existent growth has already led to a record low January extent and preliminary data from February indicate sea ice continues to set daily record...
Are ice streams contributing to the rise of ocean levels?
2016-02-18 12:36:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: A study released Wednesday in the journal Nature suggests that the recent thinning behavior of ice streams in some of the world's largest glaciers may not point to as grim a climate scenario as was once thought. Ice streams, or fast-moving regions of massive ice sheets glaciers larger than 19,000 square miles have become a cause for concern in recent years as their retreat in the world's only major ice sheets in Greenland and Antarctic has been linked to sea level rise. But the new study may...
New study is 'a leap forward' in our understanding of ice sheet behavior
2016-02-17 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: In recent years, climate scientists have grown increasingly concerned that massive rivers of ice flowing into the ocean from Greenland and Antarctica could accelerate as the planet warms, leading to a catastrophic collapse of Earth's ice sheets. This grim scenario would cause the world's oceans to rise rapidly, putting many island nations and coastal communities around the world under water. But a new paper in Nature by C.R. Stokes and colleagues presents an alternative narrative of the manner...

Which compact SUV has the best all-wheel-drive system for snow and ice?
2016-02-16 18:17:27| Extremetech
When there's a foot of snow on the ground in Colorado, winter tires make perfect sense. They probably make sense in milder climates, especially if you have summer tires that become useless below freezing.
