One solution to the melting ice cap: Refreeze it. It wouldn’t even cost that much
A record loss of Arctic sea ice and faster-than-expected melting of Greenland’s ice cap made worldwide headlines in 2012, but research published in major science journals in the fall suggest warming in the North doesn’t have to continue.
We could refreeze the Arctic, proposed a paper in Nature Climate Change. It wouldn’t even cost that much, said an affiliated study in Environmental Research Letters. The question is should we? (AP Photo/Ian Joughin; NASA)
Dinosaurs’ flatulence influenced global warming, study suggests
In a major new climate finding, researchers have calculated that dinosaur flatulence could have put enough methane into the atmosphere to warm the planet during the hot, wet Mesozoic era.
Like gigantic, long-necked, prehistoric cows, sauropod dinosaurs roamed widely around the Earth 150 million years ago, scientists reported in the journal Current Biology on Monday.
And just like big cows, their plant digestion was aided by methane-producing microbes.
“Indeed, our calculations suggest that these dinosaurs could have produced more methane than all modern sources – both natural and man-made – put together,” researcher Dave Wilkinson of Liverpool John Moores University said.
