UK faces food security catastrophe as honeybee numbers fall, scientists warn
2014-01-08 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The UK faces a food security catastrophe because of its very low numbers of honeybee colonies, which provide an essential service in pollinating many crops, scientists warned on Wednesday. New research reveals that honeybees provide just a quarter of the pollination needed in the UK, the second lowest level among 41 European countries. Furthermore, the controversial rise of biofuels in Europe is driving up the need for pollination five times faster than the rise in honeybee numbers. The research...

U.S. polar vortex brings Big Chill to forest pests: scientists
2014-01-08 19:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The record cold U.S. temperatures may have a silver lining - killing off some tree-eating forest pests that have spread dangerously as the general climate warms up, scientists said. The deep freeze that shattered decades-old records this week - causing fatalities and snarling air, road and rail traffic - could adversely affect pests such as the emerald ash bore, which is responsible for killing more than 10 million trees, said Robert Venette, a research biologist with the U.S. Forest Service in...

Climate Change Can Be Mitigated By Reducing Demand On Livestock, Scientists Say
2014-01-05 23:22:00| Climate Ark Climate Change & Global Warming Newsfeed
International Business Times: If climatologists had their way, wed be living on a diet of nuts and grains instead of beef and pork. Their reasoning? Livestock and the methane they produce are a major source of greenhouse-gas emissions around the globe. And now more than ever, many scientists are arguing for us to reduce our reliance on livestock to mitigate the effects of global warming. A new study published Dec. 20 in the journal Nature Climate Change makes the case for cutting back on our consumption of meat from cows,...

Back to the future: Scientists search the internet for evidence of time travelers
2014-01-02 17:31:11| Extremetech
If you were to ask 100 people to pick the single greatest superhero power or sci-fi technology, time travel would almost certainly win. And believe it or not, time travel isn't entirely outside the realm of reality -- for some unified theories of the universe, such as general relativity, traveling in time is actually fairly easy. That's why two American researchers have started searching the internet for evidence of time travelers.

Planet likely to warm by 4C by 2100 scientists warn
2013-12-31 15:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Temperature rises resulting from unchecked climate change will be at the severe end of those projected, according to a new scientific study. The scientist leading the research said that unless emissions of greenhouse gases were cut, the planet would heat up by a minimum of 4C by 2100, twice the level the world's governments deem dangerous. The research indicates that fewer clouds form as the planet warms, meaning less sunlight is reflected back into space, driving temperatures up further still....
