Arctic thaw significantly worsens global warming risk

2014-02-18 19:55:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: Melting ice is cooking the planet. Shrinking Arctic sea ice means the ocean is absorbing more energy from the sun, and it's now clear the effect is twice as big as thought - adding significantly to heating from greenhouse gases. Arctic temperatures have risen 2 °C since the 1970s, leading to a 40 per cent dip in the minimum summer ice coverage in the Arctic Ocean. Open water soaks up more sunlight than ice, so as the ice retreats the ocean absorbs more energy, warming it and causing even more...

Darker Arctic boosting global warming

2014-02-17 22:52:00| Climate Ark Climate Change & Global Warming Newsfeed

Associated Press: The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says. With more dark, open water in the summer, less of the sun's heat is reflected back into space. So the entire Earth is absorbing more heat than expected, according to a study published Monday in the Proceedings of the National Academy of Sciences. Melting Arctic ice called economic time bomb That extra absorbed energy is so...

Global Warming Pushes Native Plants to New Habitats Leaving Dependent Species at Risk

Climate News: By 2100, vegetation patterns will be shifting in almost half the land area of the planet, according to new research in the journal Global and Planetary Change. Song Feng of the University of Arkansas in the U.S. and colleagues in Nebraska, China and South Korea have taken a long cool look at what the projected patterns of warming are likely to do to the planets mosaic of climate types. And they predict dramatic changes. Climate type is a century-old idea useful for making sense of geographical...

Global warming: Warning against abrupt stop geoengineering method

2014-02-17 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions. The new study, published today, 18 February, in IOP Publishing's journal Environmental Research Letters, has highlighted the risks of large...

If there is global warming this is what it could look like in Britain

Telegraph: It is an all too familiar sight these days as Father Thames reclaims his ancient sovereignty over his flood plain. A street, in Oxford, has become a river, banked by sodden suburban homes. Its inhabitants have taken to canoes instead of cars. But this time there is something else: people are holding a banner: "Can we talk about climate change now?' Well, I guess they can. At first, the possibility that global warming might have something to do with the extraordinary weather -- which has dumped...
