A warming trend has contributed to a sharp rise in the number and size of wildfires on forest lands in the U.S. West, where big burns are likely to become the norm, according to a report released by a climate research group. The average annual number of fires that cover more than 1,000 acres has…
Ocean temperatures off the northeast United States have reached a record high. The National Oceanic and Atmospheric Administration reported that the average sea surface temperature for the Northeast continental shelf ecosystem, from North Carolina to Maine, was a little over 50.5 degrees for the first half of 2012. The previous record high for the first…
With Arctic ice melting at record pace, the world’s superpowers are increasingly jockeying for political influence and economic position in outposts previously regarded as barren wastelands. At stake are the Arctic’s abundant supplies of oil, gas and minerals that are, thanks to climate change, becoming newly accessible along with increasingly navigable polar shipping shortcuts. This…
Mitt Romney’s remarks on NBC’s Meet the Press in early September rankled environmental activists hoping for a bipartisan approach to climate change. “I’m not in this race to slow the rise of the oceans or to heal the planet,” the Republican presidential nominee told David Gregory. “I’m in this race to help the American people.”…
One of the world’s leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years. In what he calls a “global disaster” now unfolding in northern latitudes as the sea area that freezes and melts each year shrinks to its lowest extent ever recorded, Prof Peter Wadhams of…
Researchers have made a startling discovery: the summer Arctic could be an open sea within a decade
The chance to save the world’s coral reefs from damage caused by climate change is dwindling as man-made greenhouse gas emissions continue to rise, scientists said in a study released on Sunday. Around 70% of corals are expected to suffer from long-term degradation by 2030, even if strict emission cuts are enforced, according to the…
Every time a new sea ice extent record for Arctic melting is broken, the same question comes up: how long until it’s gone? That is, how long will it be before the Arctic Ocean is functionally ice-free in the summer, legitimately opening the once-fabled Northwest Passage? The fact is, we don’t know. Climate models continue…
The loss of Arctic ice is massively compounding the effects of greenhouse gas emissions, ice scientist Professor Peter Wadhams has told BBC Newsnight. White ice reflects more sunlight than open water, acting like a parasol. Melting of white Arctic ice, currently at its lowest level in recent history, is causing more absorption. Prof Wadhams calculates…
A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable. Published in IOP Publishing’s journal Environmental Research Letters, the study has shown that the basic technology…
