Study finds econ costs climate change hugely underestimated

Mongabay: Look at most climate change projection graphs and you will see a smoothly rising red line of increasing temperature, melting ice and other impacts. But climate does not work that way. Studies of the paleoclimate record indicate that when heat energy is rapidly added to the atmosphere -- as humans are doing today -- the climate can experience tipping points, with abrupt shifts and potentially disastrous results. Researchers who have studied economic climate change impacts have until recently...

Climate change could disturb marine life for millennia

Agence France-Presse: Climate change may lead to disturbances in marine life that will take thousands of years to recover from, not hundreds of years as previously thought, researchers said Monday. The study in the Proceedings of the National Academy of Sciences is based on a section of fossilized ocean fauna found on the seafloor off the coast of California dating to between 3,400 and 16,100 years ago. Researchers sliced up the sediment like a cake for a before-and-after glimpse of how creatures were affected by...

Chile desert rains sign of climate change, chief weather scientist says

Reuters: The heavy rainfall that battered Chile's usually arid north this week happened because of climate change, a senior meteorologist said, as the region gradually returns to normal after rivers broke banks and villages were cut off. "For Chile, this particular system can only be possible in an environment of a changed climate," Deputy Secretary-General of the World Meteorological Organization Jeremiah Lengoasa told Reuters on a visit to Santiago on Friday. The intense rainfall that began Tuesday in...
Africa: Climate Change Cap Must be Lowered to 1.5C, Warns Expert

SciDev.Net: World leaders must reduce the long-held target of limiting global warming to below two degrees Celsius to avoid catastrophic impacts on the world's poorest people, says a leading climate scientist. Industrialised nations must stop ignoring the sustained calls from the developing world - backed by scientists - and set a 1.5 degree cap when the internationally agreed limit comes under review at UN climate talks later this year in Paris, France, says Petra Tschakert, a geographer from Pennsylvania...

Koch Money, Misleading Climate Change Exhibit Threaten Smithsonian Credibility
2015-03-23 22:00:36| Chemicals - Topix.net
The Smithsonian risks damaging its reputation by having a polluter-funded science denier on the payroll and a wildly misleading Koch-funded exhibit that downplays the risks posed by human-caused climate change. It's time for the world's self-proclaimed "largest museum and research complex," to live up to its mission - and its own climate statement - and cut ties with the anti-science, pro-pollution crowd.
