Scientists: Current International Warming Target Is Disastrous
2013-12-04 16:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Desk: Ever since the 2009 climate talks in Copenhagen, world leaders have agreed on 2 degrees Celsius (3.6 degrees F) as the maximum acceptable global warming above preindustrial levels to avert the worst impacts of climate change (today we`re at about 0.8 degrees C). But a new study, led by climatologist James Hansen of Columbia University, argues that pollution plans aimed at that target would still result in "disastrous consequences," from rampant sea level rise to widespread extinction. A major...

Climate change inaction betrays the next generation, scientists warn

PhysOrg: Most of the Earth's remaining fossil fuels must be left in the ground to avoid disastrous consequences for today's young people and for future generations, according to research published today. The research is co-authored by 18 scientists from around the world, including University of Queensland Global Change Institute Director Professor Ove Hoegh-Guldberg. The research was led by former NASA Goddard Institute for Space Studies Director Dr James Hansen, and is published in the Plos One journal....

Dangerous Global Warming Closer than You Think, Climate Scientists Say
2013-12-04 12:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Abrupt climate change is not only imminent, it's already here. The rapid dwindling of summer Arctic sea ice has outpaced all scientific projections, which will have impacts on everything from atmospheric circulation to global shipping. And plants, animals and other species are already struggling to keep up with rapid climate shifts, increasing the risk of mass extinction that would rival the end of the dinosaurs. So warns a new report from the U.S. National Research Council. That's exactly why longtime...

Scientists want global monitoring to warn of climate change impacts
2013-12-04 01:13:00| Climate Ark Climate Change & Global Warming Newsfeed
Denver Post: Government-backed U.S. scientists on Tuesday urged for the creation of a warning system to help people anticipate the impact of climate change on food, water and cities. Early warnings would give more time to adapt, but they will require much closer monitoring of warming oceans, increasing greenhouse gas emissions, and extinctions of plants and animals, according to the scientists and a report unveiled by a National Research Council committee. There are too many blind spots to be able to anticipate...
