Climate warming may not drive net losses soil carbon from tropical forests
2014-07-28 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous release of carbon is balanced by carbon coming into the soil system from falling leaves and other plant matter, as well as by the underground activities of plant roots. Short-term warming studies have documented that rising temperatures increase the rate of soil respiration. As...

Warming Threatens Roads, Ports and Planes, Report Says
2014-07-28 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The transportation sector is a major contributor to climate-changing carbon dioxide emissions, and, worldwide, it's also one of the most vulnerable sectors to the effects of climate change, according to a new report. In other words, climate change could mean "sun kinks' could warp train tracks in the heat, airplanes will be more expensive to fly, highway surfaces could soften in heat waves, roadways and bridges could be washed away in rising seas and storm surges, and storms in the open ocean...

New study confirms water vapor as global warming amplifier
2014-07-28 15:54:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere - a key amplifier of global warming - will intensify climate change impacts over the next decades. The new study is the first to show that increased water vapor concentrations in the atmosphere are a direct result of human activities. "The study is the first to confirm that human activities have increased water...

5 facts about coal trade, global warming
2014-07-27 22:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: As the Obama administration weans the U.S. off polluting fuels blamed for global warming, energy companies have been sending more of America's unwanted energy leftovers to other parts of the world where they could create even more pollution. Here are five things to know about the issue: As U.S. reduces coal use, demand rises globally Over the past six years, the U.S. has cut consumption by 195 million tons as power plants have burned cheaper natural gas instead. The Environmental Protection...

Scientists Identify Possible 'Tipping Point' of Global Warming
2014-07-24 22:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Scientists have long been concerned that global warming may push the Earth's climate system past a "tipping point," and a new study from Oregon State University (OSU) may have finally identified that threshold. According to the research, synchronization of climate variability in the North Pacific and North Atlantic Oceans is that tipping point - where rapid melting of ice and further warming may become irreversible. This is what happened a few hundred years before the rapid warming that took place...
