Bad news: Scientists say we could be underestimating Arctic methane emissions
2015-12-22 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Arctic permafrost has become a recent star in the climate change conversation, capturing the attention of scientists, activists and policymakers alike because of its ability to emit large quantities of carbon dioxide as well as methane a particularly potent though relatively short-lived greenhouse gas when it thaws. As temperatures rise in the Arctic, scientists are increasingly concerned that permafrost will become a major contributor to the greenhouse gas emissions driving global warming. ...

Japan to Consider Emissions Trading in Climate Change Plan
2015-12-21 23:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: Japan may consider introducing national-emissions trading as part of a set of measures it intends to put together by early next year to tackle climate change. The government will compile the climate change plan to fulfill its pledge to reduce emissions by 26 percent by 2030 from 2013 levels, according to a statement issued Tuesday. The pledge was made earlier this year to the United Nations. Two government panels -- one set up by the Ministry of Economy, Trade and Industry and another by the...

Greenhouse gas emissions from freshwater higher than thought
2015-12-21 16:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Do not underestimate the babbling brook. When it comes to greenhouse gases, these bucolic water bodies have the potential to create a lot of hot air. According to a new analysis in the journal Ecological Monographs, by researchers at the University of WisconsinMadison and colleagues, the worlds rivers and streams pump about 10 times more methane into our atmosphere than scientists estimated in previous studies. The new study also found that human activity seems to drive which streams are the...

Greenhouse gas emissions from Canadian Arctic aquatic systems dated for the first time
2015-12-19 06:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: For the first time, researchers have successfully dated the carbon dioxide (CO2) and methane (CH4) emitted by ponds and lakes on Bylot Island, Nunavut. The research team observed significant variability in age and emission rates of greenhouse gases (GHG) from aquatic systems located in a continuous permafrost zone. The study, whose lead author is Frédéric Bouchard affiliated to the INRS Eau Terre Environnement Research Centre and the Geography Department of Université de Montréal, appeared in the...
