Keystone XL pipeline may create more pollution than previously calculated

Agence France-Presse: A proposed pipeline from Canada to the United States may result in much higher greenhouse gas emissions than previously calculated as it could fuel greater oil consumption through higher production and lower prices, a study said Sunday. Researchers from the Stockholm Environment Institute used a mathematical model to estimate the Keystone XL pipelines potential for atmospheric pollution. Unlike calculations by the US State Department, they took into account a possible consumption rise in line...

Wildfires Play Bigger Role in Climate Change than Previously Thought

2014-08-04 22:04:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: Wildfires and other types of fires involving plant matter play a much bigger role in climate change and human health than previously thought, according to a recent study. Scientists have long known that biomass burning - burning forests to create agricultural lands, burning savannah as a ritual, slash-and-burn agriculture and wildfires - figures into climate change and public health. But this study, published in the Journal of Geophysical Research: Atmospheres, is the first to measure the degree...

Wildfires And 'Biomass Burning' Bigger Climate Change Threats Than Previously Thought

2014-08-01 19:59:00| Climate Ark Climate Change & Global Warming Newsfeed

Business Times: Nearly one-fifth of the carbon dioxide emissions caused by humans can be traced back to wildfires, slash-and-burn agriculture and the burning of wood waste to produce power, a Stanford University report found. While biomass burning has long been considered a culprit of climate change, the new research is the first to comprehensively quantify that threat -- and the number suggests the risks may be higher than previously thought. About 18 percent of all human-made carbon dioxide emissions -- or...

Climate Change A Greater Threat To Global Food Production Than Previously Thought: MIT Researchers

Business Times: Climate change could pose an even greater threat to global food production than previously thought, according to new research. Rising temperatures will not only damage heat-sensitive crops theyll also increase toxic air pollution, which will harm crops even further. The study, out this week in the journal Nature Climate Change, is the first to explore how this interaction between warming temperatures and air pollution affects staple crops. Scientists have long known that the two can independently...
