Antarctica could be much more vulnerable to melting than we thought

Washington Post: In two new studies, scientists say that the vast ice continent of Antarctica seems to have given up tremendous volumes of ice -- even sprouting considerable plant life -- during an era over 10 million years ago when concentrations of atmospheric carbon dioxide dont seem to have been all that much higher than they are now. That period was known as the Miocene. And during its early and middle phases, between 23 and 14 million years ago, carbon dioxide concentrations are believed to have sometimes...

Charging electric vehicles at night can cause more harm than good, says study

ScienceDaily: Researchers at Carnegie Mellon University find that while charging electric vehicles at night is more cost-effective, it increases air emissions. Charging electric vehicles late at night, when demand is low and electricity is cheapest to generate, is preferred by grid operators. However, CMU researchers found that it produces substantially higher greenhouse gas emissions and air pollution than simply charging as soon as the driver returns home.

Antarctic ice sheet is more vulnerable to carbon dioxide than expected
2016-02-23 01:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Results from a new climate reconstruction of how Antarctica's ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two papers in the current Proceedings of the National Academy of Sciences. Researchers led by Edward Gasson and...
