As California’s four-year drought has drinking and groundwater reserves at dangerously low levels, households rationing water and the agricultural sector struggling to keep its crops alive, the question has been: how much of a culprit is climate change? New research published Thursday now says as much as 27 percent of the drought can be attributed to global warming.
Carbon emissions from China are 14 percent lower than previously estimated because those estimates failed to take into account the country's low quality coal that emits less carbon, according to a new study published in the journal Nature.
An ambitious new geoengineering approach promises to scrub carbon dioxide from the atmosphere and transform it into carbon nanofibers. That would turn a greenhouse gas into a highly valuable product that is stronger and lighter than steel, is used in race cars, Boeing’s new lightweight, high efficiency “Dreamliner” airplane and wind turbine blades.
A dramatic reversal of fortune for Canada's tar sands oil industry has cheered environmental advocates, and it may also leave Prime Minister Stephen Harper vulnerable in the coming federal election because of the economic repercussions, some have predicted.
The Obama administration's final approval of Royal Dutch Shell's drilling for oil in Alaska's Chukchi Sea provoked an angry reaction on Monday from environmentalists who had come to consider President Obama a champion in the fight against climate change.

The U.S. Environmental Protection Agency's first-ever proposal to reduce methane pollution, announced today, will not go far enough to reach reduction goals for the oil and gas industry, according to leading environmental organizations.
After months of strategizing in Kentucky about how the state might meet emission targets proposed under the Obama administration's power plant rules, it finds itself facing more daunting requirements under the final rule.
Coal-heavy Kentucky was initially required to reduce its carbon emissions to 77 million tons, a 15 percent reduction from 2012 levels by 2030. Under the final rules released last week, it now faces a steeper slope: reduce emissions to 63 million tons, a 30 percent cut.
As more Americans go solar—and save money on their monthly utility bills—electricity providers are doubling down on ways to protect their revenue.
One of the utilities' most widespread strategies is to impose extra charges on customers who are generating their own energy, and they have had varying degrees of success. At least 11 utilities in nine states have attempted this tactic; five have succeeded.
A federal judge rejected arguments by local Arkansas authorities that a $5 million settlement related to ExxonMobil’s 2013 pipeline rupture was too weak to protect residents and drinking water sources from another disastrous spill.
So much for the idea that American gasoline use topped out in the last decade.
Lower oil prices and the improving economy have sparked an increase in fuel use, road travel and vehicle emissions. It puts an emphatic end to the notion that better fuel economy and fewer active drivers would shrink demand for gasoline in the U.S. from what was thought to be its peak in 2007.
