Mercury found in high levels in deep Pacific Ocean fish such as swordfish has a chemical fingerprint, and it implicates coal-burning power plants in Asia, according to a new study. A research team from the universities of Hawaii and Michigan looked at mercury in the flesh of nine species common to the massive North Pacific Subtropical Gyre, the largest ecosystem on the planet, at 7 million square miles. Four years ago, the team found that mercury levels in such fish as tuna increased with the depth of the fish's habitat.

WASHINGTON - Power plants in the United States are burning coal more often to generate electricity, reversing the growing use of natural gas and threatening to increase domestic emissions of greenhouse gases after a period of decline, according to a federal report. Coal's share of total domestic power generation in the first four months of 2013 averaged 39.5%, compared with 35.4% during the same period last year, according to the Energy Information Administration, the analytical branch of the Energy Department.

President Obama's omnibus proposal to combat global warming addresses the issue in all its many facets - truck emissions, high-level diplomacy, more federal land for solar and wind projects. Think of it as a target covered with water balloons. The president won't be able to keep all of them from bursting as his opponents in Congress and industry start throwing darts. The key is to not let them hit the bull's eye: new emissions standards for coal-fired plants. Power plants produce a third of all the greenhouse gases in the country, and coal plants are the biggest offenders.

President Obama laid out an ambitious campaign to address climate change Tuesday, mapping a course that would bypass Congress to cut emissions from hundreds of coal-fired electric power plants and setting the stage for a possible rejection of the controversial Keystone XL oil pipeline. The effort could shape Obama's presidential legacy and fulfill a key promise of his 2008 campaign. It also could plunge him into a bruising and potentially costly political battle. His plan, which relies heavily on actions the executive branch can take on its own, would put the U.S. on track to significantly cut its greenhouse gas output by the end of the decade.

WASHINGTON -- The Interior Department is losing tens of millions of dollars in revenue annually because it leases public land for coal mining at rock-bottom prices, according to a report by the agency's inspector general The report focuses on coal leases for federal and tribal lands sold by the Bureau of Land Management to mining companies. Most coal on public lands is in the Powder River Basin in Wyoming and Montana, a region that produces about 40% of the coal that the United States burns in its power plants.

POOLESVILLE, Md. - On a curve of the Potomac River 37 miles northwest of Washington, the Dickerson power plant has stood sentry over small villages, crop fields and horse farms for more than half a century. Burning mostly coal and some natural gas, Dickerson emitted about 1.5 million tons of greenhouse gases in 2011, akin to the pollution of about 275,000 cars. How much longer Dickerson will run depends in no small measure on the steps President Obama takes to fulfill the pledge he made in his State of the Union address to tackle climate change.
