    When top U.S. scientists released the fourth National Climate Assessment, it spelled out one blunt conclusion: human activity in releasing carbon dioxide into the atmosphere caused the climate change that has warmed the globe. Mandated for release every four years, the report will apparently have no sway over EPA administrator Scott Pruitt, a fossil-fuel proponent and climate-science denier. Pruitt plans to move forward in dismantling initiatives to curb CO2 production, specifically the Clean Power Act enacted by his agency under President Obama.

    Climate change all manmade, say actual scientists: awkward for Trump science deniers

    When the Environmental Protection Agency quietly issued its new four-year plan in mid-October, the phrase "climate change" did not appear anywhere in the 38-page document. It is now clear the Trump Administration intends to delay, halt, or erase government efforts to limit U.S. emissions of carbon...

    EPA to axe rule banning older, dirtier diesel engines in new trucks: report

    The EPA recently announced it will roll back the Clean Power Plan, one of former President Obama's milestone efforts to fight climate change, and now the agency plans to axe another rule limiting emissions. Next on the chopping block is a regulation that limits emissions from large trucks and their...

    Since 2007, the Renewable Fuel Standard has required increasing levels of ethanol in gasoline blends sold in the U.S. Most fuel stations across the United States no longer offer pure gasoline, with E10—a blend of 10 percent ethanol and 90 percent gasoline—prevailing. After years of debate, the EPA has now announced it will study the possibility of reducing the amount of ethanol in the U.S. gasoline supply.

  • International Paper Company mill, 1973 [From EPA Documerica series]

    It is abundantly clear that the Trump Administration does not believe in science. In its six months to date, it chose a climate-science denier to lead the Environmental Protection agency; rolled back two dozen regulations limiting air, water, and land pollution; and announced a U.S. withdrawal from the Paris Climate Agreement to limit carbon emissions. Now a new report drafted by scientists from 13 government agencies contains even grimmer news: the effects of climate change are already being felt, and it is "extremely" likely that more than half of global mean temperature increase since 1951...

    The Trump Administration has had a challenging start on numerous fronts, but its work to slash emission rules and eliminate regulations continues.
