President Obama's 2016 methane waste rule, which never went into effect, required fossil fuel companies on tribal and public lands to reduce emissions of methane, a potent greenhouse gas that's about 86 times more powerful than carbon dioxide. It called on drilling operators to capture leaking and vented methane and to update their leak-detection equipment.
Scientists may need to more than double their assessment of how much carbon dioxide and methane thawing Arctic permafrost will release into the atmosphere this century, according to a study published this month.
The paper, published in Nature Communications Aug. 15, said that previous estimates for how greenhouse gasses released by thawing permafrost would contribute to global climate change focused on the slow thawing of permafrost near the surface.
A major California utility has agreed to pay nearly $120 million in a civil settlement over a huge methane leak that forced thousands to flee their homes in 2015.
The proliferation of plastic pollution has led to concerns over its impact on marine life and human health as the toxins it absorbs and emits move up the food chain. Now, a new study reveals yet another potential plastic hazard: It releases greenhouse gasses.
Over the past few months, heat records have broken worldwide.
In early July, the temperature in Ouargla, Algeria, reached 51.3°C (124.34°F), the highest ever recorded in Africa! Temperatures in the eastern and southwestern U.S. and southeastern Canada have also hit record highs. In Montreal, people sweltered under temperatures of 36.6°C (97.88°F), the highest ever recorded there, as well as record-breaking extreme midnight heat and humidity, an unpleasant experience shared by people in Ottawa. Dozens of people have died from heat-related causes in Quebec alone.

These natural processes are "positive feedbacks"—so called because they release more greenhouse gases as global temperatures rise, thus reinforcing the warming. They have previously not been represented in carbon budget estimates as they are not included in most climate models, the researchers say.

Battle lines over President Trump's nominee for a new U.S. Supreme Court justice are now being drawn, as they should be, over crucial issues such as a woman's right to choose, health care, immigration, civil rights and criminal justice. In past nomination fights, little attention has been paid to the court's role in shaping environmental law and science-based regulation. But it would be a major mistake to overlook these issues now. The Supreme Court has an enormous impact on how U.S. environmental laws are interpreted and enforced, and a new justice could tip the balance against science-based rules on climate change, clean air and clean water.
A study published Thursday found that U.S. oil and natural gas operations release 60 percent more methane than currently estimated by the U.S. Environmental Protection Agency (EPA), according to a press release from the Cooperative Institute for Research in Environmental Sciences (CIRES) at University of Colorado, Boulder.
