15 February 2018 (EDF) – Methane emissions from Pennsylvania’s oil and gas sites may be more than five times higher than what oil and gas companies report to the Pennsylvania Department of Environmental Protection (DEP), according to a new analysis from Environmental Defense Fund.Methane is both a powerful climate pollutant and the primary ingredient of […]
15 February 2018 (NOAA) – Emissions from volatile chemical products like perfumes, paints and other scented consumer items now rival vehicles as a pollution source in greater Los Angeles, according to a surprising new NOAA-led study.Even though 15 times more petroleum is consumed as fuel than is used as ingredients in industrial and consumer products, […]
By Hayley Dunning 6 February 2018 (Imperial College London) – The ozone layer is recovering at the poles, but unexpected decreases in part of the atmosphere may be preventing recovery at lower latitudes.

The letter listed environmental impacts like they were biblical […]
By Sam Lemonick 17 October 2017 (Forbes) – A years-long study of Minnesota farm fields has found that emissions of nitrous oxide—a more dangerous greenhouse gas than carbon dioxide—will likely increase as our planet gets warmer. And our climate models aren’t ready.Like carbon dioxide, nitrous oxide (yes, the same stuff as laughing gas) traps heat […]
By Bob Henson 3 September 2017 (Weather Underground) – The steamy, fiery summer of 2017 hit a new crescendo this weekend across the U.S. West, which is getting its hottest Labor Day weekend on record in many locations—and in some spots, the hottest weather ever observed.
