Scientists from NOAA, NASA and 21 universities from three countries are deploying state-of-the-art instruments in multiple, coordinated research campaigns this month to investigate how air pollution sources have shifted over recent decades. Since the 1970s, U.S. scientists and environmental regulators made significant strides in reducing air pollution by cleaning up … [continued]
A new report from CICERO finds there are unexpected negative impacts on the environment from hydrogen leakage.
20 years ago, when meteorologist John Haynes first went to Washington, DC, there was so much pollution that he could stand on the roof of NASA headquarters and see airborne residues of the neighboring interstate highway. He claims that a cloud of smog extended all the way into Virginia and … [continued]
CHICAGO, Aug. 22, 2022 — Studies have shown that pollution, whether from factories or traffic-snarled roads, disproportionately affects communities where economically disadvantaged people and Hispanic, Black and Asian people live. As technology has improved, scientists have begun documenting these disparities in detail, but information on daily variations has been lacking. … [continued]
By Kylie Foy, Massachusetts Institute of Technology, Lincoln Laboratory The 2020 Atlantic hurricane season was one of the most brutal on record, producing an unprecedented 30 named storms. What’s more, a record-tying 10 of those storms were characterized as rapidly intensifying — some throttling up by 100 miles per hour … [continued]
When lockdowns during the coronavirus pandemic cut local nitrogen oxide emissions, the effect on ozone pollution was global and unexpectedly rapid.
Humans’ combustion of fossil fuels is shrinking the stratosphere — the layer of air above the troposphere, in which we all live — illustrating the expansive nature of human impact on the planet and potentially affecting satellites and radio communications, new research shows. The study, published in Environmental Research Letters, … [continued]
ETH climate researcher Daniela Domeisen has documented how the stratosphere influences extreme weather events. What surprised her was the sheer range of potential impacts. She explains what this means for climate research and long-term weather forecasts.
New grants for the Keeling Curve and Atlantic/Pacific ocean acidification research fill in where national funding fails.
The Sentinel-6 Michael Freilich satellite will bring a new level of precision to measuring the amount and rate of sea level rise in 90% of the world’s oceans.
