NOAA Index Tracks How Greenhouse Gas Pollution Amplified Global Warming In 2020

NOAA Index Tracks How Greenhouse Gas Pollution Amplified Global Warming In 2020 Published: Tuesday, 25 May 2021 06:01 Methane is flared from a Bakken Field well site in North Dakota Credit: Jeff Peischl/NOAA-CIRES May 25, 2021 - Extra heat trapped in the atmosphere by human-caused greenhouse gas pollution continued to exacerbate global warming in 2020, driven by historically high emission levels that were largely unaffected by the economic slowdown stemming from the pandemic, NOAA scientists reported. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of most heat-trapping gases being added to the atmosphere principally from human activity, including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and other chemicals. The top five greenhouse gases account for about 96 percent of the increased heat trapped in the atmosphere due to human activity since 1750, the start of the Industrial Revolution. The AGGI also tr

Lightning and subvisible discharges produce molecules that clean the atmosphere -- Science & Technology -- Sott net

© Jena Jenkins Nitrogen, oxygen and water vapor molecules are broken apart by lightning and associated weaker electrical discharges, generating the reactive gases NO, O3, HO2, and the atmosphere s cleanser, OH. Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical OH and hydroperoxyl radical HO 2. The hydroxyl radical is important in the atmosphere because it initiates chemical reactions and breaks down molecules like the greenhouse gas methane. OH is the main driver of many compositional changes in the atmosphere.
