EarthSky had an interesting article this week on the uptick in global methane levels in recent years after “flat-lining” from 1999 to 2006. The article gives an excellent discussion of where the methane comes from, including natural wetlands and agricultural production, and looks at how it is changing by latitude and how that can help…

Eos had an interesting article this week about how turbulent pockets of air inside of thunderstorms can help set up the conditions necessarily for lightning, a new finding published recently in Journal of Geophysics: Atmospheres. The new study shows that the bumpy air not only caused your plane to jump up and down but can…

After the 4th of July fireworks across the country were over, meteorologists turned to their observations to see what effects the smoke and particulates from the fireworks had on air quality in the areas downwind of the displays. What they showed were that the level of dangerous aerosols increased immediately after the fireworks started and…

Late in June the New York Times reported that scientists measuring the carbon dioxide of the atmosphere have found a troubling trend–even though emissions of CO2 have leveled off globally, the carbon dioxide content of the atmosphere is continuing to rise. This makes the scientists wonder where the rising CO2 is coming from. Is the…
