Image from NASA updated: As many noted, I (idiotically) cited the Montreal Protocol's success here, which has nothing to do with reducing tropospheric ozone -- rather, it has to do with fixing the ozone layer. Thank you commenters, and my apologies for

Good news: The ban on CFC-based asthma inhalers is rapidly approaching. Inhalers are going green and by December 31, all inhalers must be powered by hydrofluoroalkane (HFA) instead of the ozone-harming chlorofluorocarbons (CFCs).

Forty percent: That is the share of annual oceanic carbon dioxide uptake accounted for by the Southern Ocean. Given that oceans comprise Earth's largest carbon sink, that is not an insignificant figure;

In late September, NASA's Upper Atmospheric Research Satellite will crash into Earth. Weighing more than 1,300 pounds and roughly the size of a school bus, the satellite will likely land somewhere between Canada and South

Hopefully someday we can say the same thing about an effective effort to combat greenhouse gas emissions.

New NASA study offers first direct proof that the ozone hole is recovering thanks to the Montreal Protocol treaty and the international ban on CFCs.

The first field test of injecting sulfate particles into the atmosphere is proposed for New Mexico; ocean iron fertilization experiment shows more promise than previous ones.

It may have also been done under falsely obtained consent...

Because the iron dumped in the ocean off British Columbia wasn't dumped as waste, it didn't violate international law.
