global warming

Have we solved the ozone depletion problem and if so why can’t we get a handle on global warming as well?

Caption: Data from NASA shows a decrease in the seasonal ozone hole above Antarctica over the last decade thanks to the phase-out of CFCs and other ozone-depleting chemicals as called for under 1987’s landmark Montreal Protocol.

NOAA 2017 temperatures

Assessing the Global Climate in 2017

For the globe, 2017 was the third warmest year on record and the warmest year without an El Niño present. The globally averaged temperature over land and ocean surfaces for 2017 was the third highest since record keeping began in 1880, according to NOAA scientists. December’s combined global land and ocean average surface temperature departure…

NASA Study: Proof of Ozone Hole Recovery

For the first time, scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion. Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing man-made chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 percent less ozone depletion…
