I think this is whats referred to as global dimming.
That much more pollution in the atmosphere, that much less sunlight reaching earth= unstable new weather patterns and cooling. Its offsetting the warming.
For example if you remember that over the 3/4 days all aircraft were grounded over 9/11, temperatures were several degrees lower because the sky was not jammed full of aircraft trails. |

| I wish they had named "Global Warming" something more along the lines of "Global Weather Instability." Too many partisan, unscientific dousches misrepresent unpredictable weather as unrelated to the damage we are doing to the planet via various forms of pollution. |

That should be higher, not lower. Contrails reflect sunlight in the upper atmosphere increasing the earth's albedo.
And one year doesn't make a trend. The main thing to remember about anthropogenic climate change is that we're essentially pumping more energy into the system by trapping more heat closer to the earths surface with CO2 and other gases. This leads to various positive and negative feedbacks. |

Well, with suddenly clear skies, the daily temperature range was markedly wider- ie, higher temperatures by day and colder at nights.
Those few days of grounding were unique in recent history and really put a blip on the weather records.
I'm not sure if you watched a documentary (I think it was called "global dimming") showing how evaporation and sunlight have both decreased something like 25% over the past 30 years and the impacts this has had on various climates. |
