Global Dimming

A short documentary from BBC about the phenomenon

GLOBAL DIMMING:
Manifestations:
a. decrease in solar energy (israel and germany's bavarian alps)
b. fall in pan evaporation rate

Experiment:
Project Indo X: polluted north and pristine south Maldives
pollutants have more surface where the water molecule can fall but is far more smaller than it is normally.

thus, more small water molecule would reflect more light... reflect sunlight, thus not allow sunlight to pass through and appearing the clouds to be bright

Ethiopian Drought maybe caused by the fall of sunlight as the sunlight is necessary to drag the rainfall to the area (african monsoon) thus resulting to failure in rainfall

But without global dimming, also a threat!
catch: as we are in threat to the phenomena of global dimming, it is (to some extent) protecting us from greater threat!!!
Experiment :9/11 aftermath and contrails
Dr Travis
contrails! no contrails when comml planes were grounded
thus establish the effect of contrails to the atmosphere
sept 11-13 = highest temperature range, jumped to 1 deg cel
(warmer in day/cooler in night) - lack of clouds
-drop in global dimming because airplanes were grounded (there were no contrails). The findings implied that decrease in global dimming resulted in higher temperature ( higher temperature range)


GLOBAL WARMING VS. GLOBAL DIMMING
-from greenhouse gases warming and from particle pollutants
-we are more inclined towards global warming
-the bottomline is we can't confront global dimming without confronting the real culprit-pollution from various industries that contribute to greenhouse gases; in our attempt to cover up global dimming, we are positioning ourselves to a bigger threat of global warming.
