Tweaking the climate models: Researchers show emissions from forests influence very first stage of cloud formation

Watts Up With That?

Clouds_over_Amazon These clouds are almost certainly a result of evapotranspiration. The clouds are distributed evenly across the forest, but no clouds formed over the Amazon River and its floodplain, where there is no tall canopy of trees. While water may evaporate from the Amazon River itself, the air near the ground is too warm for clouds to form. Trees, on the other hand, release water vapor at higher levels of the atmosphere, so the water vapor more quickly reaches an altitude where the air is cool enough for clouds to form. When water vapor condenses, it releases heat into the atmosphere. (NASA image courtesy Jeff Schmaltz, MODIS Rapid Response at NASA GSFC )

In the midst of all the Climate McCarthyism on display, I almost missed this important finding. Of course, most daily forecast meteorologists that watch satellite and radar have known this for decades, but it is nice to see…

  1. not sulfur dioxide” but ”carbon dioxide” increases water vapor condensation – because CO2 is good for absorbing / releasing heat, (same as metal) – in the upper atmosphere CO2 is very cold and, coldness increases condensation
