Thinned out forests lose their cooling capacity. Using global satellite data, they found “that for 67% of sampled areas across the world, afforestation would increase low level cloud cover, which should have a cooling effect on the planet.”
While an increased water vapor in the atmosphere due to forests may result in greater radiation absorption (16), the impact is minor compared to the radiative effect caused the change in albedo, so that evaporative cooling is essentially a nonradiative effect.”įorests mean more cooling cloud formationĪ similar result was reached in another paper published last year in Nature Communications: “ Revealing the widespread potential of forests to increase low level cloud cover” authored by Duveiller et al. wood pellet production - will serve to lessen the cooling effect, or even cause warming. To the contrary, efforts that lead to the thinning or even the destruction of forests - e.g.
Thus efforts to keep forests intact at midlatitudes would help cool the earth’s surface. Clouds tend to form more over intact forests than they do over forest-free areas.įorests along with the clouds they help create, act to cool surface temperatures. These high albedo clouds play a major role in terms of having a cooling effect.
This means that scientists earlier had not adequately taken the clouds that formed due to forests into account. Using both satellite data and atmospheric boundary-layer models, they show that by including cloud–albedo effects due to land–atmosphere interactions, the R&A cooling at midlatitudes becomes prevalent. In their study, “ Cloud cooling effects of afforestation and reforestation at midlatitudes” the team of authors led by Sara Cerasoli carefully analyzed R&A at midlatitudes. But now recent studies suggest that burning wood pellets coming from harvested trees in forest thinning operations may instead be accelerating warming.Ĭloud–albedo effects due to land–atmosphere interactions Wood pellets are viewed as renewable and thus are supposed to be brakes on climate change. But others doubt forests play much of a role.Īnother solution proposed for climate protection is to burn wood pellets instead of oil and natural gas for heating buildings. Reforestation and afforestation (R&A) are among the most prominent ideas for the sequestration of CO2 and thus viewed by alarmists as a climate solution. March 2022 4 recent studies tell us that forest thinning for the production of wood pellets and clear cutting for wind parks are really dumb ideas.
