Seriously. Quit with the tree planting. Stop it.
“Climate scientists have calculated the effect of increasing forest cover on surface temperature. Their conclusion is that planting trees in the tropics would lead to cooling, but in colder regions, it would cause warming.”

One reaches a point where sarcasm, humor, ridicule, and facts, all fail in trying to say something intelligent about the “Global Warmist’s statements”.
Nadine Unger is an assistant professor of atmospheric chemistry at Yale. This University carries some historical esteem, but is still no a guarantee of accurate science nor balanced reasoning. Everyone enjoys the shade of a tree in a park during sweltering heat. Trees can be used for building houses. Even if a tree is allowed to decay into mulch the release of CO2 is delayed, sometimes centuries. This uptake and delayed release could be exactly what the doctor ordered. Trees reduce need to run air conditioning too cool off buildings. So many values left unlisted, that calling trees a zero net is just plain ridiculous..
Maybe the reverse of burning fossil fuels should be done? Plant new trees. In northern parts of the world systematically cut down the trees of the forest at their prime and under no circumstances allow the tree to simply rot down. Best CO2 sequestering and energy conservation would be to use wood for construction instead of metal or concrete. Production of metal and concrete often uses fossil fuels. Trees and forestry reduces global warming. It is obvious that Nadine and her Alma Mater is not a direct beneficiary of forestry. It makes sense. Canada has way more trees than USA. The USA excels in other areas, unfortunately of the polluting and wasting nature.
Trees have plenty of benefits other than “reducing global warming.”
And, as quoted by sunshinehours on ‘The Denier Credo’ : “More CO2 is good for agriculture. Warmer is good for people.” Ahem, *consistency*.
