Key questions scientists will need to address are how global reforestation might affect Earths surface albedo (reflectivity) and evapotranspiration. In the near term and locally, says Saatchi, forest restoration may actually have a warming effect. As the trees mature, the new forest canopy cover would presumably make Earths surface albedo darker, particularly in the Northern Hemisphere during periods of snow cover, causing it to absorb more heat. Increasing forest cover, particularly in the tropics, will increase evapotranspiration, causing a cooling effect. With Earth already warming significantly due to greenhouse gas emissions, will forest reforestation on a global scale have a net warming or cooling effect on our planet, and will the benefits of reforested areas absorbing more carbon outweigh their increased heat absorption?

I really don't understand these our scientists. One day they are coming with the fact that deforestation is the reason why the air is not of good quality to breathe in and then they suggest that planting trees would solve the problem and the world began the planting of the trees even to the extent that we have a world planting tree day. Now, coming up with this means that they are saying we got it all wrong and we are even causing more damage with tree planting. It seems there is no way to please the ozone layer.

That's because 'scientists' aren't 1 person.

Is creating dopey threads in forum actually good for the planet?

Depends how the electricity is made.
If it's nuclear, then it isn't harmful.
If it's coal, then it increases CO2 which some would deem harmful.

Tree planting is always been beneficial to our earth. Here's why, as we all know trees can be useful in various ways. It produces the air we need by a method called photosynthesis that absorb heat then converts it to oxygen. Also trees is used to make papers, one example books that is used for entertainment, knowledge and also trees are home for various kinds of animals. So i dont see why not we should not plant trees.

It doesn't absorb heat, it absorbs CO2.
CO2 is apparently a good heat conductor.
