Trees have their benefits, until they start impeding on maintenance, quality of life, or safety. That's why there are parks and agricultural reserves - to have trees for environmental benefits, but away from personal property.
The first issue is that trees are dark, at least compared to other things that might blanket the land, such as grass or snow. As a result, planting more trees typically makes the land darker. Since dark surfaces absorb more heat, a dark tree-covered surface will trap more of the Sun’s heat – and warm the local climate.
As a result, there is a delicate balance between trees’ ability to take in CO2, reducing warming, and their tendency to trap additional heat and thus create warming. This means planting trees only helps stop climate change in certain places.
Specifically, according to a 2007 study that has been repeatedly confirmed, the best place to plant new trees is the tropics, where trees grow fastest and thus trap the most CO2. In contrast, planting trees in snowy regions near the poles is likely to cause a net warming, while planting them in temperate climates – like that of the UK, much of Europe and parts of the US – may have no net effect on climate.
