Report request: I am a high school student who has requested that trees be planted on school property to combat climate change. I need to report to the school administration that such an effort will have a positive effect on climate before the administration agrees to set aside land for this effort.
I need a report that will convince the school administration of the efficacy of planting trees. I believe I can do this by reporting on experiments or trials that have planted trees specifically to affect the climate. Any claims that trees can or cannot slow or reverse climate change that are backed by evidence should be included.
