Foresting grassy areas, especially in regions that receive significant snowfall, can "have an additional warming effect" that when this warmer air travels over oceans, it increases ocean temperatures, causing evaporation, turning liquid water into water vapor & leading to additional temperature increases—further amplifying this feedback loop you have even more water vapor in the atmosphere, and that causes a stronger greenhouse gas effect oceans amplifying warming temp https://phys.org/news/2026-11-lesser-climate-impacts-global-reforestation.html
