Loofbomen in het noordpool gebied kan voor meer opwarming zorgen

Expansion of deciduous trees could make Arctic warm faster


A new simulation of deciduous tree expansion into the Arctic region shows that the trees would block the highly reflective snow and increase cloud cover, causing the area to warm even faster than it already is.


Although temperatures have risen throughout the globe, they've gone up most dramatically in the Arctic. Past warm periods indicate that deciduous tree expansion into the Arctic is a common occurrence when the region warms up, so a new study has looked into the impact trees could have on the regional climate. As expected, the increase of the leafy trees would result in less reflective ground, but the study suggests they could also induce more cloud cover and an increasingly warm surface and ocean that have more turbulent weather patterns.
