Trees and the Global Weather Systems with David Ellison

Trees don’t just produce oxygen as the air that we breath, they also produce all sorts of minute particles that contribute towards rain formation in varied and vital ways.  Forests draw moisture from the oceans and hydrate whole continents.  Or they can when there is enough of them.

It is now critical that we better understand the relationship between trees and the global weather systems which is why we have asked David Ellison, a researcher with the Swedish University of Agricultural Sciences (SLU, Umea) in the institute of Geography.

David’s work focuses broadly on the science, politics and policy of climate, primarily on forests, water and their relevance for climate and environmental policy.  He will be giving us a deeper insight into the role of the relationship between forests and water.  David is coordinating hydrologists and foresters to help groups working with the International Panel on Climate Change to make protecting our weather systems their number one priority.

The trees in the tropics have always played a major role in feeding water into the clouds that then get blown around the planet.  The atmospheric movement of weather systems then get pushed up towards the artic where they cool and arc back down to the topical belt in enormous snake like waves.  With the rising temperatures in the arctic and greater instability of the weather cycles it time to understand more about what the trees have been doing.
