How Trees Can Influence the Global Climate

26.02.2019

Researchers from University College London assume a connection between the end of the medieval warm period and reforestation.

When Europeans came to America in 1492, they brought unknown diseases for which the indigenous people had no immunity. A bit more than a century after Columbus’ arrival around 90% of the population had been lost.

The 56 Million deaths had an unexpected effect:

An area of almost 60 million hectares was no longer needed because of fall in population. Therefore, former farmland and pasture reverted back to forest. By 1610 it meant that atmospheric carbon dioxide (CO2) dropped leading to the dawn of the “Little Ice Age”, ending the medieval warm period. This new period was marked by much colder winters and summers in Europe.

That means: Reforestation can really help us to slow down the climate crisis now.
