Ecosystems in North America’s Great Plains have shifted hundreds of miles northward in the past 50 years, driven by climate change, wildfire suppression, energy development, land use changes, and urbanization, according to a recent study published in the journal Nature Climate Change.

Bark beetles are currently responsible for killing an unprecedented number of trees in forests across Europe and North America. 

Global sea levels are expected to rise by at least half a metre by the year 2100 due to climate change.
