A warmer world is making high latitude forests more deciduous and less evergreen, research shows. Global heating has increased the likelihood of extreme events such as wildfires and storms and this warmer and less stable environment is favouring deciduous trees over evergreens.
Boreal forest stretches for miles and miles across high northern latitudes, covering huge swathes of Canada, Russia, Alaska and Scandinavia. It makes up nearly a third of global forest area and is mainly made up of evergreen trees such as spruce and fir. But this landscape could change.
