Climate change: ‘staggering’ rate of global tree loss due to fires
About 16 tree-lined football pitches per minute were lost to wildfires in 2021, according to a new report.
Data from Global Forest Watch suggests that the amount of forest cover burned around the world has nearly doubled in the past 20 years. Climate change is a key driver of the increase as it leads to higher temperatures and drier conditions
the second worst year for fires on record, an area the size of Portugal was lost.
“It’s roughly twice what it was just 20 years ago. It is kind of astonishing just how much fire activity has increased over such a short amount of time.”
The impacts of fire losses are mainly felt in the forests of the northernmost countries such as Canada and Russia.
While the fire is a natural part of how these forests have long functioned, the scale of destruction seen in Russia in 2021 was unprecedented.
What’s most concerning is that fires are becoming more frequent, and more severe, and have the potential to unlock a lot of the carbon that’s stored in soils there.
Trees and soil store carbon dioxide, one of the main gases that warm our atmosphere, and experts say they are essential for fighting climate change. So, cutting down these forests actually makes them hotter and drier and makes them more prone to fires.
Although many trees that burn grow back over a period of 100 years or so, there are significantly associated impacts of these losses on biodiversity, water quality, and soil erosion.
