Forests around world being changed from carbon sinks into carbon sources, making it harder to slow global heating

Wildfires are burning through the carbon budget that humans have allocated themselves to limit global heating, a study shows.

The authors said this accelerating trend was approaching – and may have already breached – a “critical temperature threshold” after which fires cause significant shifts in tree cover and carbon storage.

“Alarmingly, the latest temperature at which, globally, these impacts become pronounced is 1.34C – close to current levels of warming [above preindustrial levels],” said the UK Met Office, which led the research…

… Climatologists say the already dire situation will deteriorate until humankind, particularly in the wealthy global north, stops burning fossil fuels.
