Climate Change Causes Forest Die-Off Globally
Already facing an onslaught of threats from logging and conversion for agriculture, forests worldwide are increasingly impacted by the effects of climate change, including drought, heightened fire risk, and disease, putting the ecological services they afford in jeopardy, warns a new paper published in the journal Nature Climate Change.
The study, authored by William Anderegg of Carnegie Institution for Science at Stanford University and Jeffrey Kane and Leander Anderegg of Northern Arizona University, reviews dozens of scientific papers dealing with the ecological impacts of climate change. They find widespread cases of forest die-off from drought and elevated temperatures, which can increase the incidence of fire and pest infestations like pine beetles. These effects have the potential to trigger transitions to other ecosystems, including scrubland and savanna. But the impacts vary from forest to forest and the authors say more research is needed to fully understand the effects of climate change on forest ecosystems.
