William Anderegg, Assistant Professor in the School of Biological Sciences, has a central research question: What is the future of ecosystems in a changing climate?
His lab studies how drought and climate change affect forest ecosystems, and seeks to gain a better mechanistic understanding of how climate change will affect forests around the world. In a new study, Anderegg and colleagues look at the risks of banking on forests to store atmospheric carbon when forests themselves face a number of risks.

From the Science paper:
“Forests have considerable potential to help mitigate human-caused climate change and provide society with a broad range of cobenefits…Widespread climate-induced forest die-off has been observed in forests globally and creates a dangerous carbon cycle feedback, both by releasing large amounts of carbon stored in forest ecosystems to the atmosphere and by reducing the size of the future forest carbon sink. Climate-driven risks may fundamentally compromise forest carbon stocks and sinks in the 21st century. Understanding and quantifying climate-driven risks to forest stability are crucial components needed to forecast the integrity of forest carbon sinks and the extent to which they can contribute toward the Paris Agreement goal to limit warming well below 2°C. Thus, rigorous scientific assessment of the risks and limitations to widespread deployment of forests as natural climate solutions is urgently needed.”
