A study analyzing tropical tree ring data found that trees experienced diminished growth in years of drought.
The trees can rebound in wetter years, but that comes with a catch.
The study compiled tree ring data from about 20,000 records worldwide and had about 150 collaborating contributors and authors, including researchers with the University of Arizona.
They wanted to see how dry seasons can impact the ability of trees to capture carbon dioxide.
They evaluated the impacts of drought on tropical trees and found that while growth was 2.5% lower in dry years, some could recover years following drought.
The scientists warn though that climate change could diminish those tree’s resilience and ability to recover.
The study was published in the journal Science.
