A new study looking at the impact of climate change on islands has shown that 73 percent will become "substantially more arid" by the middle of the century, up from a previous estimate of 50 percent.
According to a news release on Monday from the University of Colorado Boulder, global climate models, or GCMs, used by scientists to assess the impacts of climate change, do not take into account thousands of small islands across the planet. The study was published in the journal Nature Climate Change.
The new model found that because of increased evaporation, 73 percent of islands – rather than 50 percent – would become drier.
"Islands are already dealing with sea level rise," Kris Karnauskas, lead author of the paper and a fellow at the Cooperative Institute for Research in Environmental Science, said.
