Loss of groundwater may accelerate drying trends in the eastern United States, according to research that applied supercomputing to create an in-depth model of how groundwater will respond to warming.
Nonperennial rivers are a major—and growing—part of the global river network. New research and science-based policies are needed to ensure the sustainability of these long-overlooked waterways.
University of Arizona researchers studied recent extinctions from climate change to estimate the loss of plant and animal species by 2070. Their results suggest that as many as one in three species could face extinction unless warming is reduced.
'Nobody saw it coming this soon,' one scientist said. 'It's likely the forests won't be coming back as we know them.'
