Cleaning up the air we breathe might actually be making droughts worse

Air pollution could be masking the role of greenhouse gases on droughts, a new study suggests.

Climate change is clearly making some regions wetter and others drier. But it’s been difficult for scientists to detect a clear, consistent human role in increasing the frequency and severity of global droughts given natural climate variability, regional differences, and limited data.

A new report in Nature adds evidence to the suspicion that air pollution could be complicating the science, masking the role of greenhouse gases on droughts.
