Scientists studied the effect that changes in greenhouse gases and sulphate aerosol concentrations in the atmosphere had on precipitation over the past century. Human-induced climate change has also contributed to drying of a region north of the equator which incorporates Mexico, Central America and northern Africa.
The Environment News Service reported that the study also suggests that natural factors have contributed to the changes observed, but to a lesser extent than human activity.
