Earth’s wet regions are getting wetter and dry regions are getting drier due to global warming, according to a new study. Researchers from University of Southampton in the UK found that the regions, which are relatively wet, like Northern Europe are getting wetter and dry regions are getting drier. This process is called amplification of the water cycle.
Researchers used measurements of salinity throughout the global and deep oceans over the last 60 years to estimate how much global rainfall is changing. Previous research indicates that amplification of the water cycle is happening at seven per cent per one degree Celsius of global warming. The new study estimates that amplification happens at about three to four per cent per one degree Celsius.
