NASA Study Forecasts Global Warming to Trigger Global Rainfall and Drought

NASA recently revealed evidences that the risk of severe rainfall and drought worldwide may happen due to global warming.

The research team demonstrated through a modeling approach the effect of increasing amount of carbon dioxide concentrations on the rainfall types of Earth.

The team showed 14 computer simulations representing the 14 rainfall types worldwide such as those in the equatorial Pacific Ocean and Asian monsoon regions. The simulation showed that all regions will experience heavier rainfalls due to warming caused by an increasing level of carbon dioxide concentrations in the atmosphere changing the entire rainfall system.

William Lau of NASA's Goddard Space Flight Center in Greenbelt, Maryland, lead author of the study, expounded the different scenarios that may possibly happen. Each region may suffer from heavier rain, less moderate rain, or extended drought.

The study forecasts that for every 1 degree Fahrenheit increase on warming, there will be a 3.9 percent increase on heavy rainfall and 1 percent on light rains. Moderate rainfall drops to 1.4 percent.
Tropical zones near the Pacific Ocean and Asian monsoon regions will experience heavier rainfall while those outside may suffer from drought.
