Future Drought Risks May Be Overstated

Problems with computer modeling again

Some computer models for global warming may be over-estimating the risk of drought, according to a study published on Wednesday by the journal Nature.

Several key models used in climate research that factor in warming trends suggest that droughts will intensify as world temperatures rise.

This is on the basis that dry soils have less moisture to suck up into the atmosphere, which reduces rainfall and thus causes even greater aridity.
