Direct Observationsof Recent Climate
Change
There is observational evidenceof increase intensity oftropical cyclone activity inthe North Atlantic since 1970
correlated with the increasein sea surface temperature.
Cold days, cold nightsand frost have
become less frequent.While hot days, hotnights, and heatwaves have becomemore frequent.
More intense and longer droughtssince 1970 particularly in thetropics and subtropics due toincrease in temperature anddecrease in precipitation.

Regional Effects of CC in Asia
AgricultureMany crops grown in Asia are very sensitive to soil
moisture and temperature, and global warming may upset
a delicate balance and reduce crop yields here.
