Answer 1

Although it is difficult to connect specific weather events to global warming,an increase in global temperatures may in turn cause broader changes,including glacial retreat,Arctic shrinkage,and worldwide sea level rise.Changes in the amount and pattern of precipitation may result in flooding and drought.There may also be changes in the frequency and intensity of extreme weather events.Other effects may include changes in agricultural yields,addition of new trade routes,reduced summer streamflows,species extinctions,and increases in the range of disease vectors.
Some effects on both the natural environment and human life are,at least in part,already being attributed to global warming.A 2001 report by the IPCC suggests that glacier retreat,ice shelf disruption such as that of the Larsen Ice Shelf,sea level rise,changes in rainfall patterns,and increased intensity and frequency of extreme weather events,are being attributed in part to global warming.While changes are expected for overall patterns,intensity,and frequencies,it is difficult to attribute specific events to global warming.Other expected effects include water scarcity in some regions and increased precipitation in others,changes in mountain snowpack,and adverse health effects from warmer temperatures.
