Interpreting
past and present climate data is difficult, but predicting future
climate change—and its possible effects—is even more
challenging. Researchers use complex computer simulations
called climate models to predict long-term weather patterns.
A model’s reliability depends on the number of variables
taken into account and the accuracy of measurements used.
What are the possible implications of continued global climate
change?
Researchers are studying a variety of areas, from variations
in the frequency and intensity of storms to changes in the incidence
of mosquito-borne diseases. Rising sea levels can flood coastal
areas, and habitat changes can cause the extinction of some
species of plants and animals. Increases in precipitation can
cause floods and landslides, while decreases may lead to droughts
and wildfires. This range of possible effects is one reason
why many types of scientists are keenly interested in understanding
the earth’s changing climate.
