GLOBAL WARMING MAPS: Early Warning Signs
The map of early warning signs clearly illustrates the global nature
of climate changes. In its 2001 assessment, the Intergovernmental
Panel on Climate Change (IPCC) concluded that, "an increasing body of
observations gives a collective picture of a warming world and other
changes in the climate system."
While North America and Europe—where the science is strongest—exhibit
the highest density of indicators, scientists have made a great effort
in recent years to document the early impacts of global warming on
other continents. Our map update reflects this emerging knowledge from
all parts of the world.
Although factors other than climate may have intensified the severity
of some of the events on the map, scientists predict such problems
will increase if emissions of heat-trapping gases are not brought
