Major Conclusions in
SPM
1.An
increasing body of observations gives a collective picture of a warming
world and other changes in the climate system.
2.Emissions
of greenhouse gases and aerosols due to human activities
continue to alter the atmosphere in ways that are expected
to affect the climate.
3.Confidence in the
ability of models to project future climate has increased.
4.There is new and
stronger evidence that most of the warming observed over the
last 50 years is attributable to human activities.
5.Human
influences will continue to change atmospheric composition
throughout the 21st century.
6.Global
average temperature and sea level are projected to rise under
all IPCC SRES scenarios.
7.Anthropogenic
climate change will persist for many centuries.
8.Further
action is required to address remaining gaps in information
and understanding.
