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.
