IPCC 4th Assessment
Report
Comparing
the IPCC AR4 to the TAR
Brussels,
1 February 2007. GreenFacts will publish clear,
faithful summaries of the IPCC 4th Assessment Report (AR4)
on www.greenfacts.org
in the course of 2007. GreenFacts was invited to be present at the Sessions
of the three IPCC Working Groups, and intends to rapidly summarise each
Working Group’s SPM (Summary for Policymakers) after its release.
“There
are a lot of signs and evidence in this report which clearly establish
not only the fact that climate change is taking place, but also that it
really is human activity that is influencing that change,”
said IPCC chairman Rajendra K. Pachauri at a news briefing in Paris this
week. “[The report] embodies substantial new research, it addresses
gaps that existed in our knowledge earlier, it has reduced existing uncertainties.”
The
findings of the AR4 build on those of the IPCC Third Assessment Report
(TAR) published in 2001. A clear and faithful summary of the TAR is available
at
www.greenfacts.org/studies/climate_change/
in English, German, Spanish, and French. It is a useful tool for comparing
the two assessments.
The
Intergovernmental Panel on Climate Change was established in 1988 by WMO
and UNEP with a mission to assess whether climate change is caused by
human action and to look at options to mitigate it. The three working
groups of the IPCC that will publish their reports in February, April,
and May this year will look at the science and the impacts of climate
change, as well as mankind’s option to mitigate climate change.
For
information on other climate-change related topics such as Arctic Climate
Change, Desertification, Ecosystem Change, please consult the GreenFacts
website on www.greenfacts.org. All the information GreenFacts provides
on its website is based on international authoritative scientific consensus
documents.
