Abstract:
The Working Group I contribution to the IPCC Fourth Assessment Report describes progress in
understanding of the human and natural drivers of climate change1, observed climate change, climate
processes and attribution, and estimates of projected future climate change. It builds upon past IPCC
assessments and incorporates new findings from the past six years of research. Scientific progress since the
TAR is based upon large amounts of new and more comprehensive data, more sophisticated analyses of
data, improvements in understanding of processes and their simulation in models, and more extensive
exploration of uncertainty ranges.
The basis for substantive paragraphs in this Summary for Policymakers can be found in the chapter
sections specified in curly brackets.
