Climate Change IPCC 2013: The psysical science basis - GreenFacts summary

GreenFacts has produced a summary of the “Physical science basis” of climate change, which is the first part of the new report of the Intergovernmental Panel on Climate Change (IPCC).

This report is a comprehensive assessment of the physical aspects of climate change and focuses on the elements necessary for understanding past change, documenting current, and projecting future climate change. These summaries are intended to help people better understand parts 2 and 3 of the IPCC Report that are coming soon and which deal with climate impacts and the mitigation potential.

Read the full summary in English here. The level 1 summary is already available also in French and Spanish.
