IPCC Climate Change 2013, first report

The IPCC 2013 report on The Physical Basis for Climate Change by Working Group 1 is available, both as a complete report and as a Summary for Policymakers at the IPCC web site. I chose to review the summary, which contains key elements highlighted in tan blocks.

You may also want to review the basis for the 4 scenarios they use, known as RCPs for Representative Concentration Pathways. In a nutshell they range from RCP 2.6 which is very aggressive emissions reduction, to RCP 8.5 which is kind of "life as usual" (my definition).

Another thing to be aware of, all the figures referred to in the Summary for Policymakers can be found at the END of the report.

My perspective on the report? It adds a great deal of scientific evidence supporting the human causes of climate change observed so far, and it paints a bleak picture for the future.
