In the required reading category for all humans, the 5th IPCC (Intergovenmental Panel on Climate Change) report, Climate Change 2013 – The Physical Science Basis, now uses the unambiguous term “unequivocal” when describing global warming. I don’t think there is a more robust “canary in the coal mine” warning for us to take action upon (forgive the tortured pun).

“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased.”
Opportunities to reinvent our economic system to support the next phase of our existence in a sustainable fashion are exciting to anyone who loves innovation, value creation, economic growth, and well being. However, policy needs to level the playing field so we get there faster with less unnecessary friction.
The Summary is available now on the IPCC site –IPCC   The full report will be available on September 30, 2013.  All legislators should read this document to be informed when debating policy.
