The Earth ... is actually headed into a mini Ice Age

... heavyweight US solar physicists announce that the Sun appears to be headed into a lengthy spell of low activity.

UPDATE: The indefatigable Steve McIntyre makes another point (for science):

Returning now to the original lead to the IPCC Press Release on renewables:

Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows.

The basis for this claim is a Greenpeace scenario. The Lead Author of the IPCC assessment of the Greenpeace scenario was the same Greenpeace employee who had prepared the Greenpeace scenarios, the introduction to which was written by IPCC chair Pachauri.

The public and policy-makers are starving for independent and authoritative analysis of precisely how much weight can be placed on renewables in the energy future. It expects more from IPCC WG3 than a karaoke version of Greenpeace scenario.
