...The IPCC process remains a human endeavour and, as such, is subject to human error; the silly mistake in the previous report that Himalayan glaciers would melt completely by 2035 demonstrates this. But the rarity of such errors shows what a solid job the organization has done. Critics went through the rest of the more-than-900-page report with a fine-tooth comb but found little else of significance to crow about.
...Absent from next week’s report, for instance, is recent and ongoing research on the rate of warming and what is — or is not — behind the plateau in average global temperatures that the world has experienced during the past 15 years. These questions have important policy implications, and the IPCC is the right body to answer them. But it need not wait six years to do so.

Philosophy was Edenhofer's intellectual refuge early on. Hailing from an arch-conservative part of Bavaria in south Germany, he shocked his parents — and prompted the local book seller to declare him crazy — when he spent his savings at the age of 14 on the three volumes of Das Kapital by Karl Marx. Reading the German philosopher's critique of the capitalist mode of production didn't turn him into an ardent Marxist, but did spark his interest in political economicsClimate change: A patchwork of emissions cuts : Nature News & Comment
