However, the report found that the IPCC perspective was the mean opinion of climate scientists, and there was a fairly equal minority on each side. 18% thought the IPCC was overestimating, 17% thought the IPCC was underestimating, and the rest thought it was about right.

Invertebrates: Potato aphids grown on plants kept in elevated CO 2 (700 ppm) showed a reduced response to alarm pheromones in comparison to those grown on plants in ambient CO 2 (350 ppm). Aphids were more likely to remain on leaves, possibly making them more susceptible to predators (Awmack et al., 1997b).
You accuse the IPCC of losing credibility for promoting a target limit of 350 ppm… but that target does not appear in the IPCC reports. I also note that you give absolutely NO reason for believing that Hansen’s 350 ppm limit is ‘wrong’.
