Indur Goklany notes a rather egregious example of IPCC perjury.
The third statement in the panel devoted to water impacts states, “Hundreds of millions of people exposed to increased water stress.” If one traces from whence this statement came, one is led to Arnell (2004). [Figure SPM.2 misidentifies one of the sources as Table 3.3 of the IPCC WG 2 report. It ought to be Table 3.2. ]
What is evident is that while this third statement is correct, Figure SPM.2 neglects to inform us that water stress could be reduced for many hundreds of millions more – see Table 10 from the original reference, Arnell (2004). As a result, the net global population at risk of water stress might actually be reduced. And, that is precisely what Table 9 from Arnell (2004) shows. In fact, by the 2080s the net global population at risk declines by up to 2.1 billion people (depending on which scenario one wants to emphasize)!
And that is how a net positive impact of climate change is portrayed in Figure SPM.2 as a large negative impact. The recipe: provide numbers for the negative impact, but stay silent on the positive impact. That way no untruths are uttered, and only someone who has studied the original studies in depth will know what the true story is. It also reminds us as to why prior to testifying in court one swears to “tell the truth, the whole truth and nothing but the truth.”
Figure SPM.2 fails to tell us the whole truth.
Anyone commenting on EPA’s suggestion in its ANPR (pp. 387-388 and 411-412) that it ought to rely solely on the risible U.S. Unified Synthesis Product and these intentionally misleading IPCC reports as the scientific basis for promulgating greenhouse gas regulations should ensure their comments include a resounding “NO!”
