in precipitation..

A sentence
in Chapter 13 of the 2007 IPCC Fourth Assessment Report on Impacts, Adaptation and Vulnerability states: «Up to 40 percent of the Amazonian forests could react drastically to even a slight reduction
in precipitation; this means that the tropical vegetation, hydrology and climate system
in South America could
change very rapidly to another steady state, not necessarily producing gradual
changes between the current and the
future situation.»

Obviously, climate models whose hindcasts differ
in sign from what is observed (Zhang et al., 2007), or which indicate that human influences are indistinguishable from natural
changes (Sarojini et al., 2012) possess no skill

precipitation across the U.S. and therefore should not be used to make
future projections.

precipitation has
changed already — further reducing confidence
