«Since the AR4, there is some new limited direct evidence for an
anthropogenic influence on extreme precipitation, including a formal detection and attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of
anthropogenic influence on various aspects of the
global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with
warming, at a rate well
exceeding that of the mean precipitation..
Modeled regional and
global climate responses to simulated (107, 110, 111) and reconstructed historical land cover changes over the past century (112) and millennium (113) generally agree that
anthropogenic deforestation drives biogeophysical cooling at higher latitudes and
warming in low latitudes and suggest that biogeochemical impacts tend to
exceed biogeophysical effects (113).
The current approach that is generally pursued assumes essentially that past climate variability is indistinguishable from a stochastic red - noise process... Given such a null hypothesis, the official consensus of IPCC (1995) tilts towards a
global warming effect of recent trace - gas emissions, which
exceeds the cooling effect of
anthropogenic aerosol emissions.»
