Read here. The pro-IPCC climate scientists predicted that mudslides and landslides (debris-flow) would increase due to global warming. Researchers examined the historical evidence and found the prediction to be without empirical merit. It appears that the left/liberal/progressive global warming, alarmist scientists (and IPCC) are again caught hyping calamitous predictions without the requisite scientific evidence.
"Matthews et al. report they could find "no obvious correlation between debris-flow frequency and a relative warm climate." In fact, they say that "debris-flow frequency was lowest post-8000 cal. BP during the Holocene Thermal Maximum," and that most of the "century- to millennial-scale phases of enhanced debris-flow activity appear to correlate with Neoglacial events," one of which was the "Little Ice Age."....they report that "there appears to be no consistent upward trend in debris-flow frequencies over recent decades," when one might have expected them to be growing in both number and magnitude if climate-alarmist claims were correct."
