Read here and here. The mind-numbing, repetitive refrain of "the climate models predict" by AGW alarmists has become a joke in the science world, and is often used by comedians as a setup for the punch line of their weather jokes. As has been thoroughly documented, the predictions of climate models and experts are rarely of more value than used toilet paper. The latest IPCC global warming prediction discovered to be erroneous? The direction of mountain vegetation growth.
A new peer-reviewed study by Crimmins et al. discovered that actual California mountain vegetation has been moving downslope instead of upslope on the mountain terrain in spite of global warming. The downslope movement of plants is the exact opposite as predicted by IPCC Climategate scientists and their computer models. This is more climate-change empirical evidence that is not consistent with any IPCC computer model.
“Predictions that climate change will drive trees and plants uphill, potentially slashing their range to perilous levels, may be wrong, suggests a new study that found vegetation in California actually crept downhill during the 20th century.”.....“But comparing data from the early and late 20th century, authors of the Science paper found that despite warming, many plant species in California mountain ranges are growing at lower elevations than they did 80 years ago."....."research in the Eastern Sierra and the Great Basin has also found that tree lines are moving down rather than up, although for slightly different reasons."
