The UN's IPCC climate models found, by scientists, to be abject failures at global warming and/or climate change predictions
Read here. It is now believed by over 97% of all physical science scientists that the IPCC's climate models have failed to accurately predict recent changes in global temperatures and associated climate change. The inconvenient facts of climate model prediction failure have become well known and are no longer denied by the world's science community.
- (Note to readers: Try to find a single PhD in physical sciences whom actually believes, and will state in writing, that the climate computer simulations have been accurate over the last 15 years....good luck with that.)
The latest peer-reviewed research by Chinese scientists, Fu et al., substantiates what the vast majority of scientists have concluded: IPCC computer climate models are presently incapable of producing accurate climate predictions and will continue to be unable to do so for the foreseeable future.
"In setting the stage for their study, the authors note that the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) concluded that climate projections based on models that consider both human and natural factors provide "credible quantitative estimates of future climate change." However, as they continue, mismatches between IPCC AR4 model ensembles and observations, especially the multi-decadal variability (MDV), "have cast shadows on the confidence of the model-based decadal projections of future climate,"...evaluated "many individual runs of AR4 models in the simulation of past global mean temperature," focusing on the performance of individual runs of models included in the Coupled Model Intercomparison Project phase three (CMIP3) in simulating the multi-decadal variability of the past global mean temperature...they determined that "most of the individual model runs fail to reproduce the MDV of past climate, which may have led to the overestimation of the projection of global warming for the next 40 years or so.""
