Read here. The admission by a new paper published in the PNAS journal that there has been no global warming since 1998 is stunning in its implications. First, it unabashedly means that UN and national government climate scientists and bureaucrats have simply been lying about the "accelerating," "unequivocal," and "unprecedented" warming that supposedly took place over the last decade plus.
Second, it means the multi-billion dollar climate models that have long predicted global warming (due to the continuous growth of human CO2 emissions) are essentially worthless. Since 1998, the models have been an admitted disastrous failure - they don't work as promised or as advertised by the IPCC.
To further emphasize this latter point, a new peer reviewed study by Fu et al. determines that the climate models have consistently exaggerated the predicted warming of the tropical upper atmosphere. The failure of this prediction is a body blow to the "consensus" science.
If the atmosphere does not actually warm as predicted, the feared IPCC global warming tipping point can't happen.
Realistically and objectively, the evidence grows that the climate model predictions are based on the robustly dysfunctional, teetering CO2-based AGW hypothesis.
"“IPCC AR4 (Fourth Assessment Report) GCMs (General Circulation Models) predict a tropical tropospheric warming that increases with height...“One of the striking features in GCM-predicted climate change due to the increase of greenhouse gases is the much enhanced warming in the tropical upper troposphere. Here we examine this feature by using satellite MSU/AMSU...“IPCC AR4 GCMs overestimate the warming in the tropics for 1979-2010...While strong observational evidence indicates that tropical deep-layer troposphere warms faster than surface, this study suggests that the AR4 GCMs may exaggerate the increase in static stability between tropical middle and upper troposphere in the last three decades. In view of the importance of the enhanced tropical upper tropospheric warming to the climate sensitivity and to the change of atmospheric circulations, it is critically important to understand the causes responsible for the discrepancy between the models and observations.”" [Q.
