Previous warnings have been born out: rising temperatures, melting glaciers, loss of biodiversity, greater storm intensity, acidification of the oceans, increases in deadly heat waves. The main failing of the models is that they consistently underestimated how quickly glacial melt, acidification, and acceleration of heatstroke death would come about.
No mainstream climate scientists have been "caught with their pants down in deceptions, inaccurate climate models [no, the models are not perfect, but they are refined in the light of new data and a much better predictor of future outcomes than the "no warming" model or even the models of leading contrarians who acknowledge AGW but deny that it is the main source of recent climate variability] and manipulation, or removal of data." This is simply a lie repeated over and over by people for whom the scientific facts are politically (i.e., economically) inconvenient. There is no evidence for it. None.
