Introduction
The observed absence of a global-warming trend (often described as “pause” or “hiatus”), beginning around Yr 2000 (or perhaps even earlier) contradicts the results of every IPCC climate model – all of them driven by a steady increase in anthropogenic carbon dioxide; see figure. This lack of model validation has obvious implications for model-based estimates of future climate. Until the cause of the pause is better understood and incorporated into existing models, all policies aiming to stabilize climate are useless and are nothing more than highly uncertain and hugely expensive exercises.
The label of “pause” (used by UN-IPCC alarmists) suggests that absence of a warming trend is only temporary — and that warming may soon resume. This seems to be the opinion of well-known climate alarmists; climate skeptics, by and large, have not published their views about the end of the pause.
