So many years of no warming means it’s time to rethink

Andrew Bolt,Herald Sun (Australia)
" Some argue that the duration of the standstill is too short to be meaningful. Thirty years is taken to be the baseline for observing climate changes and fifteen years is too short. This report argues that 15 years is not an insignificant period; what has happened to make temperatures remain constant requires an explanation. The period contains important information and should not be dismissed as having no climatic importance. The recent warming period began about 1980 after four decades of globally stable temperatures thus the years of constant temperature are about equal to years when temperatures increased. This is not a trivial observation.
Calculations based on ensembles of climate models suggest prolonged standstills of about ten years can occur once every eight decades. Standstills of 15 years are much more difficult to explain. This report shows, that if we have not passed it already, we are on the threshold of global observations becoming incompatible with the consensus theory of climate change."
