“…Read carefully with other official data, they conceal a truth that for some, to paraphrase former US VicePresident Al Gore, is really inconvenient: for the past 15 years, global warming has stopped.”
“…Earlier this year, a paper by Michael Mann – for years a leading light in the IPCC, and the author of the infamous ‘hockey stick graph’ showing flat temperatures for 2,000 years until the recent dizzying increase – made an extraordinary admission: that, as his critics had always claimed, there had indeed been a ‘ medieval warm period’ around 1000 AD, when the world may well have been hotter than it is now.”
“..He wrote: ‘The fact is that we can’t account for the lack of warming at the moment, and it is a travesty that we can’t.’…”
“..Actually, with the exception of 1998 – a ‘blip’ year when temperatures spiked because of a strong ‘El Nino’ effect (the cyclical warming of the southern Pacific that affects weather around the world) – the data on the Met Office’s and CRU’s own websites show that global temperatures have been flat, not for ten, but for the past 15 years…”
“…After the leak, Trenberth claimed he still believed the world was warming because of CO2, and that the ‘travesty’ was not the ‘pause’ but science’s failure to explain it.”
“…The question now emerging for climate scientists and policymakers alike is very simple. Just how long does a pause have to be before the thesis that the world is getting hotter because of human activity starts to collapse?….”
