Global warming “pause” may last for 20 more years

Even though the “consensus” described in the IPCC report says it won’t. Gee, who to believe – the IPCC who has been badly off the mark since it began reporting or other scientists who actually research the climate, like Prof. Judith Curry from Georgia Tech?
The 17-year pause in global warming is likely to last into the 2030s and the Arctic sea ice has already started to recover, according to new research.
A paper in the peer-reviewed journal Climate Dynamics – by Professor Judith Curry of the Georgia Institute of Technology and Dr Marcia Wyatt – amounts to a stunning challenge to climate science orthodoxy.
Not only does it explain the unexpected pause, it suggests that the scientific majority – whose views are represented by the UN Intergovernmental Panel on Climate Change (IPCC) – have underestimated the role of natural cycles and exaggerated that of greenhouse gases.
Yeah, I’ll go with Prof. Curry if you don’t mind.
My favorite line from the article is one of vast understatement:
The research comes amid mounting evidence that the computer models on which the IPCC based the gloomy forecasts of a rapidly warming planet in its latest report, published in September, are diverging widely from reality.
You think!? They haven’t been close to correct for years. In fact, they can’t even recreate the past with any fidelity. Here’s the reality:
The pause means there has been no statistically significant increase in world average surface temperatures since the beginning of 1997, despite the models’ projection of a steeply rising trend.
According to Dr Hawkins, the divergence is now so great that the world’s climate is cooler than what the models collectively predicted with ‘five to 95 per cent certainty’.
Curry and Wyatt say they have identified a climatic ‘stadium wave’ – the phenomenon known in Britain as a Mexican wave, in which the crowd at a stadium stand and sit so that a wave seems to circle the audience.
In similar fashion, a number of cycles in the temperature of air and oceans, and the level of Arctic ice, take place across the Northern hemisphere over decades. Curry and Wyatt say there is evidence of this going back at least 300 years.
According to Curry and Wyatt, the theory may explain both the warming pause and why the computer models did not forecast it.
It also means that a large proportion of the warming that did occur in the years before the pause was due not to greenhouse gas emissions, but to the same cyclical wave.
‘The stadium wave signal predicts that the current pause in global warming could extend into the 2030s,’ said Wyatt. This is in sharp contrast with the IPCC’s report, which predicts warming of between 0.3 and 0.7C by 2035.
Wyatt added: ‘The stadium wave forecasts that sea ice will recover from its recent minimum.’ The record low seen in 2012, followed by the large increase in 2013, is consistent with the theory, she said.
So now we have a viable theory that doesn’t rely on forced and fudged numbers (or hiding the decline) and has a history of at least 300 years.
I imagine the “chicken little” crowd will ignore it as they ignore all studies that refute or at least question their insistence that man is the cause of any warming going on. After all, if they don’t, if they admit their wrong, how in the world can government use their power of taxation to literally create revenue out of thin air?
Of course they can’t. So they’ll ignore the new science and resort to calling those who are doing it and supporting it “deniers”, demonize them as ignorant neanderthals all the while conspiring to pass laws to relieve you of your money in the name of saving the world.
