Just don't tell me the debate's over…
Check out Leonard “Spock” Nimoy presenting an episode of the “In Search Of…” series in the late 1970s about the changing climate – and the coming Ice Age. Stick with it to part 3 to hear the late Stephen Schneider spreading what one can only call Global Cooling Alarmism:

Global cooling ahead?
For some time now, the indications have been that solar activity and sunspot number are heading towards a minimum in the next few decades. Will it be a Dalton-style or a Maunder-style minimum? If the latter, we should be looking forward to significant cooling.
We reported on a recent press release from the Met Office a few days ago (“Solar decline “unlikely to offset greenhouse warming”: Met Office“), where the warmist spin was that reductions in solar irradiance were insignificant and would not halt CO2-induced global warming.
And yes, if you put on your AGW-blinkers, forget 90% of the science of solar physics, focus only on solar irradiance and ignore the plethora of indirect effects on the climate which are related to the Sun, that’s probably correct.
But now others are speaking out on this narrow interpretation:
The supposed ‘consensus’ on man-made global warming is facing an inconvenient challenge after the release of new temperature data showing the planet has not warmed for the past 15 years.
The figures suggest that we could even be heading for a mini ice age to rival the 70-year temperature drop that saw frost fairs held on the Thames in the 17th Century.
Based on readings from more than 30,000 measuring stations, the data was issued last week without fanfare by the Met Office and the University of East Anglia Climatic Research Unit. It confirms that the rising trend in world temperatures ended in 1997.
Notice how the data were released “without fanfare”, and consider how the data would have been released if they showed continued warming [here’s a clue, it would have been shouted from the rooftops]. As usual, inconvenient data is slipped out to avoid anyone noticing.
Meanwhile, leading climate scientists yesterday told The Mail on Sunday that, after emitting unusually high levels of energy throughout the 20th Century, the sun is now heading towards a ‘grand minimum’ in its output, threatening cold summers, bitter winters and a shortening of the season available for growing food.
Because cooling is really bad news compared to a gentle warming. So be careful what you wish for…
Solar output goes through 11-year cycles, with high numbers of sunspots seen at their peak.
We are now at what should be the peak of what scientists call ‘Cycle 24’ – which is why last week’s solar storm resulted in sightings of the aurora borealis further south than usual. But sunspot numbers are running at less than half those seen during cycle peaks in the 20th Century.
Analysis by experts at NASA and the University of Arizona – derived from magnetic-field measurements 120,000 miles beneath the sun’s surface – suggest that Cycle 25, whose peak is due in 2022, will be a great deal weaker still.
According to a paper issued last week by the Met Office, there is a 92 per cent chance that both Cycle 25 and those taking place in the following decades will be as weak as, or weaker than, the ‘Dalton minimum’ of 1790 to 1830. In this period, named after the meteorologist John Dalton, average temperatures in parts of Europe fell by 2C.
However, it is also possible that the new solar energy slump could be as deep as the ‘Maunder minimum’ (after astronomer Edward Maunder), between 1645 and 1715 in the coldest part of the ‘Little Ice Age’ when, as well as the Thames frost fairs, the canals of Holland froze solid.
Yet, in its paper, the Met Office claimed that the consequences now would be negligible – because the impact of the sun on climate is far less than man-made carbon dioxide. Although the sun’s output is likely to decrease until 2100, ‘This would only cause a reduction in global temperatures of 0.08C.’ Peter Stott, one of the authors, said: ‘Our findings suggest a reduction of solar activity to levels not seen in hundreds of years would be insufficient to offset the dominant influence of greenhouse gases.’
These findings are fiercely disputed by other solar experts.
‘World temperatures may end up a lot cooler than now for 50 years or more,’ said Henrik Svensmark, director of the Center for Sun-Climate Research at Denmark’s National Space Institute. ‘It will take a long battle to convince some climate scientists that the sun is important. It may well be that the sun is going to demonstrate this on its own, without the need for their help.’
Indeed so. Thanks to the Sun’s likely forthcoming decrease in output, we will have a real-world experiment to observe, which may finally reveal the level of influence our nearest star really has on our climate.

In a decade or two?
Rather than pointless efforts to stop the almost non-existent problem of CO2 caused warming, we should probably be preparing for the opposite, since many scientists are pointing towards a future sharp decline in global temperature caused by the unfortunate coincidence of three factors:
As Roy Spencer argues in his book, The Great Global Warming Blunder, the PDO may have significant effects on cloud cover, which may in themselves be sufficient to explain virtually all of the late 20th century warming, without any discernible effect from anthropogenic CO2. Add this to the fact that the sun is in the deepest slumber since the Dalton Minimum, and Icelandic volcanoes are kicking off and you have a recipe for significant global cooling.
All conjecture of course, but probably far more likely than the dire predictions of the IPCC’s incomplete and flawed climate models. So time to get your thermals out…

My denial is this big
Tony Abbott has stated a very simple fact that many others do not have the guts to state: the world has not warmed significantly since 2001, and may have even cooled. There seems nothing particularly controversial about that statement. The temperature data shows it clearly (if you look at the satellite record and ignore the surface record with its convenient manual “adjustments” that always seem to be upwards, that is). Even the Climategate emails acknowledge it – remember the quote “we can’t account for the lack of warming”?
But Penny Wong, the person most intimately acquainted with the ETS and climate change policy in Australia, just cannot deal with facts. Neither can enviro-loony Bob Brown, and both resort to spin and obfuscation in response. First off, here’s the Wong-bot:
“He is out there publicly talking about the world cooling when we have so many world leaders … going to Copenhagen because they are concerned about climate change,” she said.
“We see Mr Abbott talking about the globe cooling as the rest of the world is trying to work its way to tackling climate change.”
A gobsmacked [“gobsmacked”? Fine journalism there from Fairfax- Ed] Greens Leader Bob Brown said Mr Abbott’s comments would alienate conservatives.
“In a world where both big and small business understand the science of climate change and the need for appropriate action,” Senator Brown said.
Wong and Brown can’t handle the truth that the planet hasn’t warmed for a decade – in other words, they’re in denial.
