Ice Age (not the movie)

It's been over a year since I wrote Stupid Letters, The Global Warming Scam, and Science? I Think Not! As you may recall, I've noted that the best predictor of Earth's climate is not CO2, but solar activity.

So, since a noble squirrel friend pointed me towards this article in the UK Daily Mail, I thought I'd make a quick post about it.
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.
of course, this can't be right, can it?
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.’

He pointed out that, in claiming the effect of the solar minimum would be small, the Met Office was relying on the same computer models that are being undermined by the current pause in global-warming.
So we have the battle of astronomers and climate scientists using actual data, against climate "scientists" who cling to their computer simulations. The points I think are worth learning from all of the brouhaha are:
  1. The Earth's climate is constantly changing. Global warming Climate Change is not something new.
  2. Despite our desire to have everything about us, not everything is about us.
That's not to say that I don't think we should respect the environment or conserve energy (I do), but simply that alarmist propaganda is just that - a manufactured crisis in order to create an opportunity to push an ideological agenda.
