An insight for every school textbook on climate: '...we concluded that the global warming alarm is an anti-scientific political movement.'

Schools everywhere have been exposed to, or even immersed in, the ill-founded alarm over CO2 in the atmosphere.  It will take some time to get it out of school textbooks and out of the 'off-the-shelf', 'ready-to-go' section of political spin for sundry opportunists in politics and finance.  The paper quoted below can but help with this progress.

'Research to date on Forecasting for the Manmade Global Warming Alarm
Testimony to Subcommittee on Energy and Environment Committee on Science, Space and Technology – March 31, 2011 (Rev)

Abstract
The validity of the manmade global warming alarm requires the support of scientific forecasts of (1) a substantive long-term rise in global mean temperatures in the absence of regulations, (2) serious net harmful effects due to global warming, and (3) cost-effective regulations that would produce net beneficial effects versus alternatives such as doing nothing.

Without scientific forecasts for all three aspects of the alarm, there is no scientific basis to enact regulations. In effect, it is a three-legged stool. Despite repeated appeals to global warming alarmists, we have been unable to find scientific forecasts for any of the three legs.

We drew upon scientific (evidence-based) forecasting principles to audit the forecasting procedures used to forecast global mean temperatures by the Intergovernmental Panel on Climate Change (IPCC) –leg “1” of the stool. This audit found that the procedures violated 81% of the 89 relevant forecasting principles.

We also did an audit of the forecasting procedures used for two papers that were designed to support proposed regulation related to protecting polar bears – leg “3” of the stool. On average, these procedures violated 85% of the 90 relevant principles.

The warming alarmists have not demonstrated the predictive validity of their procedures. Instead, their argument for predictive validity is based on their claim that nearly all scientists agree with the forecasts. Such an appeal to “voting” is contrary to the scientific method. It is also incorrect.

We conducted a validation test of the IPCC forecasts based on the assumption that there would be no interventions. This test found that the errors for IPCC model long-term forecasts (91 to 100 years in the future) were 12.6 times larger than those from an evidence-based “no change” model.

Based on our analyses, we concluded that the global warming alarm is an anti-scientific political movement.'

Classroom Conundrums of Contradictory Climate Confusions: what are you going to tell them about the effects of climate change?

The sloppy science that led to the IPCC and to the construction and amplification of the CO2-scare is in such a poor state that those folks who study impacts are having a hard time of it.  Such people form the majority of the IPCC participants, only a few dozen of which are at all engaged with what drives climate change.

Steve Goddard has just published an updated list, thanks to a poster called Jimbo, of apparently contradictory conclusions.  Also published by Pierre Gosselin.  For example:

Amazon dry season greener
Amazon dry season browner

Avalanches may increase
Avalanches may decrease – wet snow more though

Bird migrations longer
Bird migrations shorter
Bird migrations out of fashion

Boreal forest fires may increase
Boreal forest fires may continue decreasing

Chinese locusts swarm when warmer
Chinese locusts swarm when cooler

Columbia spotted frogs decline
Columbia spotted frogs thrive in warming world

Coral island atolls to sink
Coral island atolls to rise

These, and the other links provided, are all to peer-reviewed literature ('but is it peer-reviewed?' was one of the spin options used by crisis-CO2 campaigners when challenged, but it is heard less often now that the IPCC has been exposed as relying very heavily on distinctly non-peer-reviewed literature).

It might be easier to tell your class that not only has climate science been degraded and poisoned by the IPCC activists, but much of the rest of the IPCC, the stuff on consequences, is in a bit of a mess too.

An earlier verion of the list was noted here in February: http://climatelessons.blogspot.com/2011_02_10_archive.html
