Alarmism: the excessive or exaggerated alarm about a real or imagined threat.

Australia’s Chief Scientist says we’ve got five years to save the world from disastrous global warming. Who can argue with a Chief Scientist? Well, given that the Chief Scientist made that claim nearly five years ago, and there has not been disastrous warming but on the contrary no significant temperature increase for around 16 years, I’d say the answer is anyone who can read and think!
The then Chief Scientist, Prof Penny Sackett, made the remark in December 2009.
The Intergovernmental Panel on Climate Change (IPCC) fifth assessment report says that the mean temperature of the planet has increased by 0.8 of a degree since the late nineteenth century. Therefore, the climate is warming. Moderately.
What then is with the continuation of exaggerated and alarmist claims and predictions? Why does the mainstream media generally give them so much publicity? (Rhetorical question, I know: the sensational headline sells papers and attracts viewers).
The IPCC’s most recent report accepts that there has been a pause or hiatus but does not see this as indicative of a reversal of the warming trend long-term.
The way to explain the pause is to allow scientific debate and argument, free of vilification. It may be that the increase of CO2 emissions to record levels and the lack of significant increase in warming do indeed point to a flaw in the original hypothesis that sees greenhouse gases caused by human industrial activity as the main driver of the warming since the 1880s. Or maybe not.
Perhaps there is something to be said for the new hypothesis that the heat is being absorbed by the oceans. This is plausible and testable; though according to a recent NASA study based on satellite observation and direct temperature measurement of the upper ocean (the deep ocean is difficult to measure, say the scientist authors): “The combination of satellite and direct temperature data gives us a glimpse of how much sea level rise is due to deep warming. The answer is – not much”.

Al Gore’s sci-fi ‘documentary’ ‘An Inconvenient Truth’ was screened in just about every primary school, high school and town hall in Australia – and in many other countries too. Counterpoints were rarely, if ever, offered. But his iconic portrayal of huge tidal waves swamping Manhattan was utterly unscientific, mere alarmism. They find no basis in the IPCC assessments, which put sea level rises at 0.26-0.55 meters (10-22 inches) by 2100 under a low emissions scenario and 0.52-0.98 meters (20-39 inches) under a high emissions scenario. Is this really headline grabbing and catastrophic? Why can’t policies of adaptation be effective and the most practicable response?
The former Chief Scientist should feel embarrassed at what she said nearly five years ago.
Having said that, fossil fuels really are so C19th and C20th. But that still makes them more up-to-date than medieval windmills.

The left looks to the future. That’s what attracted me to it more than 40 years ago. You know, stuff like flying cars and holidays on the moon. Karl Marx meets the Jetsons. No, I mean it!
The problem is that pure research hardly happens any more because the needs of capital come first. There’s no profit in mucking around with ideas and experiments with no short- or medium-term marketable objective.
Change this system to one in which social need, fun and fantasy are the raison d’etre and who knows what humans will come up with?
