UPDATE: In the comments, Baldrick provides a timely reminder of Dr Karl’s activist past, in that he was a Senate candidate in 2007 for the Climate Change Coalition, which was “formed in 2007 with a view to accelerate action by politicians from all parties on global warming and climate change.” He lost, as did all the other CCC candidates…
As any fule kno, every science presenter on the ABC is a fully paid-up climate alarmist. Robyn Williams, Bernie Hobbs, the Catalyst team, Adam Spencer and of course, Dr Karl Kruszelnicki himself, all plug the same consensus line, without any proper scientific scepticism.
But because of the 16-year temperature stasis that nobody wants to acknowledge, Dr (for a doctor he is*) Karl resorts to spouting krap:
Even before this report was released, some of the news media (such as the Daily Mail in the United Kingdom) recklessly claimed that this latest IPCC report revealed that global warming was over — and that in fact, the world was now cooling. This was very wrong.
Krap. The four major temperature series, GISS, HadCRUT, UAH and RSS (take note, Dr Suzuki) all show either stasis, imperceptible warming or cooling (see image below). And whether global warming is “over” or not is irrelevant – that’s just a tabloid newpaper making a story.
The real issue is why there has been such a divergence between models and real-world temperature. Despite fudging the graph in the IPCC Summary for Policymakers to give the impression that the models are still on track, the truth is that the models have spectacularly failed to predict the current stasis in global temperatures. Climate sensitivity to CO2 has been overestimated and natural forces ignored.
For one thing, nine of the 10 hottest years on record have happened in the last decade.
True, but irrelevant. Yes, the planet is warming, and has been for a couple of centuries, so it’s no great surprise that each decade is, generally, warmer than the last. The old “on record” chestnut is wheeled out, despite the fact that records barely cover 150 years. Dispassionate? Krap!
The trouble is, the surface of our planet has many many square metres. So that extra heat reflected back down to the ground is roughly equivalent to exploding a few hundred thousand Hiroshima-sized nuclear weapons in our atmosphere — every day.
This is recycled krap. Recycled by Dr Karl, from John Cook of Un-Skeptical Pseudo-Science, who in turn recycled it from James Hansen. Despite sounding terrifying, because the Sun is so powerful and the Earth so huge, this amount of energy approximates to half a watt per square metre (your average light globe is 60 watts), which would be lost in the downwelling radiation of approximately half a kilowatt. Cheap alarmist krap.
The overwhelming majority of the heat trapped by the extra carbon dioxide in our atmosphere enters the oceans.
Since 2007, we have been monitoring the oceans with small drifting oceanic probes — ARGO probes. Today, there are some 3,600 of these robotic probes in the oceans of the world. They continuously float up and down, rising to the surface and then diving down to a depth of 2 kilometres on a roughly 10-day cycle.
These ARGO probes have measured the heating of the oceans caused by that 93.5 per cent of the heat energy reflected back down by the carbon dioxide in the atmosphere. It turns out that about two thirds remains in the upper ocean between the surface and a depth of 700 metres, while the remaining one third of that heat energy goes deeper into the ocean — between 700 and 2000 metres.
Dr Karl trots out the buzzword du jour (see yesterday), ocean heat. The dog ate my warming. They seek it here, they seek it here, they seek it everywhere. Everywhere it can’t be measured, that is.
The ARGO probes have been around less than a decade, and the changes in temperature are of the order of a few hundredths of a degree. But here’s a thought – perhaps the warming over the last twenty years was caused by the oceans releasing heat (that couldn’t be measured) into the atmosphere, and was nothing to do with CO2?
Verdict: a kolourful kornukopia of klimate krap from Dr Karl (enough with the K’s – Ed)
