The Question: Do increasing amounts of CO2 in the atmosphere pose an unacceptable risk of a catastrophic change in earth’s temperature in the future?
Of 1022 people polled, 55% agreed and 31% opposed (including the 19% who strongly opposed). Nearly half, or 45% are not convinced a catastrophe is on the way due to carbon dioxide. [...]
Released today. Four independent scientists respond in detail to the evidence that government scientists claim shows that carbon dioxide causes significant global warming. The real debate continues. After the return fire from the skeptical experts, there was not a single point left standing.
More muddy thinking. Once again, a politico-journalist writes about science and misses the point. Science is not like law, politics or sport: there is no umpire, no judge, no boss who sets the rules (at least not one you can interview). Opinions don’t control the climate, yet Mike Steketee makes the basic error of elevating [...]
Finally, the question we’ve all wanted to ask of the people in power: Where’s the evidence?
Senator Fielding holds a crucial vote on the proposed Emissions Trading Legislation. Fielding and four independent scientists faced the Minister for the Climate Change and Water, Penny Wong, The Chief Scientist, Penny Sackett, and Professor Will Steffen, director of the [...]
Undoubtedly the best summary of the current state of affairs is the SPPI monthly CO2 report. The April report contains news that—if there was a free and high quality media—would have generated headlines like these (well, sort of—you get the idea).
Any investigative journalist who was doing their job only had to Google for the other [...]
Just as the great bull run that could have no end, ended, another unthinkably big bubble quivers. Technical indicators are quietly being tripped that suggest the bull run in global temperatures may be toying with a reversal. Could another large human institution dependent on complex models be headed for it’s ‘Lehman Bros’ moment?
This must be it, surely, the point where being a skeptic has more scientific cachet than being a believer. The trickle is becoming a flood. We are reaching the stage where independent scientists will want to make sure they are known to be on the skeptical side of the fence.
This is vintage spinmeister-Tim. Overall he claims I’m deluded, confused, constantly repeating discredited arguments, “doesn’t even know what the hot-spot is”, and “doesn’t understand how the greenhouses gases warm the planet”. But when it comes to backing up the giant patronizing put-downs, it amounts to nit-picking phraseology; irrelevant points; straw men; his own false understanding of what a fingerprint is; and then an own goal when he drops in a graph that shows that the hot-spot is indeed missing.
Leo Elshof from Arcadia University in Nova Scotia* has written to me asking that I put a comedy disclaimer on the Skeptics Handbook, and otherwise threatens to ridicule me at international conferences and set the media onto me. The email is here and my reply is below. What have our universities sunk too?
See Leo’s scorecard on logic and reasoning.
Science based ideas are falsifiable, whereas religious ones are not (thanks Karl Popper). The acid test for climate scientists: “What evidence would convince you that carbon was not significant?”
Evidence means observations, made by people at some time and place. Things you can see, hold, hear and record. Computer models are not, and can never be evidence.
The gap between real world data and thermometers is a make-or-break issue for the AGW theory. The models predict a hot-spot in the atmosphere above the tropics, but the weather balloons (called radiosondes) can’t find any sign of it. Most claims that the hot-spot has been found are not providing any new data, they are [...]
The ‘Hotspot’ is crucial to the climate debate.
If greenhouses gases are warming the planet that warming will happen first in the cold blob of air 8-12 km above the tropics. It’s freezing cold up there, but it ought to be slightly less freezing cold thanks to greenhouse gases. All 20-odd climate models predict warming there [...]
I want to lift the debate above the mud-slinging, pathetic ad hominem attacks, and specious argument by authority. The basic rules of logic and reasoning have been known since the Greeks. Educated adults ought to do better. Maybe one day, national curriculums will too.
