Models get the core assumptions wrong– – the hot spot is missing

This is part of a series that Tony Cox and I are doing that references the most important points and papers, as a definitive resource about the evidence. The missing hotspot is not just another flaw in the theory, it proves the models are wrong: not just “unverified”, not just “uncertain”, but failed. Apologies to those who feel I harp on about this! This is a condensed review, squishing years of a scientific battleground down to it’s bare bones… — Jo

It is not well known that even the IPCC agrees that the direct effects of CO2 will only increase world temperatures by 1.2°C. All of the projections above that (3.3°C , 6°C etc) come from model projections based on assumptions of what water vapor and clouds will do (these are the feedback effects of the original 1.2°C).[i] Are the feedbacks correct?

If the IPCC models are right about the feedbacks, we would see a hot spot 10km above the tropics. The theory is that with more heat, more water will evaporate and rise, keeping relative humidity constant at all heights in the troposphere. The point has been conclusively tested with 28 million weather balloons since 1959.[ii]

Australian teachers — pick up your free copy of Ian Plimer’s new book

The Education Department and the CSIRO push their propaganda and scare our children with apocalyptic, unscientific scenarios.

They are even trying to target pre-schoolers. The ABC has accepted grants from the Climate Change Foundation to work the Climate Change message into ‘DirtGirl’, an ABC4Kids TV. Then there are demonstrations of bias like this from a school in Sydney.

They’re trying to train the next generation to “think” their way. We’d be mad to let them get away with it.

Thanks to the Gallileo Movement and donors, 300 FREE copies of Professor Ian Pilmer’s new book ‘How to get expelled from school’, are available to schools in Australia.

The Galileo Movement’s aim is to expose the unscientific claims made by climate change scientists and political attempts to unnecessarily control our freedom and future prosperity. If you are a teacher or you know one, you can help ensure that your local school library has a balance of books on climate change science.

Can you convince your Federal, State or Local member to talk the local school on your behalf?

The books are available to schools within [...]

The Travesty of the Missing Heat — deep ocean or outer space?

(See the Hammer link below, for more information on this graphic).

If there is one topic that trumps all others in climate science, it’s ocean heat.

If there is a planetary imbalance in energy, and Earth is acquiring more heat than it’s losing, we ought to be able to find that heat. Energy can not be created nor destroyed. It has to be somewhere.

On this Water-Planet, virtually every scientist agrees that the vast bulk of the extra energy ought be stored in the water. The oceans cover 70% of the surface, and are 4km deep; water has a high heat capacity (meaning it can store a lot of energy), and, because water flows quickly (unlike rock), turbulence and mixing can take that heat energy away from the surface.

Every skeptic (and taxpayer) ought to know that since 2003 (when we started measuring oceans properly) the oceans have been cooling: Douglass and Knox 2010.

Five years of planetary heating amounts to a massive amount of energy. That’s 2,000 days of the sun bearing down on an atmosphere with growing levels of CO2. According to the IPCC favored models, the extra heat stored should be 0.7 x [...]

The chemistry of ocean pH and “acidification”

The ocean acidification threat is a big can of worms. I asked Professor Brice Bosnich to help create a quick reference page on the chemistry and was pleased he could find the time to help. Here’s everything you wanted to know about the basics…

He explains what pH means, and points out that:

Ocean pH varies by 0.3 naturally. Claims of acidification since 1750 are based on dubious models and few observations.

There are reasons to assume that marine life will not be overly affected by an increase in ocean acidity due to atmospheric carbon dioxide:

Ocean life evolved and survived far higher levels of CO2 for millions of years in the past. Marine organisms actively create carbonate shells (using energy) which means crustacea, corals and molluscs aren’t automatically prey to pH changes in the same way that say a limestone rock would be. The world’s oceans may have warmed a mere 0.17C since 1955, hardly a significant threat to marine life.

We also find out that acidic water is added to the ocean from rainfall and floods (and he explains why raindrops will always be acidic).

There are more pressing threats. — Jo
