On the plus side, there's no reason for William M. Connolley to comment here anymore

Atmospheric science is on the side of the so called “sceptics”. The actual planetary measured warming due to the increase in atmospheric carbon dioxide is lower than the lowest IPCC model predicted warming. All of the warming is it at high latitudes where it was caused the biosphere to expand.
The fact that actual planetary warming is less than the lowest IPCC model prediction and is found only at high latitudes logically supports the assertion that the planet’s response to a change in forcing is to resist the change (negative feedback, planetary clouds in the tropics increase reflecting more sunlight in to space) rather than to amplify the change (positive feedback) due increased water vapour in the atmosphere.
Analysis of top of the atmosphere radiation changes Vs changes in planetary temperature also support the assertion that planetary clouds increase in the tropics thereby reflecting more sunlight off into space thereby resisting forcing changes rather than amplifying them.
Trillions of dollars are being proposed to be spent on boondoggle schemes which will not significantly reduction carbon dioxide increases but will have significant negative effects to the environment and to humanity. An example is the EU and US mandated conversion of food to biofuel (massive loss of tropic forest and unsustainable increase in the cost of food).
Western countries do not have trillions of extra tax payer funds to spend on irrational policy schemes that will damage the environment and result in starvation and malnutrition.
Carbon dioxide is not a poison. Plants eat CO2. A doubling of CO2 increases cereal yields by 30% to 40%. Plants make more effective use of water when CO2 rises which reduces desertification. The increase in atmospheric CO2 is unequivocally a significant net benefit to the biosphere and to humanity. Crop yields are and will continue to increase. There is and will be increased net precipitation. The biosphere expands when the planet warms with most of the warming occurring at high latitudes. That is a fact.
Science is unequivocally on the side of “sceptics”. No rational person would support trillion dollar boondoggle schemes.
The extreme AGW issue is a mania, the madness of crowds.

“The problem for global warming supporters is they actually need for past warming from CO2 to be higher than 0.7C. If the IPCC is correct that based on their high-feedback models we should expect to see 3C of warming per doubling of CO2, looking backwards this means we should already have seen about 1.5C of CO2-driven warming based on past CO2 increases. But no matter how uncertain our measurements, it’s clear we have seen nothing like this kind of temperature rise. Past warming has in fact been more consistent with low or even negative feedback assumptions.”
Richard Lindzen,
“It has long been observed that global warming offers opportunities for a huge number of interests to exploit and that the eagerness to exploit the issue has led to a remarkable corruption of institutions – public, private, and academic. In a set of cogent and well-written contributions, Climate Coup documents what is happening intelligently and in depth. There is no need for indignation in the contributions: the situation speaks for itself. One can only hope that the ordinary citizens of both the developed and developing worlds, who are the primary victims of all the Canute-like efforts to control climate, will take notice.

On the Observational Determination of Climate Sensitivity and Its Implications
We estimate climate sensitivity from observations, using the deseasonalized fluctuations in sea surface temperatures (SSTs) and the concurrent fluctuations in the top-of-atmosphere (TOA) outgoing radiation from the ERBE (1985-1999) and CERES (2000-2008) satellite instruments. Distinct periods of warming and cooling in the SSTs were used to evaluate feedbacks. An earlier study (Lindzen and Choi, 2009) was subject to significant criticisms. The present paper is an expansion of the earlier paper where the various criticisms are taken into account. The present analysis accounts for the 72 day precession period for the ERBE satellite in a more appropriate manner than in the earlier paper. We develop a method to distinguish noise in the outgoing radiation as well as radiation changes that are forcing SST changes from those radiation changes that constitute feedbacks to changes in SST. We demonstrate that our new method does moderately well in distinguishing positive from negative feedbacks and in quantifying negative feedbacks. In contrast, we show that simple regression methods used by several existing papers generally exaggerate positive feedbacks and even show positive feedbacks when actual feedbacks are negative. We argue that feedbacks are largely concentrated in the tropics, and the tropical feedbacks can be adjusted to account for their impact on the globe as a whole. Indeed, we show that including all CERES data (not just from the tropics) leads to results similar to what are obtained for the tropics alone – though with more noise. We again find that the outgoing radiation resulting from SST fluctuations exceeds the zerofeedback response thus implying negative feedback. In contrast to this, the calculated TOA outgoing radiation fluxes from 11 atmospheric models forced by the observed SST are less than the zerofeedback response, consistent with the positive feedbacks that characterize these models. The results imply that the models are exaggerating climate sensitivity. ….
….However, warming from a doubling of CO2 would only be about 1oC (based on simple calculations where the radiation altitude and the Planck temperature depend on wavelength in accordance with the attenuation coefficients of wellmixed CO2 molecules; a doubling of any concentration in ppmv produces the same warming because of the logarithmic dependence of CO2’s absorption on the amount of CO2) (IPCC, 2007). This modest warming is much less than current climate models suggest for a doubling of CO2. Models predict warming of from 1.5oC to 5oC and even more for a doubling of CO2. Model predictions depend on the ‘feedback’ within models from the more important greenhouse substances, water vapor and clouds. Within all current climate models, water vapor increases with increasing temperature so as to further inhibit infrared cooling. Clouds also change so that their visible reflectivity decreases, causing increased solar absorption and warming of the earth….

“I’ve run across Mr Connolley on several blogs and must admit that I’ve never won an argument with him. When I point out facts contrary to his assertion, he goes away.”
Sounds like a win to me.
