Nir's 2005 paper "On climate response to changes in the cosmic ray flux and radiative budget", available as pdf here, provides a solid case linking cosmic ray flux (CRF) variations to global climate change. The effect is consistent over hugely different timescales, using completely different indicators -- from cosmic sources of CRF at the Phanerozoic, to the shortest time scale of the 11-yr solar cycle. The fit is extraordinary. The statistics competent. The bottom line?
Thus, anthropogenic Read more [...] 28 com
The theory of this Israeli astrophysicist has gained traction as the great white hope of climate skeptics. Below are some sources of background reading.
Shaviv champions the solar-wind modulated cosmic ray flux (CRF) hypothesis, which was suggested by Ney, discussed by Dickenson, and furthered by Svensmark (see CO2 Science). Evidence consistes of correlations between CRF variations and cloud cover, correlations between non-solar CRF variations and temperature over geological timescales, as well Read more [...] 28 com
Dr Roy Spencer, has weighted in on Dessler et al 2008. Water-vapor climate feedback inferred from climate fluctuations, 2003-2008,
Whereas Dessler closes his paper firmly in the climate liberal camp.
 The existence of a strong and positive water-vapor feedback means that projected business-as-usual greenhouse gas emissions over the next century are virtually guaranteed to produce warming of several degrees Celsius. The only way that will not happen is if a strong, negative, and currently unknown Read more [...] 11 com
Ronald Reagan was born on the 6th of February 1911. If ever we were in need of wisdom from the man who changed the free world, its now. Below are some of my favorite Reagan quotes, relating to some of the madness going on around us.
Soros Says Crisis Marks End of Free-Market Model That Started Under Reagan

The following is an approximate propagation of uncertainty through Dessler et als. equation for estimating the strength of water vapor feedback λ. We have been looking at the error-bars in his recent paper Water-vapor climate feedback inferred from climate fluctuations, 2003-2008, not calculated in the published paper. Assumptions made are noted. Refer to wiki for propagation of error equations.
Here R is the top of atmosphere IR, q is the specific humidity and T is the temperature.

Detecting bias in research is not so difficult when you know what to look for. The conclusions are not justified by the data. Instead, the data may confirm, be consistent with, (or not inconsistent with) the conclusions. Working against this however are basic human motives on the part of the writer, to find novel and interesting approaches, find significant results when nothing is there, to be accepted by their colleagues, to get grants and be published.
According to Geoffrey Miller (The Mating Read more [...] 4 com
While Prof. David Karoly's guest post at RealClimate is admirably nuanced, he has graciously left some low-hanging fruit to take the stick to. He states:
1. Increases of mean temperature and mean maximum temperature in Australia have been attributed to anthropogenic climate change, as reported in the IPCC Fourth Assessment.
In a comment at ClimateAudit, Ian Castles remarked on a a similar temperature phenomenon attributed to David Karoly, but mysteriously dissapearing from the AR4:

Ian Castles organized a review of the Drought Exceptional Circumstances Report by two Accredited Statisticians, who also review my first report on the skill of the climate models.
The statisticians find inadequate validation of the models of drought, as well as suboptimal regionalization in the DECR. They also find my analysis lacked force, and so I have done additional analysis in line with their suggestions.
The last few posts in the series have consisted of reviews of an unsuccessful submission Read more [...] none

A review by independent Accredited Statisticians, Brewer and Other [KB09], suggested that some claims in the report â€œTests of Regional Climate Model Validity in the Drought Exceptional Circumstances Reportâ€ [DS08] were premature. Additional tests suggested by KB09 support the claim made in the original report of â€œno credible basis for the claims of increasing frequency of Exceptional Circumstances declarationsâ€.

Below are Peter Gallagher's thoughts on the reviews of the submission to AMM. Contrast this with ac's impressions that "To my reading the reviewerâ€™s criticisms are reasonable and pertinent." It goes to show, that reasonable and unrelated people can see things in different ways. Where is the resolvability of fact in the review process? Consensus?
Thanks for sending me these papers.

Mish reports on a massive secret audit of the major US banks. He raises some interesting questions, relevant to auditing and secrecy, and both in finance and in science.
Nearly 100 federal banking regulators descended on Citigroup in New York on Wednesday morning. Dozens more fanned out through Bank of America, JPMorgan Chase and other big banks across the nation.
There is no transparency and there are no details. Is this supposed to inspire confidence?

The Financial Times recently reported on the Australian bushfires, linking them to increases in greenhouse gases. We take another look at the data in the DECR and find Australia is getting wetter not drier:
Scientists say Australia, with its harsh environment, is set to be one of the nations most affected by climate change.
â€œContinued increases in greenhouse gases will lead to further warming and drier conditions in southern Australia, so the [fire] risks are likely to slightly worsen,â€ Read more [...] 16 com

A number of familiar tests, often used to evaluate the performance of models: R2 correlation, Nash-Sutcliffe efficiency and similarity of trends and return period, were reported here, noting not much evidence of skill in the DECR models compared with observations at any of these. I also said what a better treatment might entail but left that for another time:
The percentage of droughted area appears to be a â€™bounded extreme value, peaks over thresholdâ€™ or bounded POT statistic. The Read more [...] one
Posts over the next few weeks will be updates on the status of reviews myself and others have initiated of the Drought Exceptional Circumstances Report (DECR), by the CSIRO and Bureau of Meteorology (BoM).
It is prudent to subject your views to the rigors of peer review. It is the way to knowledge to search out feedback.
