"I've posted before (here and here) about the John Cook study that purports to find that 97% of climate scientists believe that humans are the main cause of global warming.
Now Richard Tol, a professor of the economics of climate change, has written a further critique of the Cook study.
Some have claimed that Cook et al. found a consensus on the dangers of climate change (Kammen, 2013) or on the need for climate policy (Davey, 2013). They investigated neither. Even some of the authors of the paper misrepresent its findings (Nuccitelli, 2014, Friedman, 2014, Henderson, 2014).Cook et al. took a sample of the academic literature and rated its contents. The raters were recruited through a partisan website (Cook et al., 2013) and frequently communicated with each other (Duarte, 2014). Their sample is not representative of the literature (Tol, 2014a). The sample was padded with large numbers of irrelevant papers (Tol, 2014a). For example, a paper on photovoltaics in Kenya (Acker and Kammen, 1996) was taken as evidence that climate change is caused by humans as was a paper on the coverage of climate change on US TV (Boykoff, 2008). Three-quarters of the "endorsing" abstracts offer no evidence either way (Tol, 2014a). Their attempt to validate the data failed (Tol, 2014a). An attempt to replicate part of the data failed too (Legates et al., 2013). The data show inexplicable patterns (Tol, 2014a) while the consensus rate suffers from confirmation bias (Cook et al., 2014a, Tol, 2014b).in sum, one of the most visible climate papers of recent years is not sound. Whereas previous critique could be interpreted as a lack of competence (Tol, 2014a), the later data release suggests that Cook et al., perhaps inadvertently, worked towards a given answer. This reflects badly on the authors, referees, editors and publisher. It also weakens the activists and politicians who cite Cook et al. in support of their position."
Just consider the following: the Speaker of the House currently receives an annual salary of $223,500, and will receive a payment of roughly that amount, depending on the years of service, for life. An annual payment of this magnitude amounts to about five times the average annual wage in the United States. But that’s not all. For those who have had different positions in Congress, their retirements can be augmented. For example, Nancy Pelosi will not receive $223,500 for life, but roughly double that. Why? Because she is a member of Congress, currently the House of Representatives’ Minority Leader, and a retired Speaker of the House. For purposes of computing retirement pay, Congress adds and accumulates. They do not net.
In addition to supporting members of Congress and civil servants, U.S. taxpayers support welfare recipients. And they support them lavishly, too. Hawaii, Massachusetts, and D.C. residents receive sizeable welfare payments (read: salaries). Indeed, the magnitude of these payments exceeds the average salary of an American teacher, as well as a soldier deployed in Afghanistan, by at least $10,000 per year.
The public can forget all the clap-trap they are hearing about austerity. Indeed, a fairly dull knife could cut billions of dollars from the U.S. government’s largess.
