What is the major effect of anthropogenic global warming (AGW)? Below are some articles to give you a hint.

1. Santer Refuses Data Request, perhaps the most leading climate researcher apart from James Hansen, testily obstructing science.

I gather that you have appointed yourself as an independent arbiter of the appropriate use of statistical tools in climate research. Rather that “auditing” our paper, you should be directing your attention to the 2007 IJoC paper published by David Douglass et al., which contains an egregious statistical error.

Please do not communicate with me in the future.
Ben Santer

I sent the following FOI (Freedom of Information) request today to NOAA:

2. There is another hint in the title of this article from Bloomberg: Fed Defies Transparency Aim in Refusal to Disclose

Fed Chairman Ben S. Bernanke and Treasury Secretary Henry Paulson said in September they would comply with congressional demands for transparency in a $700 billion bailout of the banking system. Two months later, as the Fed lends far more than that in separate rescue programs that didn’t require approval by Congress, Americans have no idea where their money is going or what securities the banks are pledging in return.

“The collateral is not being adequately disclosed, and that’s a big problem,” said Dan Fuss, vice chairman of Boston- based Loomis Sayles & Co., where he co-manages $17 billion in bonds. “In a liquid market, this wouldn’t matter, but we’re not. The market is very nervous and very thin.”

Bloomberg News has requested details of the Fed lending under the U.S. Freedom of Information Act and filed a federal lawsuit Nov. 7 seeking to force disclosure.

3. OK, here is another hint from a skeptical commenter Ken Gregory (the answer is the opposite of Ken’s behaviour).

The data is from the NOAA Earth System Research Laboratory here: http://www.cdc.noaa.gov/cgi-bin/Timeseries/timeseries1.pl The data sent to Miskowczi was annual, with area weighted grids. To get annual data, select: Seasonal Average First month: Jan Second month: Dec For global data, select: Latitude: 90, -90 Longitude: 0, 360 The spreadsheet I sent to Miskowczi, with a few graphs added later, is here: http://members.shaw.ca/sch25/Ken/Optical%20Depth%20Data.xls

4. Still haven’t got the answer?
