		<title>Independent Confirmation of Beenstock&#8217;s Theory</title>
		<description><![CDATA[Beenstock&#8217;s radical theory needs to be tested.  As discussed here, he proposed that it is the change in greenhouse gases (dGHGs) not absolute values, that produce global warming.  A simple test is to develop linear regression models predicting temperature, with and without GHG and dGHG.  If Greenstock&#8217;s theory is correct, then models [...]]]></description>

		<title>Cointegration Summary</title>
		<description><![CDATA[It’s incredible that a global warming theory could agree with both the IPCC (discernable anthropogenic influence) and the sceptics (low long term risk from emissions) but there you are.  The analysis of Greenstock suggests it is not the amount of greenhouse gasses, particularly CO2, in the atmosphere that contributes to global warming, but the [...]]]></description>

		<title>Cointegration</title>
		<description><![CDATA[So now the fun starts.  We have established the integration order of the variables in the RadF file, we impose the rule that only variables of the same order can be combined, and in particular that they cannot be cointegrated with temperature which is I(1).  In this case all the anthropogenic variables in [...]]]></description>

		<title>Integration Order of RadF.txt</title>
		<description><![CDATA[The test of integration order from the previous post is applied to the major atmospheric forcings used in the GISS global climate models in recent years. These are available for 1880 to 2003 in a file called RadF.txt  The codes for the forcings are self explanatory:  W-M_GHGs,   O3,  StratH2O,  [...]]]></description>

		<title>Cointegration Primer II</title>
		<description><![CDATA[Here we generate and test a number of series with different integration order I(n) and polynomial order O(n).  The test is the Augmented Dickey Fuller test, one of the most well known of the unit root tests.  Beenstock used three tests, because the tests for unit roots are known to have low power.

		<title>Cointegration Primer</title>
		<description><![CDATA[A draft of a paper by Beenstock and Reingewertz has surfaced in the blogosphere, but there seems to be confusion about what unit roots and cointegration are, and I can’t find anywhere on the web that explains them simply for the average Joe.  Given one can’t understand the paper without a good grasp of [...]]]></description>

		<title>Vindication</title>
		<description><![CDATA[A rash of stunning turnarounds have vindicated years of effort by climate sceptics.  The day after ClimateGate broke I made three predictions:
. Disband the entire Federal Department of Climate Change along with all the individual State Departments of Climate Change. 
. Vote down the Emissions Trading Scheme Legislation.  
. Cancel Copenhagen.   [...]]]></description>

		<title>Hyperbole</title>
		<description><![CDATA[From Nature (see http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo761.html):
&#8220;The precipitation anomaly of the past few decades in Law Dome is the largest in 750 years, and lies outside the range of variability for the record as a whole, suggesting that the drought in Western Australia may be similarly unusual.&#8221;
Climate science has a colorful history of hyperbole: hurricanes, droughts, floods, fires, [...]]]></description>

		<title>Review of Antarctic Snowfall</title>
		<description><![CDATA[A recent Nature paper we have been reviewing, claims recent snowfall at Law Dome, Antarctica and the drought in Western Australia &#8220;lies outside the range of variability for the record as a whole&#8221;.  Being about precipitation (often more important to us than temperature), and claims of evidence of AGW causing drought, its interesting.
