160 years of cooling

Over at WUWT, guest blogger David Whitehouse from the Global Warming Policy Foundation research institute has a very insightful post about the recent lack of global warming. However, it is not only the last decade or two that has seen no warming. As a matter of fact, there has been no warming for the last 160 years. On the contrary, there has been a number of cooling episodes. Consider the following graph showing the global temperature according to the unadjusted HadCRUT3 series (from Wood for Trees). You can click on the graph to enlarge it.

This graph shows the global temperaure as a red curve, and a number of trends as straight lines of different lengths. These different trends are for various periods: 1850-1865, 1865-1875, 1875-1915, 1915-1920, 1920-1925, 1925-1930, 1930-1935, 1935-1980, 1980-1988, 1988-1995, 1995-june 1997, july 1997-2003, and 2003-2010. And every single one of them is negative. These trends together cover the entire period from 1850 to 2010, that is 160 years, and each of the trends shows a cooling. In many cases, it is a matter of the very strong cooling, and in a few cases a more modest cooling. This means that this entire period of 160 years it has been cooling.

Looking at the red curve, it might appear to the casual observer that in spite of all these negative trends, the global temperature has actually gone up. However, that is but an illusion created by the coincidence that each trend segment starts at a somewhat higher point than the previous trend segment. Hence, the apparent warming does not really exist. It is just a trick of the eye, which disappears when the data is subject to rigorous statistical analysis.

Some warmists may object and say that we should have computed the trend for the entire period. To that I respond: that is a really big cherry you are trying to pick there, Mister! Anyhow, such a long trend has no scientific meaning - it is but a line drawn by a ruler, a trick to hide the decline. And when I say that, I'm being awfully charitable.

So increasing levels of CO2 don’t cause increasing temperatures. How many negative counterexamples of a theory does it take to falsify it?

Guest post by John Carter: The Warmers are back

Today, I'm very proud to have a guest post by American congressman John Carter, a Republican from Texas. Well, strictly speaking it is not a guest post because I didn't really invite John to write this, I simply copied it from his web site, but I'm still very proud to have pasted his text here. And although I do not personally know John, it feels like I have known him all my life!

The Warmers are back.

They were thoroughly discredited just last year in the international "Climategate" scandal. The United Nation’s Intergovernmental Panel on Climate Change and their pals from the East Anglia Climatic Research Unit in Great Britain were caught red-handed, through their own email communications, to have intentionally falsified the scientific data on which they claim that human activity is a leading cause of global warming. Further, they were found to have hidden their own research results that showed world temperature not rising, but actually falling over the past several years.

The truth they tried to conceal from the world is that global temperature fluctuations are a normal earth cycle. We may or may not even be in a warming cycle. Even if we are, scientific evidence does not conclude that activity by man plays any significant role.

The reason for the lies is because the goal of these people is not to protect the environment, it is to implement a socialistic one-world government that has dictatorial control over every human activity, led by tyrannical liberal elites.

Global warming is simply a chicken-little scheme to use mass media and government propaganda to convince the world that destruction of individual liberties and national sovereignty is necessary to save mankind, and that the unwashed masses would destroy themselves without the enlightened global dictatorship of these frauds.

We do face a global threat. But it is not global warming, it is global tyranny from this crowd of liars – the Warmers.

Wise words indeed! Carter really nails it when he describes how the warmers are making stuff up in order to fool the gullible masses. You can read the rest of the guest post here.
