Scientific skepticism is healthy. Scientists should always challenge themselves to expand their knowledge and improve their understanding. Yet this isn't what happens in global warming skepticism. Skeptics vigorously criticise any evidence that supports man-made global warming and yet uncritically embrace any argument, op-ed piece, blog or study that refutes global warming.

So this website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?


Monckton Myth #10: Warming in the Pipeline

Posted on 11 February 2011 by dana1981

Monckton Myths (200 x 70 pixels)As part of an ongoing series looking at Christopher Monckton’s response to Mike Steketee and as a new addition to the Monckton Myths, this post examines Monckton’s arguments about the amount of warming remaining "in the pipeline" from the CO2 we've already emitted.  Monckton's point #23 in response to Steketee is mainly a misunderstanding of Steketee's argument:

Climate Data for Citizen Scientists

Posted on 10 February 2011 by D Kelly O

Guest post by Kelly O'Day from Climate Charts & Graphs

I find that charting climate trend data helps me to understand the interplay of climate factors more effectively than just reading an article or post . As an example, using online monthly climate agency data I made this chart to help me understand how the long term temperature trends are affected by major volcanic eruptions and  El Nino - La Nina events.

Dutch translation of The Scientific Guide to Global Warming Skepticism

Posted on 10 February 2011 by John Cook

Norwegian translation of Scientific Guide to Global Warming Skepticism The Scientific Guide to Global Warming Skepticism has been translated into Dutch. Many thanks to Stefaan Depraetere for the translation.

If anyone is interested in translating the Guide into another language, there are two documents to help you: a two-column Word document with all the English text in one column and a blank column to place the translated text, plus a PDF Overview of the Guide to clearly mark each section for translators.

Please download the Word document and email me back the document with translated text. I'll then insert the translated text into the existing design. But best first to contact me to ensure noone else is already working on your language (versions in French, German, Portuguese, Slovene and Swedish are currently in the works).

Voicing values and climate change

Posted on 9 February 2011 by Mark Edwards

A short piece for the general audience of RTR radio, Perth, Australia.
(listen to the original audio podcast)

There is a fundamental fault line that runs through the heart of the climate change issue in Australia.  Privately,we take it seriously while publicly we do almost nothing. The horrendous floods in Queensland last month provide a glimpse of the social, environmental and economic impact that climate change is having on the Australian economy.  And yet organisations, including governments and corporate businesses, are seemingly incapable of developing an adequate response to the problem.The Gillard government’s extraordinarily hypocritical reduction in climate change funding to pay for flood damage is an example of the fickle nature of government policies on this issue, and the private sector has shown no concerted leadership for tackling climate change.

So, you think that learning about climate change needs to be tedious?

Posted on 9 February 2011 by BaerbelW

Actually, that isn’t necessarily so if the information is gift-wrapped or disguised as a fun but not trivial climate-quiz! In the course of working as a voluntary zoo-docent, I have helped to put together several quizzes to pique visitors’ interest about specific topics like tigers, rhinos, the rainforests or right now apes. All of these quizzes contain general questions about the animals and areas but don’t shirk away from the hard themes like the dire straits these species and regions are in. Questions which come with striking visuals or comparisons work best to get people thinking. We’ve been using the quizzes as one element of various materials – some of it “hands-on” – on our touch-tables. If the visitors are interested to learn more, some of the questions and answers can then be explained in more detail.

Monckton Myth #9: Monckton vs Monckton on heat waves

Posted on 8 February 2011 by John Cook

It can be difficult debunking misinformation that contradicts itself. The problem is the shifting of goal posts presents a moving target. You could rebut one part of a person's argument and find yourself agreeing with them in another part. On the other hand, for a glass-half-full person, this lack of internal consistency might be seen as a useful resource. Why bother contradicting misinformation when the author contradicts himself. For example, in Monckton Skewers Steketee, Monckton presents a muddled series of thoughts on why climate change has nothing to do with extreme weather events. When talking about record hot weather, Monckton points out that while heatwaves happen, so too do cold snaps:

Crichton's 'Aliens Cause Global Warming'

Posted on 8 February 2011 by Alden Griffith

In 2003, Michael Crichton delivered a lecture at Caltech titled "Aliens Cause Global Warming". This lecture has since circulated widely and its arguments often come up in critiques of climate science. An excerpt was even published posthumously in The Wall Street Journal. I wish to comment briefly on two particular sections of the lecture: consensus and climate models.

Articgate: perpetuating the myth that Arctic sea ice has recovered

Posted on 7 February 2011 by John Cook

In 2009, former astronaut Harrison Schmitt submitted a white paper to NASA, Observations Necessary for Useful Global Climate Models. In this paper, Schmitt crams in an impressive number of skeptic arguments - including the argument that we're currently experiencing cooling:
