Scientific Guide to Global Warming Skepticism

The Skeptical Science team (which includes myself) have recently completed a 16-page booklet called The Scientific Guide to Global Warming Skepticism. (Actually it was completed a fortnight ago, but I forgot to link to it at the time. Anyway, better late than never.) To quote John Cook’s blog post launching the Guide: Scientific skepticism is …

The Fake Scandal of Climategate

This post was written for Skeptical Science as the first part of a series on the fake scandal of Climategate. It’s bad enough that global warming contrarians are successfully misleading the public by propagating misconceptions about climate science. But recently it has become popular to attack climate scientists themselves, to accuse them of fraud and …

Increasing southern sea ice

This post was written for Skeptical Science as a “basic rebuttal” to the argument “Southern sea ice is increasing”. Sea ice around Antarctica has increased over the few decades that satellites have been measuring sea ice extent. First of all, it’s worth remembering that sea ice is not to be confused with land ice. This …

Americans Know Nothing About Climate Change

A new survey of 2,030 American adults (weighted according to demographics and political party allegiance) confirms what previous surveys have suggested: that the American public’s understanding of climate change is dismal. The researchers graded the participants based on percentage of questions answered correctly (although some questions were harder than others). A majority, 52%, received an …

Do the IPCC use alarmist language?

This post was written for Skeptical Science. Graham Wayne has recently written rebuttals to “The IPCC consensus is phony” and “IPCC is alarmist”. But, you might say, that’s only half the story – do the IPCC present their conclusions in an alarmist way? There are many different ways you might look at this, but one …

Skeptical Science posts

I haven’t been posting very often recently, and one reason is that I’ve been busy writing for another climate blog called Skeptical Science which, unlike mine, actually has a readership. Skeptical Science is run by John Cook, and basically the core of the site is an increasingly comprehensive database of rebuttals to the arguments of …

Global Warming Contrarians Part 7: State of the Climate

Claim: There’s no evidence that the global climate is warming. Why worry about a problem that’s invisible? Fact: Just about any aspect of climate you care to look at does show signs of global warming. The US National Oceanic and Atmospheric Administration have recently released their 20th annual State of the Climate report. The report …

Global Warming Contrarians Part 1.1: Amateur Temperature Records

After a two-month hiatus, I’ve finally completed the next installment in my increasingly non-linear series of posts examining the (mostly bad) arguments against the reality of global warming. Originally I had planned out a sort of arc of subjects to cover, but as I learn more about climate science, I find I want to go …

Global Warming Contrarians Part 2.1: Cooling Trend or Noise?

In Part 2 of this series of posts examining the (mostly bad) arguments against the reality of global warming, I debunked the oft-heard claim that global warming stopped in 1998. Basically, the people who make that claim are just joining endpoints, rather than looking at the trend from 1998 to now. But there is a …

Global Warming Contrarians Part 6: Global Cooling in the Mid-20th Century

Here, at last, is the much-delayed sixth instalment in my ongoing series of posts on the (mostly bad) arguments that contrarians make against global warming. (A list of earlier parts in the series can be found here.) In this post, I want to clear out of the way one more factoid that contrarians hold up …
