IPCC AR5: global warming more evident than ever

Last week, the Intergovernmental Panel on Climate Change (IPCC) released the first (and primary) instalment of its Fifth Assessment Report (AR5). Its key conclusions include: The Earth is accumulating heat. Heat-trapping greenhouse gases are rising: Atmospheric levels of carbon dioxide (CO2), methane, and nitrous oxide have reached levels unprecedented in at least 800,000 years because …

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.

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 …

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 …

Scientific Opinion versus Media Balance

Renegade Conservatory Guy has created an infographic showing the discrepancy between scientific opinion on global warming and public opinion. I think this speaks for itself.

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 …
