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 …

Climate change explained in 15 minutes

The other day I found this great TED video where blogger David Roberts explains the significance of increasing degrees of global warming:

Get ready for the carbon bubble

Remember the sub-prime mortgage bubble? The next economic bubble could be caused by investing in the unsustainable fossil fuel industry. The idea might sound incredible, but it results from our failure to seriously address the science of climate change. The science tells us we can’t burn all fossil fuels Fossil fuels formed over millions of …

Initial Reactions to the Carbon Tax: A First Step, but Improvement Needed

The carbon price package announced today is Australia’s first step in transitioning away from its current fossil fuel economy toward the renewable energy one we need to get to as soon as possible. There are significant improvements on Labor’s original Carbon Pollution Reduction Scheme (CPRS). But of course it’s far from perfect and it’s far …

Roundup of Carbon Tax Leaks

On Monday it was announced that the Multi-Party Climate Change Committee’s negotiations were sufficiently advanced for the full policy to be announced at noon tomorrow, followed by a Prime Ministerial broadcast at 6:30 PM. The MPCCC has reached agreement, and independent Andrew Wilkie (who is not on the committee) has indicated he will support the …

Christy Crock: Do the observations match the models?

I wrote this post for Skeptical Science. At the recent US House of Representatives Committee on Science Space and Technology climate hearing, the Republicans called Dr. John Christy as an expert witness testifying against the global warming consensus. Unfortunately, Christy spent his time repeating a long list of climate myths, including the common contrarian refrain …

Zero Carbon Australia: We can do it

I wrote this post for Skeptical Science. My recent post about long-term CO2 targets was rather doom-and-gloom: I concluded that we must phase out fossil fuels to keep the climate in the range that humans have experienced. The good news is that action on this scale is not only possible but surprisingly feasible. Last year, …

Climate Emergency: Time to Slam on the Brakes

I wrote this post for Skeptical Science as a basic rebuttal of the argument “It’s not urgent”. Global warming is an increasingly urgent problem. The urgency isn’t obvious because a large amount of warming is being delayed. But some of the latest research says if we want to keep the Earth’s climate within the range …

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 …

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 …
