It’s hard to overestimate the influence of John and Hank Green on the Internet, particularly among people my age. John (who writes books for teenagers) and Hank (who maintains the website EcoGeek and sings songs about particle physics) run a YouTube channel that celebrates nerdiness. This Internet community is now a huge part of pop culture [...]

A growing body of research is showing that humans are likely causing more than 100% of global warming: without our influences on the climate, the planet would actually be cooling slightly. In 2007, the Intergovernmental Panel on Climate Change published its fourth assessment report, internationally regarded as the most credible summary of climate science to [...]

Also published at Skeptical Science This is a climate model: T = [(1-α)S/(4εσ)]1/4 (T is temperature, α is the albedo, S is the incoming solar radiation, ε is the emissivity, and σ is the Stefan-Boltzmann constant) An extremely simplified climate model, that is. It’s one line long, and is at the heart of every computer [...]

Apologies for my silence recently – I just finished writing some final exams that I missed for the AGU conference, so I’ve been studying hard ever since Boxing Day. I am working on a larger piece about climate models: an introduction to how they work and why they are useful. That will take about a [...]

Do not burn yourself out. Be as I am – a reluctant enthusiast… a part time crusader, a half-hearted fanatic. Save the other half of yourselves and your lives for pleasure and adventure. It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it [...]

A lot of great articles reflecting on the Durban talks have come out in the past few weeks, particularly in the mainstream media. Some of my favourites are Globe and Mail articles by Thomas Homer-Dixon and Jeffrey Simpson, The Economist writing that climate change, in the long run, will be more important than the economy, [...]

Cross-posted from NextGen Journal Following the COP17 talks in Durban, South Africa – the latest attempt to create a global deal to cut carbon emissions and solve global warming – world leaders claimed they had “made history”, calling the conference “a great success” that had “all the elements we were looking for”. So what agreement [...]

I went to a public lecture on climate change last night (because I just didn’t get enough of that last week at AGU, apparently), where four professors from different departments at my university spoke about their work. They were great speeches – it sort of reminded me of TED Talks – but I was actually [...]

Last week at AGU, I presented the results of the project Steve Easterbrook and I worked on this summer. Click the thumbnail on the left for a full size PDF.

For a long time I have struggled with what to call the people who insist that climate change is natural/nonexistent/a global conspiracy. “Skeptics” is their preferred term, but I refuse to give such a compliment to those who don’t deserve it. Skepticism is a good thing in science, and it’s not being applied by self-professed [...]
