Figure from my 2009 blog post, showing why delaying the global peak year for greenhouse gas pollution emissions means having to cut emissions much faster in the 2020s and 2030s to achieve the same temperature target: Tweeted by Greta Thunberg today: All this delay mutually reinforces the risks of catastrophes. People keep investing in fossil […]


In their 2019 Financial System Review the Bank of Canada identifies assessing climate-related risks as an activity they have started to undertake. The CBC reports: Climate change threatens ‘both the economy and the financial system,’ says Bank of Canada

Perhaps a central virtue for the world of the future will be self-denial, and specifically channeling covetous feelings toward sustainable ends: not collecting 10,000 Barbie dolls or flying into low Earth orbit, but doing instead things that will enrich and distinguish you in the community without heavy ecological effects, like writing, making art, and theatre. […]


This Montreal Gazette story opens with a line which I expect will become increasingly commonly heard as climate change impacts worsen: “Premier François Legault said Sunday it might be necessary to force people in flood zones to move away to avoid taxpayers having to constantly pay to repair their homes.” That seems sure to be […]


I was fortunate to be born in a time and place where everyone told us to dream big; I could become whatever I wanted to. I could live wherever I wanted to. People like me had everything we needed and more. Things our grandparents could not even dream of. We had everything we could ever […]


The election playing out in Alberta seems to have a lot in common with what has been happening with the federal Liberals, at least for those who see the urgency of decarbonizing to control climate change. There is a semi-progressive government that thinks that it has strong climate credentials because it has a long term […]


Today I was at a conference on “Building a Post-Carbon Future” by 2050. It was certainly not bad, but I felt there was a huge disjoint between the Paris Agreement targets frequently referenced (to keep global warming to less than 1.5–2.0 ˚C above pre-industrial levels) and the scale and ambition of the policies and actions […]


The Pembina Institute has released a new interactive tool that lets anybody test out alternative approaches to setting energy policy for Alberta, in sectors including transport, buildings, electricity generation, and agriculture. It doesn’t allow a huge amount of ambition. For instance, the only bitumen sands policy option is the 100 megatonne cap which the Alberta […]

At the end of January, Middlebury College (home institution of founder Bill McKibben) committed to fossil fuel divestment as part of a four-part response to climate change. As far as I know, this is the first university which had formally said no to a divestment campaign and has since been brought around to saying […]


The CBC is reporting today that the oil production cuts enacted by the NDP provincial government to try to raise fossil fuel prices have made oil transport by rail less viable. The possibility of exporting the bitumen sands by rail when pipeline capacity is exceeded has highlighted how fossil fuel advocates take climate change inaction […]
