The CBC is reporting on polling results pertinent to this fall’s federal election: CBC News poll takes snapshot of Canadians ahead of fall election. They say the cost of living was the top concern identified, followed by climate change. This suggests a familiar Canadian dynamic: being notionally concerned about climate change, but rejecting action on […]


Over the years I have written a variety of academic papers on various aspects of nuclear weapons and nuclear power: 1) Written for an undergrad international relations course at UBC and subsequently published in a journal and given an award: “The Space Race as ‘Primitive’ Warfare.” UBC Journal of International Affairs. 2005. p. 19-28. 2) […]


Conservatives have no more reason to want to destabilize the climate than anyone else, though the political right has largely become where those who deny the existence of or need to do anything about climate change can persist unrebuked and win converts.

The OCO was rebuilt at OCO-2, which has since collected data on the spatial distribution of carbon dioxide on Earth.

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 […]

I have written before about the cognitive and emotional (and insomniac) downsides of checking the news too often. It seems worth re-emphasizing how twitter is a worst-case scenario in this regard, at least for people more interested in developments in matters of public interest than developments in the lives of friends and acquaintances, where facebook […]


Blair King (whose blog bio says he has an “Interdisciplinary PhD in Chemistry and Environmental Studies”) is one of the people who had sent a tweet arguing that only people who use few or no fossil fuels can call for decarbonization and who I linked to this rebuttal post. He subsequently wrote his own response […]
