Climate scientist, prof, writer, speaker, aquatic mammal, sorry for dragging sand in the house. Once upon a time, I enjoyed this site. Moved on to new shores.

Climate change is a failure of the imagination. For years, people struggled to believe it is real or would impact our lives. Now many struggle to believe we can solve the problem. My TEDx talk is about the path to overcoming doubts and embracing solutions. youtu.be/CZ_MPbjA78I

In talking about climate change, we pay lots of attention to daytime temperature records. We're also setting nighttime records (1/4)

Definitely would not have predicted that the only player remaining from the Raptors championship team seven years later would be Kawhi Leonard.

アルテミス1のオリオン宇宙船の大気圏再突入動画、20倍速にしてみました。25分も見てられないという方はどうぞ。1分15秒です。Credit: NASA

アルテミス2のオリオン宇宙船が日本時間の明日朝、大気圏に再突入して帰還します。 動画はアルテミス1での無人のオリオン宇宙船の大気圏再突入から着水までを、宇宙船からから撮影したものです。 アルテミス1ではスキップエントリーという方法で帰還しました。大気圏に再突入した後でいったん宇宙空間へ戻り、その後また再突入するという方法です。水面に石を投げた時のいわゆる「水切り」に似ています。 アルテミス2では、大気圏に一度突入した後の「スキップ」を抑えて地上へと降りてきます。 詳しくは記事をご覧ください： astropics.bookbright.co.jp/a… Credit: NASA

"I couldn't look at myself in the mirror", says climate scientist @simondonner, who is one of the two climate advisors that quit the federal government's Net-Zero Advisory Body. Full interview: youtu.be/x1JYcA9srH4?si=xnXh…

Personal update -- I resigned from my role at Co-Chair of Canada's Net-Zero Advisory Body. The job had been a true honour and privilege, one of the highlights of my professional life. If you're interested in more of an explanation, please see my Linked-In page.

The MOU with Alberta is deeply disappointing. It sacrifices climate policies, puts too many eggs in the industrial pricing basket, proposes a pipeline deal that would increase emissions, and would have Canada double-down on fossil fuels while the world moves towards clean energy.

It is also giving me deja vu. I'm working on a more detailed analysis of the MOU, and was reminded of writing this for a similar analysis nine years ago:

UN climate summits are a strange hybrid of diplomatic negotiations and a sprawling climate change bazaar. You can learn the state of climate action from watching the negotiations and the concurrent panels and side events. Here are five themes that emerged frequently at #COP30:

4) US left behind: The US absence was quickly normalized. Whether out of frustration or conviction, delegates spoke of declining US relevance. As an African govt rep said: “Americans should realize the world is moving on from them... other nations are this as an opportunity.”

5) Global divide: An emerging schism between countries clinging to a colonial + extractive past and those moving to the future. It goes beyond the fossil fuel vs clean energy divide to whether adaptation relies on top-down initiatives vs. local + Indigenous efforts and knowledge.

As Canada scrambles to diversify its exports, fossil fuels are an increasingly risky bet, not least with taxpayers’ money. And we should not kid ourselves: it is also a bet on global failure to address #climatechange, says @simondonner @ubcires @ubcgeog nationalobserver.com/2025/11…

Canada’s proposed oil and gas expansion is a risky bet – for the planet and our economy

Updated pledges before this year’s COP30 meeting in Brazil fell well short of what’s needed to achieve net-zero emissions by 2050.

The Pacific Islands pavillion at #COP30 just had to close due to flooding. Seriously...

As we near the end of the first week of #COP30, this passage from the current version of the global stocktake text (on progress towards the Paris Agreement goals) captures state of the negotiations:

IPCC chair Jim Skea called the IPCC the El Niño of the climate policy world, in that its reports appear around every seven years. Nice line that wouldn't land in most settings. Granted, the key difference between the two is that geopolitics can't delay or alter El Niños

For years, people argued that there's no point in taking climate action without China. I was just at a #COP30 event where Chinese govt officials and renewable industry reps outlined the fast-paced energy transition and long-term carbon neutrality plan. The story has flipped.

For all of the justified critiques of the expanding and often frustrating UN climate summits, there is something beautiful about watching the melange of people in the hallways, with folks in all manner of traditional clothing walking next to western technocrats in business suits.

There's no official American delegation to COP30. There will still be Americans in attendance, as observers from non-govt organizations, universities, etc, but no delegates participating in the actual negotiations. carbonbrief.org/analysis-whi…
