Protest kicks the COP30 facility on Friday morning. It is being treated very respectfully, as far as I can tell.

This article from @bryancurtis.bsky.social is bang on. Institutions bowing to Trump doesn't work. It only stokes a positive feedback loop based largely on a false perception of strength and inevitability.

Flow of the Guadalupe River outside Kerrville, Texas. What gets me is thinking about what all those people experienced, the shock and panic as the river quickly rose. We can be mad about the lack of warning systems, about a million other decisions that weren't made. We can also just be sad.

Climate action is not just about future generations. The choices we make today will help determine the climate impacts that people alive today, people in our lives, will experience over the rest of the century (and beyond).

We talk a lot about the level of climate warming, have we passed a given threshold, and less about the rate. The rate is the core problem: we are changing climate faster than society or the environment can adapt. If it took 10,000 years to warm by 2 C, this would be a different conversation.

There may be nothing more thrilling than finding a data logger buried in the ocean for two years. We rely on hand-drawn underwater maps b/c we can't leave obvious markings. This is i-Kiribati colleague Aranteiti Tekiau revealing our hidden treasure, recovered on a dive in Abaiang Atoll last month.

Little reminder during a tough news week that the planet is still awesome... here are some dolphins jumping along side our boat during field surveys in Kiribati last month.

The initial objective was to use available experimental data to test for hormesis (low doses of heat stress are beneficial, but high dose are harmful). It proved hard to evaluate, because lab "heatwaves" were too hot and too short, more akin to heat shock than real heatwaves. (2/2)

Environment and Climate Change Canada released its summer forecast today, predicting warmer than normal conditions across most of the country. Notably, "normal" is considered 1991-2020, which for Canada is ~1-2 C warmer than the pre-industrial climate.

We need to plan for the future, not the past. I talked to @theenergymix.com about the risks of a "grand bargain" of pipelines for carbon capture, and the problem with some of the energy conversation in Canada.

The Trump admin is cancelling a series of important climate research programs wasn't shortsighted enough... and the rationale is essentially that it's safer to put your hands over your ears and yell "I can't hear you". www.commerce.gov/news/press-r...

Calling for the west to secede from Canada if your party loses an election, at the same time that US President Trump announces worldwide tariffs that experts are calling batshit crazy... is a choice.

This is the energy issue facing Canada. We may need to double electricity generation in the next few decades, which means investment, process reform, better consultations with Indigenous communities, and getting the provinces to work together. We need to talk about this, not just pipelines and LNG.

Yeah, it is quite possible that the US President's interest in Greenland comes partly from going to school at a time that maps had flat projections (or from looking at Google Maps or other online maps with flat projections, which make Greenland look much larger than it really is.

It tracks my anecdotal experience: most people I know don't want to travel south of the border either because of anger about the tariffs, fear of being detained, or both. Trump is wrecking a friendly relationship.
