Here are the trends in summer length for the mid-latitudes globally, as well as for 10 cities with consistent long-term local observational records. Sydney, Minneapolis and Toronto had the steepest trends. iopscience.iop.org/article/10.1...
One of the locations that jumped out in @climate-ted.bsky.social's analysis of changing summers was Syndey, Australia, where local weather data shows that the length of summer weather season has almost doubled over the past sixty years. www.theguardian.com/environment/...
The 'tell' that the old "let's spend money on alleviating poverty not climate change" argument is BS? The people who make that argument oppose international aid and money spent alleviating poverty.

I'll be giving the keynote at the Sunshine Coast Climate Faire in next Friday night. Take the ferry over to beautiful Gibsons if you want to hear about the latest on climate action, the importance of courage, and how to find your way home if lost at sea.

(Will I at some point make a complete out-of-context comment about my frustration with the constant restructuring of coral taxonomy, especially disbanding the Faviidae family and messing up our longstanding field survey protocol? Quite likely)
I'm flattered to be appointed to this new council informing guidelines for sustainable investments.
Can setting such guidelines help cut emissions? Yes!
Do I think about classifying organisms not investments when I see the word taxonomy? Also yes!

The magnitude of these forecasts continues to surprise me. Strong El Nino events are quite uncommon, happening only once every 15 years or so, and often on the heels of a moderate event like the 2023-24 El Nino.
Do you have the sense that summers feel different than when you were younger? That they start quickly, and remain intense until the fall? You’re not wrong. (thread)
You aren't imagining things... summer is starting earlier and lasting longer. Here's @climate-ted.bsky.social describing our new research on how summer is changing around the world.

🍁 HEY CANADIANS I will be on your gorgeous west coast next week to 1) be jealous of your political leadership 2) talk about Heated Rivalry 3) speak at UBC. Please come say hi!
Do you feel like summer is getting longer, hotter, worse? Spring and fall are shorter and faster?
Science agrees.
This is another example of #climatechange.

New research led by @climate-ted.bsky.social finds that summers are getting longer and starting faster, on land, on the coasts and at sea.

Join us at UBC on Tuesday April 14 for the annual Climate Solutions Summit, where researchers will talk about new cutting-edge work on subjects ranging from footprint of cloud computing to bringing climate justice into teacher education.

Next Wednesday, @drkatemarvel.bsky.social will be at UBC to talk about about her beautiful book Human Nature. Join us if you are in the Vancouver region, there are still a few tickets available.

Artemis 2 astronauts see Earth in the rear-view mirror | Space photo of the day for April 3, 2026 "That's us, together, watching as our astronauts make their journey to the moon."
This is a policy decision from the 1990s. Might as well release it on a floppy disk or VHS tape.

I had a great visit to Univ. of British Columbia a few weeks ago. Thanks to @simondonner.bsky.social for inviting me and hosting the visit.
Here is a copy of my first talk, which was a public lecture so less technical than a normal seminar.

Honestly, I think most people just look at the graph, and how unusual recent temperatures are comparing to the past 70k years, and don't worry too much about the wording of the labels.
I'm just explaining why it says historical period. Perhaps it was just trying to use words and terms that more people recognize. Common Era is used in the literature, but I don't think they average person knows what it refers to.
Nice figure. As usual, the IPCC figure is dense and more difficult to follow!
True, it is vague, and I think that is defined more based on the density of the proxy temperature record data.
" Once you've got your solar panel there's no cost for the sun."
"With a stroke," says @kingsmillbond.bsky.social, "this war has dramatically increased the power and the influence of those who want to go down the solar route."
Here's why countries are glad they invested in solar, batteries+ EVs ⬇️
The figure is from the cross-chapter box on paleoclimate featured in Chapter 1 of the Working Group II report from the Sixth Assessment, available here: www.ipcc.ch/report/ar6/w... (and found on page 155 of the pdf)
This figure from the Intergovernmental Panel on Climate Change's last report puts climate change in perspective. We are changing the climate faster than any point in modern human experience, such that the planet is now warmer than at any time in the history of human civilization.
Silently hoping that @doctorow.pluralistic.net will apply the enshitification theory to WorkDay, the omnipresent finance and HR management tool that every user wants to launch into the sun.
For sure, I hear you. Sometimes that's all we can do, right? There are lots of reasons to cry right now. Just make sure you get up afterwards.
I hear you, but don't share the existential dread. People today, especially my generation and that after me, have the opportunity to influence the future of the planet in a way that has never happened before in history. I find that inspiring... it's why I talk so much www.youtube.com/watch?v=CZ_M...
At the end of an excellent NY Times column about solidarity in Minneapolis is this passage, which speaks to why I dislike calling climate change an environmental issue. It is dynamically more like a global systemic issue than it is other environmental issues.

The meandering narrowness of atmospheric rivers makes it seem personal, like the atmosphere is going out of its way to target your neighbourhood.
