Launched some ladybugs 🐞 onto the aphid infested oak tree. Go get those aphids!
Dinner salad tonight includes white currants and two varieties of blueberries from my #Seattle garden. Yum.
"The [US] administration is corrupt, incompetent and, most important, hostile to the norms and values that animated the founding fathers. The Declaration of Independence proclaimed liberation from tyrants. Donald Trump wants to be one."
Sooooo…unsure whether this is more or less concerning than the stabbing earlier this week.
By @davidfickling.bsky.social "If you combine the value of public investment and public subsidies, about 59% of all money spent on the fossil fuel system came from taxpayers in 2015. By 2025, that had climbed to 68% and spiked as high as 78% in 2022." Good chart. www.bloomberg.com/opinion/arti...
Here is the source, which somehow I have never read. I also contains this excellent and timeless bit, which applies to our current situation as much as when it was written. The Age of Reason, Part III, Thomas Paine, (1794-1796) standardebooks.org/ebooks/thoma...
Wondering where to find the latest on how the climate is changing? Have a look at the Climate Dashboard at @climate.us . Talk about it with your neighbors. Build community. And maybe move a few votes.
From my Lopez Island sojourn, the inside surface of a clam shell colonized by baby barnacles. I wonder how long it will stay in the orientation and stay wet at low tide?
Urban wildflower patch coming along nicely. Two new ones I don’t recall seeing previously.
Yeah but will it actually affect voting in mild or deep red states? "Opposing changes to longstanding vaccine policies is the correct political posture in every state surveyed, across virtually every Republican subgroup measured." Red states and vaccine mandates www.cidrap.umn.edu/childhood-va...
Evening sky in the San Juan Archipelago. High white puffy clouds lit from underneath by a setting sun, between tall fir and cedar trees in the foreground and blue sky above.
Heard a claim yesterday that energy price increases, which fall hardest on lower income consumers, are primarily due to carbon taxes. No. By far the largest cause of increases in costs for all consumers is the increase in the cost of fossil fuels. 🔌💡 ember-energy.org/data/europea...
I updated our chart on China's PV installation trends and implications thereof. China is indeed slowing. Ex-China has been steady at about 21% for 5 years. China could precipitously slow to the ex-China mean (which I doubt will happen), and we would still see many years of >20% global growth. 🔌💡
The origin of the Laffable Curve below, for those who do not know, was a cartoon on a napkin. There was no data to support it then. And there is still no data to support the idea that lowering taxes generates sufficient revenue to pay for the cuts. Still just a cartoon.
Fairly sedate dodging tonight on Lake Union in #Seattle. #duckdodge On nights like this when there is very little wind, the dodging is reduced to lazy waving as boats drift past one another.
From today's FT Energy Source newsletter: "there is a real danger that price increases and supply disruption will destroy oil demand...in China, oil demand has fallen as much as 9%" 🔌💡 Oil industry faces ‘gruesome’ demand shock from Iran crisis ep.ft.com/permalink/em...
“The only source of generation or technology that can facilitate that increase in demand [from data centers] is gas generation,” said an analyst. 🙄 Gas is only a small fraction of the interconnection queue, even in ERCOT. Renewables are growing far faster. 🔌💡 www.ft.com/content/4af8...
Ooops. Forgot to update one of the subplot titles. And now with alt text.
With the BNEF NEO 2026 now out, I pulled the annual PV installation data and ran our scenario model. The globe is still on track for 75-100TW in 2060. But BNEF has installation slowing down a lot soon. It is unclear why installation of the lowest cost energy source would slow so precipitously. 🔌💡
