Dinner Bell
We've been adopted by one of the neighborhood cats, and I've been trying to get her to come when I make a non-verbal cat-call (if there is a word for that sound, I don't know it). She must not have been nearby because I didn't hear her footfalls in the leaves in the neighbor's yard, or even a meow to let me know she was on the way. It was last call, though, so I set out some food in the hope she would get it before the raccoons found it.
No such luck.

Saving Mineral King
Exploited by miners in the 19th Century, the awe-inspiring valleys of Mineral King came very close to becoming Disney-fied -- literally. Walt Disney wanted to build a ski resort up there. It was a very popular idea at the time, but the Sierra Club came out against it and won a victory in the US Supreme Court that was important not just for preserving the valley, but also for winning the right of citizens to sue the federal government to protect the common good.
"Just as important as the protection of a lovely valley was the precedent set through the lawsuit. The case confirmed the right of citizens to seek the help of the federal judiciary when any public resource -- land, air, water, wildlife -- came under threat. It established that Americans don't have to have an economic interest to have the legal right to get involved in protecting special places or stopping pollution; we all have an interest in keeping open space open, or in breathing clean air." --Tom Turner in High Country News
Back around 1990 I drove across the country on my way to spend the summer on an island called Manhattan. On the way I stopped in Bozeman, Montana, and got to talking with someone who said I really shouldn't miss seeing Glacier National Park. Unfortunately, I was too impecunious to be able to make the side trip.
There's nothing I could have done, but I do regret having to pass it up. I suspect now that whatever I could have seen back then is already considerably less amazing. Throw in the trophic cascades associated with the ecological benefits of the glaciers, and the bummer of losing them becomes even worse.
“We have just ten years to avert a major catastrophe that could send our entire planet into a tailspin involving extreme weather, floods, droughts, epidemics and killer heat waves beyond anything we have ever experienced.” – Al Gore in An Inconvenient Truth, 2006
Ten years after Gore's warning, atmospheric CO2 cracked 400 ppm. Unfortunately, it kinda seems like we won’t know with absolutely certainty whether we’re just in a wobble of turbulence, or an actual tailspin, until it’s too late to pull out of it.
Of course, for people who've already suffered losses on those five checkpoints, it already is too late. For the rest of us, we'll have a good clue that the end is near when insurance companies stop selling coverage for the five checkpoints.

Beach Weather
The verdict is in, and it looks like the ocean goddess is going to show her cooler side this year. Strong equatorial winds are pushing sun-kissed surface waters west, bringing cold water up from the deeps and sending it farther north than usual. One result of the colder ocean waters will be less rain for California.

Complementary Color
We lucked out today, as an area of low pressure moved in (windy.com). All that NorCal and Oregonian smoke that was streaming down the coast yesterday is now going the other way, and out to sea.

Amber Alert
My wife was trying to use her phone camera to capture the eerie amber light around sunrise this morning, but it wouldn't work. The software refused to believe it really looked that strange.
I woke up from a poor night's sleep, having spent too much time at around 1 a.m. thinking about how climate scientists have been sounding the alarm for decades while we twiddle our collective thumbs. The group called 350.org was named for the CO2 target of 350 ppm, a greenhouse gas concentration that we passed in 1990. We surpassed 400 ppm in 2016 and are at 412 ppm now. We are simultaneously making history and ending it.
Multi-cam View
Last year marked the first time in several million years that atmospheric concentrations of CO2 passed 400 parts per million. By looking at what Earth’s climate was like in previous eras of high CO2 levels, scientists are getting a sobering picture of where we are headed.
[UPDATE: Earth Day, 4/22/2024, atmospheric CO2 at 426ppm.]
