A breezy day over the North Atlantic.
I noticed whitecaps during a break in the cloud cover, and snapped this photo with the Adobe Indigo app on an iPhone 16 pro (at 10x zoom -- 2x digital * 5x optical [f2.8 128mm 35 mm equiv, which Apple lists as having a 20º fov] so this image is 10º wide). The plane was at 39 kft. I count approx 40 waves across the fov, which makes the wavelength L≈50 m. Wind velocity is √(g*L/2pi)≈9 m/s, or about 20 mph. Excellent sailing weather.

Almost all of our energy sources here on earth are solar, in the end.
- Solar panels, obviously.
- Wind is powered by the sun.
- Water is lifted up in the air by the sun before it rains.
- Coal and gas are ancient solar energy gathered by plants.
- Geothermal energy is, in part, caused by the moon or left over from the formation of the solar system. Which was caused by the sun.
What I find much more amazing is that there are some energy sources that are from the *previous* sun, created when it exploded:
- Nuclear fission energy is created from large atoms created at that time. This includes a portion of geothermal energy.
- Insofar as there are any of them left, some chemicals we can still burn/react were created then.
But there is one energy source that was not created by any sun:
- Nuclear fusion of hydrogen into helium. The hydrogen was created by the big bang!
(sometimes we forget that old puzzles have been solved)
Climate Science denial is a very Anglo-Saxon phenomenon[1]. It has has known explanations that connect it to other denials and science denial in general [2][3]. There was a network of individuals and organizations behind it.
In short:
It started in the 1950s. Anti-communism and associating government regulation with communism led to network of well funded denial. Denial of tobacco smoking causing cancer, acid rain, DDT, the hole in the ozone layer, climate change. Same organizations, lobby groups, and scientists.
It took long time to take a hold. Environmentalism remained bipartisan for a long time, Richard Nixon created the Environmental Protection Agency, signed Clean Air Act extension, Clean Water Act, the Endangered Species Act, and the National Environmental Policy Act.
They triumphed under Ronald Reagan.

@maxpool - America has become a sceptic tank. I predict that the next trend, now that weather disasters are rising unmistakably, will be for climate change deniers to blame them on evil conspirators - Democrats, of course.

@maxpool - Now the climate change deniers have latched onto the fact that a company called Rainmaker was doing cloud seeding in Pleasanton, Texas on July 2nd, about 150 miles southeast of the floods in Kerr County two days later.
