Global Cooling

[oil pan 4]

When the next vei 7 pops we won't have the luxury of worrying about the man made global warming fantasy.

1) would depend on where one were at the time.
2) everyone within a thousand miles would be dead.
3) Skies could be darkened for two years,
4) Mount Tambora's 1815 eruption cooled the whole planet 2-F.
5) all depends on magnitude of eruption.

what would yellowstones eruption do to the planet? at least we can stop an astroid. cant stop yellowstone...

Who is the 'we' that could stop an asteroid? We can track Sun-orbiting objects, but interstellar objects come out of the North or South and they can potentially exceed orbital velocities.

But, you asked:

It turns out volcanoes are good for you. Except the Long Valley Caldera?

Long Valley Caldera - Wikipedia
Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth Mountain. The valley is one of the Earth's largest calderas, measuring about 20 mi (32 km) long (east-west), 11 mi (18 km) wide (north-south), and up to 3,000 ft (910 m) deep.

Presently, NASA's plan is send a spacecraft out to any Earth-intercept asteroid and give it enough of a nudged force vector, to deflect its trajectory away from us.
NASA's already successfully landed spacecraft on asteroids. A small, impulse rocket motor, operating over a long-enough duration, could do the job.
Not 'sexy', but it'd get it done.

I know a recent European probe to an asteroid didn't go so well.

Bennu? That was more of a boop than a landing.

'Sexy' is when you park it in a Lunar orbit and proceed to strip-mine it.

That might cost the entire global GNP. You'd want to know that it was worth it, ahead of time.

Spring has brought remarkably extreme heat to India and Pakistan this year. Unusually extensive heatwaves have followed one after another since March and are continuing well into May. The situation presents a conundrum for rapid studies of the role of climate change in this event, as we can't yet put an end date on it. ... Record-breaking heatwaves often coincide with drought, as the dry ground heats up even more without the cooling effect of evaporation. However, the lower humidity has reduced the heat's threat to human health, though at least 90 deaths have been reported so far, and that number is expected to rise.

One comment points out that the record high was set back in 2017. Another suggest people will do better than crops.

This is insightful to Slashdot's current state:

Slashdot used to be a titan of the internet, ranked something like the 14th most visited site. Now it's a fading echo.

I believe (IIRC) this started around 2015 when the (relatively) new ownership stated explicitly that their goal was to use slashdot to promote a societal good (of their choice), rather than the goal of keeping it popular.

I still think their moderation system is the best, if not immune to bots.

I plan to maximize flourishing during changing climate, because I'm maximally equipped to respond to events in my life, and everything else I have minimal control over.

Authoritarians are out of control and need outside influence to regulate their environment (outdoor thermostat for example) and Liberals leverage control over the things they can, leaving as little to chance as possible.

4) Volcanism is not periodic in nature. There are no 'cycles' associated with it that I've experienced in the literature. It is associated with tidal forces, plate tectonics, lithospheric isostatic rebound as ice sheets melt, and seismic activity.
5) The Milankovich 'wobble' has a periodicity of 23,000-years.
6) The 'tilt' cycle is 41,000-years.
7) The 'ellipticity' cycle is 96,000-years.
8) The solar sunspot cycle is eleven years, with a delta-irradiance of 0.50%.

8 has been retraced in nature magazine. It's debunked junk science.
