Seems unreasonable to expect people to work together during a civilization-ending catastrophe.

This actually sound very reasonable. About the only time people can agree is when there's a danger. Nothing unites people more than a common enemy (or, in this case, a phenomena). But I think GPs point was that if it starts getting colder we go back to carelessly pumping CO2 into atmosphere, but for now we should go with the mainstream science and keep on reducing that.

Haha, i thought the same thing when Covid started getting serious. Boy was I wrong.

Is it related to the 11 year sunspot cycle or just a coincidence?

For layman explanation it was just discussed it on StarTalk just a few days ago https://www.youtube.com/watch?v=lty_55JbkmE

The point of the show is to bring science to common people. Many of the startalk episodes he brings on pop culture icons or sports commentators. They dumb down the content substantially, but my mom and my grandma really liked those types of episodes so it must work.

Reality is more mad max style free for all. Guy with the biggest muscles and guns wins.

> To geologists, an ice age is defined by the presence of large amounts of land-based ice. That's pedantic. > Physics, thermodynamics, informs us that the glaciers aren't coming back while the insulation in the atmosphere is high and still increasing. Meh. The running hypothesis on the "other side" is that we're going to have a pole shift and grand solar minimum at the same time. Now, as you can see, I haven't really…

Climate is always changing. Earth itself and the sun caused many extreme conditions on earth. Humans can do it now as well. But nothing compared to natural causes. Nevertheless we humans should have full control of our atmosphere at one point.

Can we get a vote-to-ban button for posters like this? It’s getting bad lately and clearly this has become too big a job for Dang.

Alongside a button that votes to ban people who clicked it? Or will flags/bans remain risk-free?

Interestingly this happens every 11 years and also their is a longer cycle called the Hale cycle which is double the length at 22 years. It flips from a mostly dipole where the poles match the orientation of earth to a reverse and much more irregular magenetic orientation. I didn't see anything about how this really affects Earth directly other than what I knew previously about sun spots make Coronal Mass Ejections s…

My understanding is that the Hale cycle is just a complete "360° flip" of 2 "180° flips". I.e. the 11 year cycle is essentially going from "mostly dipole" (but say with north magnetic direction going one way) to irregular and then back to mostly dipole, but this time with magnetic north pointing in the opposite direction. The next 11 year cycle gets magnetic north pointing back "up" again.

The food pyramid is misunderstood 'those scientists' were from Sweden responding to protests over the increasing costs of food due to famine. When looked at from the lens of maximizing calories per dollar, it makes a lot more sense.

it could have been divine revelation. what matters is that it is used to this day for policy.

In what way do you think the food pyramid is used today for policy? It's been known to be incorrect and not used for quite a while ...

If there is a correlation, it’s definitely interesting, the same way all science is interesting.

No, correlation alone is not interesting at all. If you were right we should be studying how the reduction in piracy over the last few centuries is strongly correlated with the increase in global warming. Pure nonsense.

Correlation is always interesting, and until you study it, you can’t even prove that it’s “correlation alone” and nothing else. Yes correlation is not always causation. But, correlation often opens up an entry point for new research. Most of modern medicine is heavily dependent on correlation.
