Sun's Fickle Heart May Leave Us Cold

Attila is apparently a common name in Hungary, since the original Attila used the country for his base camp. I'm a little more skeptical of the "Grandpierre" part.

[Alas Babylon!]

Atilla Grandpierre. That's Atilla the big Peter.

more oxygen, and consuming more CO2.

There was a mini-Ice Age that lasted from around 1400 until the mid-19th century.

Higher temps would mean more plant life activity producing more carbon dioxide.

And also more chlorophyl -- which ultimately is the food of all living organisms here on earth. (I.e., animals eat plants, humans eat plants and animals....)

The guy"s name is Grandpierre. Big Peter?

Attila Grandpierre..... we could call him "Attila the Hung."

These instabilities would induce localised oscillations in temperature.

And these in turn serve as causes for other forms of complex activity on the Sun which, since we live in Sol's close-by neighborhood, have very direct effects here on Earth. As Attila has told me, the Sun "is not 'a hot ball of gas,' nor is it simply a fusion reactor (machine)." Rather, despite the fact that it is not a "carbon-based lifeform," the Sun gives evidence of behaving in ways that we associate only with living systems.

I'm tickled to see my friend, an astrophysicist who specializes on the Sun, cited here! Thank you so very much for the ping, marron!

Indeed!!! Thank you both so very much!

Gee, I never in a million years thought that all this heating and cooling could possibly be caused by the sun. /sarc

Actually it is less now than 325,000 y/a and about the same as 125,000 years ago. It seem the CO2 levels and temperature go up and down on a pretty reliable schedule. About every 125,000 years both go up. We would seem to be at about the high point of that 125,000 peak and should be dropping off soon.

This graph brings up a question. Do the temps go up because of CO2 or do CO2 levels go up as temps rise?

[redangus]

Wrong Kemosabi. You are right that higher temps might mean more plant growth. However, plants sequester CO2. They take it out of the air and through photosynthesis combine the carbon with hydrogen and oxygen to produce starch which is stored in the plant as an energy source. As by-products they release O2 and water into the atmosphere as by-products. This would actually lower CO2 in the atmosphere and increase the level O2.
