We should make some and send it there.......................

Ain’t been making more protons since ~3min after big bang

if incoming sunlight changes too fast, you could get a Snowball Earth,” says lead author Constantin Arnscheidt, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “What this highlights is the notion that there’s so much more...that we don’t know
about our own sun...

“evidence suggests that the consecutive global ice ages set the stage for the subsequent explosion of complex, multicellular life on Earth”

in which case, these quickie ice ages could have been part of deliberate terraforming and the next phase in life creation ...

Thanks Red Badger, nice three-lister topic!

Researchers have been keen on finding exoplanets within the habitable zone... The new study suggests that these planets, like Earth, could also ice over temporarily if their climate changes abruptly. Even if they lie within a habitable zone, Earth-like planets may be more susceptible to global ice ages than previously thought.

like Planet Smoothy? 😋

Mmmm, jamocha...

[gleeaikin]

I have been wondering what our sunspots have been up to most recently? A while back it was suggested we are leaving a very quiet sun period. Also SC, thanks for links.

You’re welcome.

I’m not a climate scientist but from what I have researched

I kind of doubt we will see an active sun again in our lifetime

Don’t take my word for it but I think everyone should plan to

move closer to the equator in the next 50 or so years.

6000 ppm Co2 was a thing at a prior time. That’s about fifteen times the current value. The Co2 thermal augmentation effect is tied to a logarithmic progression, so most of the heating happens with low percentage values of the gas in the mix. Water vapor is the real driver of heat retention.

Ocean circulation was different such that more warm surface flows similar to the Gulf Stream, carried oceanic warmth to the polar regions. The formation of the Isthmus of Panama made a large contribution to cooling.

Statite mirrors will be cheaper.

Things like heavily doping the atmosphere with sulphur compound aerosols?
