I know you're joking but it wouldn't surprise me. A few years ago I would have said: no, I expect they'll be dead before that happens. Unless life-extension kicks in early. But who knows? Technology is racing ahead in certain ways (AI, etc.)... The very wealthy and their chosen will colonise other worlds. Homo sapiens? Homo insipiens–unreasonable man! To spoil paradise, only to give it away for some dull, dirty and cold rock somewhere far away... I hope Elon & Jeff suffer from space sickness all the way there and back again.  Meanwhile I keep on increasing the earth's albedo. Up to now I've enlarged it by 7m², reducing the earth's surplus energy by about 2.3 kW per year. If I estimated it right, now there are only about 535,000 km² left to do.  Sad but true. And good on you for what you've chosen to do. |

Elon & Jeff will be such flats when the next one rushes in. |

I'm anticipating the 'cure' for faster than light space travel, to where 2nd and 3rd Earths may be found.  |

Humans will be off-world by then. (Some of them anyway.) ♫ “Mars ain’t the kind of place to raise your kids…in fact it’s cold as hell…”♪ (Rocketman, by Elton John)♫ “This town ain’t big enough for the both of us…and it ain’t me who’s gonna leave!…”♪ (by Sparks) |

I believe that the advancing (almost exponential) rate of technological/AI development will soon bring about possibilities that were heretofore just dreams.
Science fiction is already becoming science fact.

Did I just use 'heretofore' in a sentence?
Wow.
That's probably not good.

Science fiction is already becoming science fact. 'It always seems impossible until it's done.' O.k., then: first things first. 1. Fight global warming. 2. Secure peace of a growing population. ... 8,000,000,001. Spend $ 200,000,000,000,000 to put some clown on another planet, light years from here. |

And there I was poised to quote a line from Star Trek... Oh well.  |

Freezing rivers would be a sign of global coldness not warming Haardrada??!!
Niagara partially froze over in 2022, although last fully frozen falls on record was 1848, I believe.
I think global warming of seas is quite well documented. Yes it might have happened previously without humankind input but us humans are certainly lending a big hand to process in last 250 years.

Great idea except for the mirrors. If, as an ex navigator, I am using VFR peering down on a hot sunny day into a blanket of mirrors might have a detrimental effect on my vision I fear!
Great for glider pilots mind you, with all those thermals,

Great for glider pilots mind you, with all those thermals, Thank goodness there are even some milder technical solutions... |

And another one: 3m offers a kind of tape or foil that uses passive radiative cooling. More details. |

I found a very interesting article about reflective surfaces. It seems that these will play an important part in near future. |
