Astronomer royal calls for 'Plan B' to prevent runaway climate change

[oNobodyo]

62. I did...

and it's gone beyond speculation and to the point where the infrastructure is already being developed...in other words "it's already being done"

I do remember what the thread is about...

Geoengineering or Terraforming this planet to stop runaway warming with secondary emphasis on the need for multiple plans to adapt and ameliorate it...

Runaway warming I would remind you is a global extinction scenario for nearly every specie on the planet save for certain extremophiles and having all of ones eggs in the same basket is rarely a good idea and never when those eggs constitute the only known life in the entire universe.

"Give us the link to NASA saying they could build a world-powering solar energy system for $500 billion."

And yet again you attempt to set up a strawman argument....Please stop, it's really not very polite.

At what point was the claim made that you could or had to power the entire planet from space based power stations for $500 billion?

I've quite explicitely said that the power needs only be used THERE instead of here to be of positive effect. With space based power you don't have to lift power sources for every satellite which is the majority of their mass now.
