Alpha informs Wayfarer that:
Solar radiation will increase;
the warmed Earth will have more atmospheric water vapor, a powerful greenhouse gas;
hard sunlight will split rising water molecules into hydrogen, which will escape into space, and oxygen, which will bind to surface materials;
fires and rocks exposed to erosion will release large quantities of carbon dioxide, a second greenhouse gas;
oceans will boil;
but long before that, within a hundred thousand years, life will have become extinct.
Should intelligence intervene?

Kaor, Paul!
Of course intelligence should intervene, preferably human and under human control, direction, and supervision. I recall suggestions about a "shield" being built to deflect much of this heat from Earth.
Alternately, instead of trying to save Earth, humans might decide to relocate to Mars (terraforming it, if that had not been done). Mars might well have been far enough away from Sol that the extra heat coming from the Sun would be BENEFICIAL.
Ad astra! Sean
