I don't know what all the fuss is about really. It is only going to be another 3.5 billion years before the Sun moves to the next phase of it's natural cycle and becomes a Red Giant. It will be 250 times it's current size and will eat up the inner planets. The Earth may survive but the seas will boil off and life will be extinguished. No amount of wind farms or carbon offsetting will make the slightest difference! We need spaceships!!
