A cooler sun?

London, England

 Astronomers have detected that the solar sunspot cycle has ground to a halt. With an expected return of activity 12 months ago, the sun’s internal circulation is still quiescent. Now, it is believed, we may have to wait until 2009 for the sun to gear up its systems for a return to more or less normal. And, importantly, this may cool the Earth.
Meanwhile, George Monbiot writing in the UK’s Guardian argues that ifwe are to avoid runaway global warming we will require 100% cuts in emissions by 2050.
Humanity has to face up to this sort of unpredictability right now. On the one hand we face catastrophe through overheating; on the other, we may be spared global warming for a while.
Are we capable of responsible change? Do we care?
Or will the human race simply consume itself into oblivion?
