Default Want to know the REAL future of climate? Ask an astronomer

One thing is certain, though: Climate models have NOT taken these phenomena

loudly proclaimed that the science is settled.


The standard 11-year sunspot cycle is known, and thus can be predicted, but not
unexpected changes in solar activity.

But even if climate models ignored solar activity entirely, all that would mean
is that the effects of an increased carbon dioxide concentration in the
atmosphere might be hastened or delayed.

The greenhouse effect itself isn't in doubt, only the details are. Using doubt
about the details as an excuse to avoid taking the action needed to prevent a
catastrophe is not responsible.
