Blimey! Australia's legendary Dr Karl Kruszelnicki talks exclusively to Ol and Dave.

Is climate change real? Is it going to be bad? What should we do about it? And whose fault is it that we're not doing enough?

All this and some scientific explanations of how solar power works, and why marital relations can make you temporarily deaf.
