No, the issue at hand is why we aren’t cooling off, not why we haven’t reached a nadir.
But the temperature graphs I’ve seen don’t look anything like a 24,000-year cycle, either.
Why aren't we cooling off? Maybe because we are just barely past a high in the sunspot cycle.
And, it's the wrong question anyway. Why was the global warming rate higher before the 1950's than it was after? The supposed C02 increase came in the later period. Global warming should be zooming up now that the economies of China and India are zooming up, but it isn't.
In regard to the man-made GW theory, the question isn't why aren't we cooling, but why aren't we warming in the last decade. The sun-made GW theory is clear that the Sun is at a peak, warming should be slowing, and cooling to happen some years ahead.
