I've been looking at some recent studies on the Earth's natural climate cycles, like the Milankovitch cycles, and how they interact with human activity. While orbital forcing has driven long-term cooling trends over the past few thousand years—like the gradual decrease in summer insolation in the Northern Hemisphere—the timing of these cycles doesn't align with the recent rapid warming we've seen. In fact, the last few decades of warming are happening at a rate that's far beyond what natural cycles alone could explain. This suggests that while long-term cooling trends have occurred, the current warming is largely driven by human factors like CO2 emissions.
