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-induced factors. While the long-term cooling trend over the past few thousand years is debated, the key nuance is that this cooling was gradual and occurred during a period of overall relative stability. The recent rapid warming, however, is happening at a pace that's unprecedented in the instrumental record and is largely driven by human activities. So while the long-term trend might be "mostly true" in a broad sense, the context of recent acceleration is what makes the current situation so concerning.
