Earth has emerged from multiple recurring ice-age cycles that have followed the exact same pattern for a million years—warming roughly 5–6°C every 100,000 years. These warm interglacials did not once trigger a global environmental crisis. Indeed, civilisation itself arose within the 11,700 years of today's warm Holocene interglacial. Reducing a planetary-scale biosphere to a sudden climate crisis within a few decades ignores the entire geological record. Earth’s living biosphere is dynamic and resilient. This is demonstrated in real time as plants and farm production increase, supported by marginal rises in CO₂ levels at around 1 to 3 ppm a year. The moderate warmth and available carbon are driving a visible expansion of the green leaf plants and cereal crops—as recorded by NASA satellites. Atmospheric CO₂ is not a threat to on-going life on Earth. The world warms or cools almost entirely from natural cycles and nature's variability. CO₂ is the building block for life—the essential driver of photosynthesis and primary plant productivity on land and in the oceans. There is no evidence CO₂ variations trigger ice age glaciations or drive interglacial recoveries. These are by and large a the predictable consequences of the Milankovitch orbital cycles, followed by ice-sheet retreat, falling surface albedo, and subsequent shifts in ocean circulation. The paleoclimate record shows that CO₂ 'follows' the rising temperatures on multi-millennial scales. The net-zero agenda rests on the claim that CO₂ 'leads' temperatures on decades long time scales. Yet the Antarctic ice-core record (EPICA Dome C, Vostok) is specific: temperatures consistently rise several hundred to a thousand years before CO₂ increases. This lead–lag relationship has been settled science for over two decades (Caillon, 2003; Pedro, 2012; Parrenin, 2013). Only after the oceans—especially the Southern Ocean—have warmed for centuries does dissolved CO₂ outgas from the deep, slowly raising atmospheric levels.
