The climate alarmists rarely mention a fundamental geographical fact: Earth is in the Quaternary Ice Age.
We are simply living through a warm interglacial period—known as the Holocene. Over the last 250 years, global temperatures shifted only 1.1°C to 1.4°C, bringing our global average to around 15°C.
How does this compare to Earth's broader history? It is drastically cooler than the planet's long-term baseline range of 18°C to 26°C, a threshold that characterised geological history before the current ice age era.
The climate narrative treats carbon dioxide as if it has somehow become a toxic modern pollutant, omitting the fact that CO₂ levels have been sitting at historic low levels for millions of years. Historically, these depleted levels—dropping to a ~180 ppm floor during glacial peak levels—led to hyper-aridness, expanding dry savannahs and severely reduced global biomass.
The natural baseline of our planet demonstrates that warmth and elevated carbon are primary drivers of a greener biological expansion. To generate catastrophic sea-level models, computer simulations would require a rapid, uniform melting of global ice caps. But this scenario ignores planetary geography. Past ice-melts came from vast prehistoric sheets—like the Laurentide and Fennoscandian—which extended far into mid-latitudes. They all melted long ago.
This were far more vulnerable to solar warmth than today's polar ice caps sitting over the Antarctic landmass and Arctic Ocean basin. The poles are oceanographically and meteorologically isolated from warm tropical currents. Because of this, a sudden, runaway collapse of polar stability is structurally impossible. The entire system is anchored by deep ocean dynamics that models consistently oversimplify.
Even if we looked at extreme historical melt events, the mathematical models behind today's 'climate doom' scenario would all collapse.
Following the end of the Last Glacial Maximum 19,000 years ago—when massive, vulnerable ice sheets sat directly exposed on land across Europe and North America—the average rate of sea-level rise was only 1.33 cm per year over a 9,000-year thaw, not even crawling pace.
