For decades, we've been bombarded with catastrophic predictions from climate scientists, politicians, and activists. The message has been consistent: even slight warming from greenhouse gas (GHG) emissions will trigger catastrophic melting of the Greenland ice sheet, drowning coastal cities and plunging the world into chaos. The Intergovernmental Panel on Climate Change (IPCC), viewed by many as the gold standard of climate authority, consistently portrays Greenland as one of Earth's most vulnerable regions to warming. We're told repeatedly that Greenland's ice loss directly and rapidly translates into catastrophic global sea-level rise.

But here’s the uncomfortable truth, one that climate alarmists conveniently overlook: Greenland has been dramatically warmer in the past, and yet sea levels were significantly lower than today. How can this possibly be true if our entire understanding of warming and sea-level rise is supposedly settled science?

The Holocene Contradiction
The Holocene Thermal Maximum (HTM), around 9,000 to 5,000 years ago, provides a powerful historical reality check. During this period, Greenland was a staggering 4–8.5°C warmer than today, according to a comprehensive study published in the Proceedings of the National Academy of Sciences, a journal I have also published in.
