Study: Massive Abrupt Warming During Past Low-CO? Era

General • February 11, 2026

Study: Massive Abrupt Warming During Past Low-CO? Era is drawing significant interest across the industry.

A new pollen-based reconstruction study shows Greenland warmed 10–16°C within decades during 11 Dansgaard–Oeschger events between 57,000 and 29,000 years ago, when atmospheric CO? was near 200 ppm. These globally expressed, circulation-driven shifts demonstrate that rapid, large climate changes occurred naturally under low and relatively stable carbon dioxide levels.

Experts suggest this could influence future trends and innovation in the sector.

More updates are expected as the story develops.
