Historical climate changes more extreme than modern warming claims. 1969 study by Dansgaard et al. showed dramatic temperature fluctuations During the climatic optimum, temperatures were warmer than present day During the Little Ice Age (ended mid-19th century), temperatures were significantly colder

A 1969 study by Dansgaard et al. demonstrated that historical temperature fluctuations far exceeded modern variations. During the climatic optimum, temperatures were warmer than today with sea levels 2-3 feet higher, while the Little Ice Age ended only in the mid-19th century with significantly colder conditions. The documented swings between these extremes dwarf current climate changes, revealing that Earth's climate has experienced far more dramatic shifts throughout recent geological history.
