In the Southern Hemisphere and some areas of the Northern Hemisphere, such as southeastern North America, there was a slight warming.[1]. The Younger Dryas Boundary hypothesis, also known as the Clovis comet hypothesis, theorises that a large air burst or an earth impact of an object or multiple objects from space initiated the Younger Dryas cold period around 12 900 years ago.

The period from approximately 10 800 to 9600 BC when climate in the region around Greenland cooled by 57C within a few decades and recovered with similar rapidity at the end of the period named for the expansion of the geographic range of the arctic herb Dryas octopetala. An event that occurred about 12,800 years before present (BP), termed the Younger Dryas (YD), is the canonical example of abrupt climate change. It is best seen in the Greenland ice cores, although it had very marked consequences over Europe, North America, and as far as New Zealand. This near-glacial period is called the Younger Dryas, named after a flower ( Dryas octopetala) that grows in cold conditions and that became common in Europe during this time.

Past shutdowns of the Atlantic Oceans conveyor circulation appear to have played a key role in triggering the large and abrupt global climate changes that punctuated the last period of glaciation including the millennial duration Younger Dryas (Broecker and Denton, 1990). The Younger Dryas stadial, also referred to as the Big Freeze, was a geologically brief (1,300 70 years) period of cold climatic conditions and drought which occurred between approximately 12,800 and 11,500 years BP (before present). The Younger Dryas is a geological period between circa 10,730 BC and 9,700 99 BC).It is called after the Dryas octopetala flower typical for cold climate zones. The word younger is used to distinguish this period from other two periods the Oldest Dryas and the Older Dryas. The footprint of Younger Dryas climate change suggests that it was caused by a reduction in Atlantic meridional overturning circulation (AMOC) (Stouffer et al 2006), for which there has been growing evidence since the mid-1980s (Boyle and Keigwin, 1987). The Younger Dryas is a climatic event from c. 12,900 to c. 11,700 years ago (BP). It is named after an indicator genus, the alpine-tundra wildflower Dryas octopetala, as its leaves are occasionally abundant in the Late Glacial, often minerogenic-rich, like the lake sediments of Scandinavian lakes. The Younger Dryas impact hypothesis posits that a cosmic impact across much of the Northern Hemisphere deposited the Younger Dryas boundary (YDB) layer, containing peak abundances in a variable assemblage of proxies, including magnetic more.
