The Younger Dryas is also a Blytt-Sernander climate period detected from layers in north European bog peat. It is dated approximately 12,900-11,500 BP calibrated, or 11,000-10,000 BP uncalibrated.

Evidence is accumulating for a wider, perhaps global, extent, but the Younger Dryas was most strongly felt around the North Atlantic Ocean. Changes in the thermohaline circulation of the oceans are widely believed to be implicated in the onset and ending of the Younger Dryas cooling.

Определение в английском языке: Younger Dryas. The Younger Dryas was a period of climatic change, but the effects were complex and variable. In the Southern Hemisphere and some areas of the Northern Hemisphere, such as southeastern North America, there was a slight warming.. 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 most extraordinary thing about the Younger Dryas is how quickly it started, whatever its cause turns out to be. It had been believed for some time that it had taken hold in as little as a few centuries, this was later revised down to a few decades Более молодое Dryas увидело быстро возвращение к ледниковым условиям в более высоких широтах северного полушария между от 12.900 до 11.

The Younger Dryas is a climatic event from c. 12,900 to c. 11,700 years ago . 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. A hypothesized Younger Dryas impact event, presumed to have occurred in North America around 12.9 ka BP, has been proposed as the mechanism to have initiated the Younger Dryas cooling. The end of the Younger Dryas has been dated to around 9600 BC (11550 calendar years BP, occurring at 10000 radiocarbon years BP, a "radiocarbon plateau") by a variety of methods, with mostly consistent results Three temperature proxies showing the Younger Dryas event at around 12,000 years BP.

The Younger Dryas saw a rapid return to glacial conditions in the higher latitudes of the Northern Hemisphere between 12,900-11,500 years before present in sharp contrast to the warming of the preceding interstadial deglaciation. 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. The Younger Dryas is one of the most well known examples of abrupt change.

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.
