The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates .
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal ...
The scheme goes on to divide the Boreal (BO) into BO-1, 9300–9000, BO-2, 9000–8500, and BO-3, 8500–8000, incal. CalPal used on these dates suggests overall boundaries of 11,500 and 10,500 BP for the Pre-Boreal, and the end of the Boreal at 8900. Dates given recently are usually earlier than those given more than 10 years ago.
Boreal (age), the first climatic phase of the Blytt-Sernander sequence of northern Europe, during the Holocene epoch; Boreal climate, a climate characterized by long winters and short, cool to mild summers; Boreal ecosystem, an ecosystem with a subarctic climate in the Northern Hemisphere; Boreal forest, a biome characterized by coniferous forests
The Boreal kingdom or Holarctic kingdom (Holarctis) is a floristic kingdom identified (1947) by botanist Ronald Good [1] (and later by Armen Takhtajan), which includes the temperate to Arctic portions of North America and Eurasia. Its flora is inherited from the ancient supercontinent of Laurasia.
Throughout Earth's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than one million years ...
Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
Pre-Boreal sharp rise in temperature over 50 years (B-S), precedes Boreal 8500–6900: Boreal (B-S), rising sea levels, forest replaces tundra in northern Europe 7500–3900: Neolithic Subpluvial/African humid period in North Africa, wet 7000–3000: Holocene climatic optimum, or Atlantic in northern Europe (B-S) 6200: 8.2-kiloyear event cold ...
