The growing season, when the vegetation in the taiga comes alive, is usually slightly longer than the climatic definition of summer as the plants of the boreal biome have a lower temperature threshold to trigger growth than other plants. Some sources claim 130 days growing season as typical for the taiga.
It is essential for climate change to be combated with global action, which is what the Kyoto Protocol in 1997 was created to do. Other measures to protect the taiga would be to prohibit unsustainable deforestation, switch to renewable energy, and protect old-growth forests, (they sequester the most carbon dioxide).
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 ...
This vast ecoregion is located in the heart of Siberia, stretching over 20° of latitude and 50° of longitude [1] (52° to 72° N, and 80° to 130° E). The climate in the East Siberian taiga is subarctic (the trees growing there are coniferous and deciduous) and displays high continentality, with extremes ranging from 40 °C (104 °F) to −65 °C (−85 °F) and possibly lower.
These seven can be divided into two main groups. The northern regions of the boreal forest consists of four eco-zones – Taiga Cordillera, Taiga Plains, Taiga Shield and Hudson Plains – that are the most thinly treed areas where the growing season and average tree size progressively shrinks until the edge of the Arctic tundra is reached.

Summers are cool and short in this sub-arctic climate, with mean temperatures ranging from 7 °C in the north to 14 °C in the south. [ 5 ] [ 6 ] Winters are long and very cold in the Mackenzie Delta, with a typical January mean of -26 °C, but are somewhat milder in the southern extent, with a mean January temperature of -15 °C.

The climates are typically humid for much of the year, usually appearing in the humid subtropical climate and in the humid continental climate zones to the south of tundra and the generally subarctic taiga. In the Köppen climate classification they are represented respectively by Cfa, Dfa/Dfb southern range and Cfb, [4] [5] and more rarely ...
While the taiga has a more moderate climate and permits a diversity of both non-vascular and vascular plants, [3] the tundra has a limited growing season and stressful growing conditions due to intense cold, low precipitation, [4] and a lack of sunlight throughout the winter. [5]
