Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification . It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F ...
The tundra is an extremely harsh, cold, windy, and unique ecosystem found on the extreme north and south latitudes of our Earth. The soil consists mostly of frozen permafrost, which makes it difficult for extended root systems to grow, and water to drain and support a wide variety of plant life.
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
Geographical locations where the tundra biome is found. Tundra is found north of 70° N latitude in North America, Eurasia and Greenland. It can be found at lower latitudes at high elevations as well. [42] The average temperature is −34 °C (−29 °F); during the summer it is less than 10 °C (50 °F).
The Summary. This was the Arctic’s second-hottest year on record, according to a new NOAA report. The tundra has become a source of emissions, rather than a carbon sink, the authors said.
