In physical geography, a tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic , [ 2 ] Alpine , [ 2 ] and Antarctic .
The tundra is one of the first places on Earth we have noted the effects of climate change. As an indicator biome, the tundra is a crucial part of the whole global climate system and can help predict the changes the rest of the world will face.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Predicated changes for Earth's biomes under two different climate change scenarios for 2081–2100. Top row is low emissions scenario, bottom row is high emissions scenario. Biomes are classified with Holdridge life zones system. A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome ...
Because the Gulf Stream has a moderating effect, portions of Iceland have an Oceanic climate (subpolar variety) (Köppen climate classification: Cfc).But most of the ecoregion is Tundra climate (Köppen climate classification: ET), a local climate in 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 ...
This change contributes to the consideration that the tundra biome is currently experiencing the most rapid change of any terrestrial biomes on the planet. [ 83 ] [ 84 ] The direct impact on mosses and lichens is unclear as there exist very few studies at species level, but climate change is more likely to cause increased fluctuation and more ...
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 .
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]
