It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. Alpine tundra has a more moderate climate: summers are cool, with temperatures that range from 37 to 54 °F (3 to 12 °C), and winters are moderate, with temperatures that rarely fall below 0 °F (–18 °C). One constant factor shaping the tundra is a pattern of freezing and thawing of the ground. As the tundra heats up, it is releasing more carbon dioxide and methane (two types of greenhouse gases, that trap heat in the Earth's atmosphere) into the atmosphere.
Precipitation totals 6-10 inches of rain a year, which includes melted snow. This is almost as little as the world's driest deserts. Coupled with strong and drying winds, the tundra is an extreme weather biome. The tundra is the coldest of all the biomes with an annual average temperature of less than 5°C, and precipitation (mostly in the form of snow) less than 100 mm per year. The weather conditions at tundra are so harsh that only a handful of plants and animals can even survive there. The tundra climate is called many things, one of them is “the land of endless night” for its long winter darkness.

The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome. Its underlying base of frozen soil and plant matter, called permafrost, is thawing.

Description. Understanding the sensitivity of tundra vegetation to climate warming is critical to forecasting future biodiversity and vegetation feedbacks to climate.
Some animals in the tundra are adapted to the climate by breeding and raising their young in the summer. Many animals hibernate, or sleep during the worst part of winter to minimize energy loss. Because animals of the tundra are generally migratory, this biome's population is constantly changing. Alpine tundra has a more moderate climate: summers are cool, with temperatures that range from 37 to 54 °F (3 to 12 °C), and winters are moderate, with temperatures that rarely fall below 0 °F (–18 °C). One constant factor shaping the tundra is a pattern of freezing and thawing of the ground. However, the effects of climate change and human interference have been enormous in this region. Many animal species have lost places they once called home, thereby threatening the ecological balance of the region.
Climate. Since tundra is the coldest biome on the globe. Temperatures hardly surpass -18 degrees Fahrenheit or -8 degrees Celsius. In the month of June, the temperature can go up to 50 degrees Fahrenheit. Winters in the tundra are long, freezing and dark.
