What is the tundras temperature?

The tundra is the coldest biome in the world.The latitudes of which the tundra is located is 55 degrees-75 degrees N. The Tundra is notable for having longest winters and the shortest summers.The land in the tundra is usually frozen grass and frozen land. There is a lot of tall grass and very few trees. The ground can be permanently frozen from 10 inches-3 feet deep. Winds frequently blow up to 30-60 miles per hour.

Human Imact

Every year, thousands of tourists aboard luxury cruise ships depart from ports in North America and Europe to experience the austere beauty of the Arctic, creating more pressure on the ecosystem. The tourism industry, including sport fishing and hunting, has also increased the volume of noisy airplane and helicopter traffic, raising levels of air pollution and sparking panic leading to egg loss in bird colonies. Plant life trampled underfoot won’t regenerate for decades and no disposal facilities exist for garbage left behind on the permafrost by human visitors

Issues

About 14,000 years ago, the Arctic climate began to change, resulting in massive extinctions of Ice Age plants and animals. Today, many scientists fear that history may be repeating itself. The depletion of the protective ozone layer over the polar regions, caused in large part by the chlorofluorocarbons used for decades as aerosol propellants and refrigerants, has allowed sunlight to heat up permafrost, which stores massive quantities of carbon dioxide. As this “greenhouse gas” is released into the atmosphere, ground temperatures rise further, prompting deeper melting of permafrost and speeding up the warming process. The Pew Center on Global Climate Change warns that as a consequence of rising land temperatures, a meltdown of polar ice masses could contribute to a rise in sea levels and cause widespread flooding of coastal areas around the world. Other experts, such as Professor Greg Henry of the University of British Columbia, predict that this could happen within the next few decades.
