Arctic Tundra: Thesis About the Main Thing
A biome is a big region of Earth that has a certain climate and certain types of living creatures. the major biomes are tundra, forests, grasslands, and deserts. The plants and animals of each biome have traits that help them to stay alive in the biome They live in. The polar climate regions are characterized by a less amount of warm summers. there is an average temperature of less than 10°C Every month of the year in a polar climate. A polar climate has cool summers and very chilly winters, which end up in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice In the polar regions the Scientific information lifts our knowledge of the environmental issues facing the world in order to grip onto the challenges facing us, be it climate change, sea-level rise or pollutants.
Climate Change
Time flies is a saying which seems to become largely relevant, at least when it comes to climate change and mitigation. As Thomas Stocker, of the UN’s Intergovernmental Panel on Climate Change, said Ongoing greenhouse gas emissions caused later on in climate change and constitute a multi-century commitment in the time ahead the atmosphere is our usual resource, and it should not be used as a dump for all greenhouse gases in the world.
Sea Level Rise
White surfaces on the Earth's ice and snow cover reflect 80-90% of the solar energy heat. Darker surfaces open seas, land areas not covered by snow reflect only 10-15%. As the size of the arctic sea ice decreases and the Northern Hemisphere snow cover retreats, more open sea and vegetation will absorb more amount of energy. This leads to a feedback loop of warming in the seas and overland.
Ocean Acidification
Ocean Acidification in the worlds has become an important worry in the Arctic. There is a decline of pH in the water as an outcome of increasing carbon dioxide (CO2) in the atmosphere. The ocean absorbs more CO2, which in turn disturbs the balance of the marine ecosystem. Ocean acidification is of specific interest to Arctic countries, as the region is dependent upon fisheries. Ecosystems have adjusted to changes in the past, but now the changes are taking place at a rate which makes it not possible for many plants and animals to Modify.
Pollution
Another warning to the world has come through an international project to fight plastic waste in the seas. The Great Pacific Garbage Patch – approximately 3 times the size of Spain and Portugal – is one of several swirling garbage zones in the oceans. Tiny pieces of broken-down plastics, so-called microplastics, are a serious threat to millions of marine birds, sea turtles, fish, and other organisms in the sea. They block the sunlight for algae and plankton, and many animals that mistake these and larger pieces of plastic for food end up dying with bellies full of indigestible material. The plastics may also contain hazardous substances. It has been estimated that 1 million seabirds worldwide die of plastic waste every year.
