Global Warming

The Arctic is warming faster than the rest of the globe and is experiencing some of the most severe climate impacts on Earth. One of the most notable is the rapid decline in the thickness, age and extent of sea ice. Thiner and younger ice melts much faster, and scientists are predicting that by 2030, the Arctic Ocean will be entirely ice-free in the summer.



Why is that a problem? Sea ice underpins the entire Arctic marine ecosystem, and as it shrinks and thins, there are major repercussions for the Arctic peoples and wildlife. Many polar species depend on the ice to survive - polar bears are the most famous example, but ringed seals also spend most of their time on ice, travelling North to find thicker, more stable one. The Arctic is still under-explored and many more species could be touched by the melting ice cap than we even know of.

The Arctic is also one of the regions where the feed-back effects from Global Warming are the most dire. As the white ice cap is replaced with dark seas, sun light is less and less reflected by in space, allowing for more warming to happen on the planet. The quantities of methane contained in the permanently frozen ground (permafrost) in the tundra is also a major problem: as the ground melts, more methane (one of the most potent greenhouse gases) is released in the atmosphere, accelerating global warming.



In particular, the ice laying on top of the land mass, like in Greenland, will contribute to sea level rising. The ice sheet has been melting faster than ever in recent years, as the summer 2009 Greenpeace expedition demonstrated.

These are factors humans cannot control, and if we are to solve the climate crisis, we have to do it before these feedback effects get beyond recovery.

Increased exploitation

As the sea ice melts, more exploitation is possible. Geologists believe that that one third of the planet's crude oil is located under the sea-bed. Unfortunately, the lessons that should be taught on how much disaster is caused by current oil exploitation - from oil spills to the very global warming that opens these oil fields for exploitation. Arctic States are trying to expend their sovereignty over the sea-bed as far as they can. The Norwegian government is already implementing plans to open an oil platform.
Open seas also mean more shipping. More shipping means more risks of grounding, oil spills and chemical spills. Both poles are far more vulnerable than the rest of the planet to oil spills. The low temperatures, lack of light as well the small amount of search and rescue stations means that any accident is going to have a long lasting impact on the environment. Look no further than the infamous Exxon Valdez grounding for this. 20 years after it happened, oil is still leaking from under rocks in the Prince William sound.

Oil can irritate the skin of some Arctic species, and reduce their defenses against the cold. Bird feathers can also become entangled in the oil and prevent them from flying. Most of the time, they laos ingest the oil and inhale some toxic fumes.

Long-range pollution

A lot of pollution in the Arctic doesn't orginate there. Air and marine currents bring the toxic chemicals that are emitting in Eurasia and North America. These are then ingested by fauna and flora.
The amount of mercury found in fauna hunted by the aborigene population currently excedes the commonly agreed food-safety levels. These levels also contribute to further endangering species already facing a number of threats.
Persistant organic pollutants like DDT, DDE and other pesticides also find their way to the Arctic, where they are almost never used, since there is no agriculture there.

The greatest tragedy of the Arctic, is that the damage of global warming and transboundary pollution is caused thousands of kilometers away, and the native inhabitants are laregely powerless to stop the destruction of their environment.
