Arctic Climate Emergency

IMPORTANCE OF THE ARCTIC

IPCC 2007: In both polar regions, there is strong evidence of the ongoing impacts of climate change on terrestrial and freshwater species, communities and ecosystems (very high confidence). Recent studies project that such changes will continue (high confidence), with implications for biological resources and globally important feedbacks to climate.
 
In both polar regions, components of the terrestrial cryosphere and hydrology are increasingly being affected by climate change (very high confidence). These changes will have cascading effects on key regional bio-physical systems and cause global climatic feedbacks (very high confidence).

Continued changes in sea-ice extent, warming and acidification of the polar oceans are likely to further impact the biomass and community composition of marine biota

Arctic climate features

o The Arctic is a major component of the climate system.
o It's year round snow and sea ice coverage is sustained by the snow and ice extent albedo cooling effect.
o This albedo cooling sustains the temperate northern hemisphere climate, and thereby the world's best food producing regions.
o The albedo keeps permafrost permananently frozen and subsea methane gas permanently stable.
o The Arctic jas a great many unique species that depent on yearf round snow and ice.

The Arctic is a system with strong links between the ocean, land, and atmosphere and the ecosystems they support.

Consequently, the impacts of the shift in the characteristics of the Arctic Ocean reach well beyond the ocean itself, and are acting
together to amplify the evidence of change.

The albedo cooling effect of Arctic snow and summer sea ice is the air conditioner of the entire northern hemisphere and exerts some cooling to the planet as a whole.

The Arctic is one vast ecosystem that is a major component of the planet's climate system. As such, changes to the Arctic reverberate throughout the biosphere and far into the future.

The Arctic connects with and affects the world's oceans and atmosphere, and Arctic summer sea ice is a major determinant of the global temperature.

Because it is cold water, the Arctic Ocean is very vulnerable to ocean acidification.

The Arctic has many unique species like the polar bear that are are dependent on year round sea ice.

The Arctic is vital for a great many bird species.

There are bird species that inhabit the Arctic and also thousands of bird species that migrate to the Arctic from every region of Earth. No other place on Earth has so many bird species than the Arctic in this breeding season. Millions of birds use the Arctic for breeding
