The most obvious way is that the sea ice is melting more and more every summer. Global warming happens everywhere because winds blow carbon dioxide (CO2) emissions all round the world.

Global warming is not seasonal, or annual. It is gradually increasing all the time.
If global warming continues, then the Arctic will become ice free.The frozen tundra soil will melt releasing vast reserves of methane (CH4) trapped in the ice. This methane (a powerful greenhouse gas) will add to the warming.Animal habitats will change and all animals will live on land.
The BP oil spill has very little to do with Global Warming or how fast the arctic ice floes melt. Its main effect is pollution.
The American Policy Center (APC) say this because they are global warming skeptics. They believe that global warming is not happening.

because of the global warming
global warming
global warming, for one.
All (current) global warming is the result of an increased abundance of heat trapping gas. As the arctic regions warm, methane gas trapped in permafrost soil is being released, accelerating the global warming effect.
The observed warming is amplified in the Arctic, yes.
The North Pole, the Arctic, is showing more signs of global warming than anywhere else.
because of global warming
Yes, every year Arctic ice gets smaller and smaller.
Your premise is incorrect; humans have not "destroyed the arctic environment".
they will melt
If global warming affects the ozone hole, the UV will come in. This will lead to more global warming.
