1) Climate change in Alaska is happening because we are releasing chemicals and using lots of fossil fuel they also broke through the ozone layer and making the sun heat up,In result sea levels are rising from icebergs falling and melting.Then now temperatures are getting high and the normal temperatures are shifting.But some shifts are actually natural.

2) Its been affecting Alaska by temperatures rising by 1.4 degrees.Also icebergs has been melting making sea levels rise higher.Which is very dangerous as we lost land and animals and their home/habitats.

3) Stop wasting energy and using less fossil fuels and lowering ac and heaters to save energy.You can also use bikes or walk instead if using petrol with your car which releases chemicals.
