Warming trends have negative and positive results everywhere. Sure it will cause some problems in Alaska. But it will also open many closed doors. As drought wipes out mid west food production, Alaska could become the bread basket of the world. Black spruce permafrost forest will turn into something more productive and benefit humans and wildlife. I work outside all winter. I like the warmer temperatures. It make me money. We Alaskans will use less fuel too heat our homes. We can start helping the environment by implementing a pollution tax on imports made with old dirty technology and by not allowing cheap disposable goods to be imported. Things should be made to last and be repairable and recyclable. We have been exporting pollution and importing trash. Stop wasting energy on that and we will have a good start. Every time I drive past Ferry, GVEA's wind turbines are not spinning. Why not? 
It will be a long time or never before we heat our homes/businesses/cars with renewables
