The tilt of the earth changes the angle at which sunlight hits Alaska. The more direct angle of the sun during summer creates much greater heating.

Alaska has a squarish sort of shape. Some parts of it are a long way from the sea, so they have a continental climate. Hot summers and cold winters. The sea has a moderating effect on temperatures. And the prevailing winds for all except the far north are westerly, so you get air from the middle of Siberia, which has an even more extreme continental climate.

Think about it -- the sun doesn't set for weeks at a time. That's a lot of heat.
And the opposite is true of the winter weeks of darkness.
