Warming up the Arctic

Arctic Lake Sediments Show Warming, Unique Ecological Changes In Recent Decades

I didn't know this:
....recent warming around the Arctic is overriding a cooling trend caused by Earth's periodic wobble. Earth is now about 0.6 million miles further from the sun during the Northern Hemisphere summer solstice than it was in 1 B.C. -- a trend that has caused overall cooling in the Arctic until recently.
The study indicates marked increased warming since 1950. Although, I have to say, didn't we know that already from thermometers?
