We always suspected that Greenland was sneaky...

Greenland icebergs may have triggered "big freeze."

From the article:

In a warming world, what could cause temperatures to suddenly plummet across the Northern Hemisphere? Scientists have tried to answer this question for decades, ever since they discovered geological and biological evidence for the "Big Freeze."

Now, a new study points to an armada of icebergs or meltwater from Greenland as a possible cause for the sudden climate change called the Younger Dryas, or the Big Freeze. The findings were published online July 10 in the journal Earth and Planetary Science Letters.

Specialty words....

So, I am copy editing along in Night Calls, and I reach where Allie is binding stooks...and the actual novel was edited to say "binding shocks of corn" which is almost the same thing. But not quite--a stook has a different meaning in the US and in the UK, and sheave is closer to the old meaning of the word "stook." "Shocks of corn" also works and should convey meaning to multiple groups of people.

I was lucky in my original Night Calls copy editor, even if we occasionally disagree.
