Late in the last century scientists published reams of data about Earth’s climate derived from ice cores taken from Greenland and Antarctic glaciers. By drilling down into the ice with hollow bits (think of using a spinning pipe as a drill) workers were able to pull columns of ice up to the surface.
These are the good times. I was driving through the country last Saturday, looking at deer happily chowing down in wheat fields. Everyplace is a drive-through if you’re a herbivore at this time of year.
