BUMPED from August 17 AND UPDATED,
Turns out there is much more to this story which calls the "warming" earth temperatures into question. So, I have bumped it from its original posting date.
The numerals inside the white boxes are supposedly water temperatures of northern Lake Michigan °F (original here). A lake temperature of 325.5°F with others over 200°!
Someone should talk with the folks at Michigan State University about the boiling point of water.
