Snowball comet theory linked to Tunguska blast
Two geophysicists from Caltech presented computer model evidence at a Lunar and Planetary Science Conference supporting a half mile diameter snowball like comet hitting Russia in 1908. The collision would vaporize but not crater a forest, sending shock waves and flattening trees over hundreds of square miles. They argue atmospheric explosion is unlikely and note many comets are dense ice and debris while some are less dense like snowballs.

Butterfat declines with rising temperatures in Wisconsin
Wisconsin statistician Laverne Krahn notes butterfat averages fall about 0.3 percentage points as heat rises, lowering the state average to around 3.6 percent in hot weather from 3.9 percent in winter. He compares today’s trend with similar 0.3 point drops seen 20 years ago, while cautioning individual herds may vary as much as 7 to 8 points.
