A Tough Winter?
It's human nature to compare and contrast. Yes, after March 2012 - the warmest March on record for Minnesota and the USA - 2013 has featured an old fashioned March: nearly 14 inches of snow, with temperatures 6.3F colder than average. But the claim of a tough winter? Not so much.
Your Honor, look at the evidence in Exhibit A: 49.3 inches of snow so far. Average for an entire winter is 54". Based on Heating Degree Days we've actually saved 1.5 percent on heating costs this winter season. Subzero nights in the metro: 9. The latest 30 year average is 22.5.
Truth? We've been so pampered and spoiled since roughly 1998 - even an "average winter" seems like a cold slap across the face.
Highs approach 50 today (I may take off my shirt and fire up the grill - just to annoy the neighbors) before a half inch of rain falls Saturday morning. A colder front arrives Easter Sunday on gusty winds. Expect bright, ineffective sun and wind chills of 15-20F for Monday's Twins Home Opener. Hey, who needs a retractable roof?
The sun angle is similar to mid-September, so it can't stay chilly for long. With our reluctant spring I wouldn't be surprised to see a few more slushy inches in April, but highs approach 50 next Wednesday, again the first weekend of April. Slow, tentative signs of a tardy spring.

- Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years. This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.
- As suspected, much of the 'missing heat' Kevin Trenberth previously talked about has been found in the deep oceans. Consistent with the results of Nuccitelli et al. (2012), this study finds that 30% of the ocean warming over the past decade has occurred in the deeper oceans below 700 meters, which they note is unprecedented over at least the past half century..."

Field and Stream: The Conservation Hawks is a new group dedicated to harnessing the power of sportsmen to address climate change. Stop. Before you give in to anger, or to the “conservation fatigue” that can fall upon us like a giant wet carpet whenever climate change is mentioned, consider this: If you can convince Conservation Hawks chairman Todd Tanner that he’s wasting his time, that he does not have to worry about climate change, he will present to you his most prized possession: A Beretta Silver Pigeon 12 gauge over/under that was a gift from his wife, and has been a faithful companion on many a Montana bird hunt. I know the gun, and I’ve hunted and fished with Todd for years. He’s not kidding. You convince him, he’ll give you the gun..."
