First Canadian Slap Brewing
What if winter....never came? That's not going to happen anytime soon, and frankly it would be a very bad sign if the flakes didn't fly and the winds didn't howl and the temperatures didn't tumble. It would mean we were past the point of no return. The arrival of winter is a reminder that we haven't irreversibly screwed things up, at least not yet. I'm happy to report (on some level) that winter is, in fact, coming...
The first real Canadian slap of autumn is brewing for the first weekend of October, when you might actually need a jacket.
Your drip-dries may be drooping after yesterday's June-like downpours. Morning puddles give way to gradual clearing later today. The weekend still looks partly-glorious with sunshine and highs near 80F. Soak it up because we cool into the 60s early next week; in about 2 weeks we may be looking at highs in the 40s and 50s.
You know, actual autumn-like weather, for a change.
It's still supernaturally green out there for late September. Minnesota's growing season is 2 weeks longer than it was a generation ago. That's not a nebulous climate model; that's based on actual NASA observations of greenery from low-Earth orbit.

Californians Fear El Nino's Dark Side Will Bring More Trouble. Floods...in the midst of the worst drought in 500 years? It's a distinct possibility as El Nino warming of the Pacific shifts the core of the jet stream, the main storm track, 500-1000 miles farther south than typical during the winter months. But will this pattern actually emerge in the coming months? Here's a clip from Bloomberg Business: "...They weren’t touting it as the savior that will end the state’s four-year drought. Instead, they were looking at a darker scenario where the weather-changing phenomenon adds another year of dryness in the north while ravaging the south with floods. “What do you say when the governor asks you what to do? ‘You prepare for flood and drought because there is a possibility you can get both,”’ said Mike Anderson, state climatologist. While it bucks conventional wisdom, the scenario is a real possibility..."

The revelations of the Exxon research, and the fact that it was kept secret and all that, is an interesting story. And, that story will develop over coming days, week, and months. But I don’t want to lose track of the other story, in some ways even more interesting. How surprised should we be, after all, that a major corporation would both look into and ignore, possibly even repress, the science associated with their primary activity? Not at all, really. But what is surprising is that we (and by “we” I mean scientists who have studied climate change) have understood the basic problem for a very long time, and decades of research have confirmed early findings, and of course, added important details...."
