April 5, 1999: Heavy snow falls over the Arrowhead, with 11 inches at Two Harbors.
April 5, 1929: A tornado cuts a path from Lake Minnetonka through North Minneapolis and leaves six dead.
The average lead time for tornadoes has risen from 4 minutes to 13 minutes in the last 30 years. It's getting harder, with a straight face, to say "there was no warning!" But challenges remain.
A December 26, 2015 EF-4 tornado in Garland, Texas, near Dallas, claimed 9 lives; many swept off freeways as a tornado churned through the suburbs after dark. Impossible to see, illuminated by flashes of lightning, it represents a worst-case scenario. How do you adequately warn people in their cars? New digital billboards provide some level of warning. Another solution may be GPS-specific alerts on smartphones. Situational awareness is critical - knowing when there's a tornado watch in the area.
ExxonMobil Is Increasingly Being Singled Out for Its Role in Climate Change Deceit. Here's the intro to an update at VICE News: "The US oil major ExxonMobil once faced just two state attorneys general who were investigating whether or not the company lied about climate change. But, the number of top prosecutors questioning the company grew to seventeen this week, just as another major philanthropic organization said it would divest from ExxonMobil. The New York Attorney General's office launched in November an investigation into whether ExxonMobil is guilty of making false or misleading statements to investors about climate change and its potential impact on the company's bottomline..."

Tesla Model 3 Is Already World's Most Popular Electric Car. Newsweek has the latest numbers; here's an excerpt: "Tesla founder Elon Musk has revealed the firm’s much-anticipated Model 3 electric car has received 276,000 pre-orders worth almost $10 billion in just two days. At $35,000, the Model 3 is Tesla’s first vehicle to eschew a high-end price tag and aim squarely at mass-market adoption. The similarly priced Nissan Leaf electric car has sold more than any other pure-electric vehicle, passing the 200,000 unit milestone in December 2015..."
The Electric Car Revolution Is Now Scheduled for 2022. Six years away? Our grandkids won't think twice about driving EV. Gas-powered vehicles that are more expensive to produce and maintain may become the rough equivalent of rotary phones. Here's the intro to a story at WIRED.com: "The long-awaited, oft-delayed electric car revolution is now scheduled for 2022. That’s according to a report from research firm Bloomberg New Energy Finance, which posits that in just six years, the biggest obstacle to the sale of EVs—they cost too much—will be obliterated and cars that run on electricity will cost less than those that run on dead dinosaurs. “By 2022,” the report says, “the unsubsidized total cost of ownership of BEVs [battery electric vehicles] will fall below that of an internal combustion engine vehicle..."

We've Been Getting These Key Details About Greenland's Melting All Wrong. It's not just surface temperature increases and carbon soot accelerating melting of ice; it's also surrounding water. The Washington Post reports; here's an excerpt: "...It’s also believed that warm ocean water can help destabilize glaciers from the bottom up, melting the ice where it’s grounded to the seafloor and eventually causing large chunks to break away. Truffer pointed out that it’s “only in the last 10-plus years that people really started realizing how much of a role melting by ocean water played.” So scientists are still getting a handle on the kinds of information we need to really understand the process. And one under-studied part of the picture is underwater topography..."
