As the Captain: What Happens When Lightning Strikes a Plane? An interesting response at The Detroit Free Press: "...Lightning strikes will usually leave small burn marks or holes at the entry and exit point. Airplanes are designed to allow lightning to move along the skin of the airplane without doing damage. Occasionally, a static wick will be the victim of lightning exiting the airplane. I have been in airplanes that have sustained lightning strikes several times with very little damage.... In the air, airplanes are designed to dissipate the lightning quickly. I have been flying airplanes that were struck multiple times, and there was little or no damage sustained. All the surfaces are bonded, giving the lightning a pathway to pass back into the atmosphere. On the ground, there is a risk to people on the ramp if the airplane discharges the lightning. For the passengers, there is very little or no risk in either situation..."

Job-Stealing Robots? Millennials See Hope, Fear in Automation. Every threat is an opportunity, right? Here's a clip from LinkedIn: "...Dramatic shifts in the how and the where of the future of work recently prompted my 15-year-old to ask, “Mom, are robots going to take my job someday?” Timely question. Deloitte Global’s latest survey of millennials shows many are asking the same thing. While they recognize the benefits of automation in terms of productivity and economic growth, they also see it providing opportunities for value-added or creative activities, or learning new skills:
- 40 percent see automation posing a threat to their jobs;
- 44 percent believe there will be less demand for their skills;
- 51 percent believe they will have to retrain; and
- 53 percent see the workplace becoming more impersonal and less human. Which is news that should make every CEO sit up and take notice, given this generation’s use of social media..."

More Extreme Weather Coming After Record 2016 Heat, WMO Says. Bloomberg provides more perspective on the WMO report: "Unusually warm weather in the Arctic is helping shift weather patterns this year from North America to the Middle East, after global warming shattered records in 2016, according to the World Meteorological Organization. Rising ocean temperatures that are melting polar ice sheets, killing marine life and flooding coastal communities may have increased more than previously reported last year, the WMO said in a report Tuesday. Average sea-surface temperatures hit their highest levels ever last year, and overall temperatures over sea and land were 1.1 degrees Celsius above the pre-industrial period. At least three times this winter, the Arctic has experienced the polar equivalent of a heat wave with Atlantic storms driving warm, moist air..." (Map credit: NOAA NCDC).
The Seasons Aren't What They Used To Be. Here's an excerpt of a poignant piece at The New York Times: "...Spring has been particularly hasty and irregular this year, but this is no anomaly. In the latter half of the 20th century, the spring emergence of leaves, frogs, birds and flowers advanced in the Northern Hemisphere by 2.8 days per decade. I'm nearly 50, so springtime has moved, on average, a full two weeks sinnce I was born. And you? We now experience climate change not only through the abstraction of science, but also through lived experience..." (Image credit: NOAA).

Climate Change is Certainly Causing More Powerful Storms. Here's a clip from an article at Salon: "...The ‘100-year flood’ now occurs more often than once a century,” Hansen said. Michael E. Mann, Director of the Earth System Science Center and Distinguished Professor of Meteorology at Penn State University, observed that the warming climate is actually causing more snow. “The oceans have been at record levels of warm the past two years (and climate change is a key contributor to that),” Mann said. “That record warmth means that there is more moisture in the atmosphere that is available both to help strengthen the storm and produce record snowfalls as the warm oceanic air is entrained in toward the eastern U.S. by the cyclonic winds of the storm. Climate model simulations indicate a likelihood for stronger, more snow-making storms, and that’s what we’re seeing...”
