In the wake of punishing heat waves, historic droughts, extensive flooding and extraordinary melt activity on Greenland, many are asking if we are seeing long-predicted results of climate change, caused primarily by man-made heat-trapping greenhouse gas emissions. A recent opinion editorial in USA Today argues against linkages between extreme weather and climate change. There are several issues with the USA Today opinion piece that must be addressed.

We felt that we could learn more about the lightning that we see flashing across the sky by investigating the data behind the flash, such as where it originated, where it traveled, its elevation, and where it struck ground.

Cool thoughts: awaiting an epic swim across Lake Michigan by local couple

By Don Lipman

In mid-August, at the 50-mile wide mid-point of Lake Michigan, a once-local couple now living in the Grand Rapids, MI area, will attempt a staggering 30-35 hour swim across the lake, one never before accomplished by a husband-wife team. Jeff Tow, who, as a youngster, swam competitively in Montgomery County, MD, and his wife Sara, have been preparing for this swim all their lives.

The setup was simple Friday (June 22) evening. A cold front would clash with a blistering hot and humid air mass parked over the mid-Atlantic and Northeast. The atmosphere had all the fuel it needed to trigger some severe thunderstorms. It did that, and damaging winds, torrential rain, and hail raked a narrow area that spanned from Bethesda, Md. through northern Washington, D.C into Landover, Md.

If you’ve enjoyed these bright, sun-filled evenings for an outdoor barbecue or a neighborhood stroll, the summer solstice tonight marks the culmination of our long-lasting daylight. At 7:09 p.m. (EDT) today, the sun will shine directly overhead at the Tropic of Cancer while the North Pole reaches its maximum tilt towards the sun.
