The Weather Guy Says - It Ain't Your Grandpa's Weather Any More

He's not your TV weather guy. When he gets it wrong he's in trouble. Paul Douglas owns a company that provides weather forecasts to Fortune 500 companies that need to know what's coming and can risk a lot of money on his advice. He also, it seems, is an evangelical.

Douglas has written an excellent piece in The Guardian. Here are a few excerpts, teasers:

Whatever happened to normal weather? Earth has always experienced epic storms, debilitating drought, and biblical floods. But lately it seems the treadmill of disruptive weather has been set to fast-forward. God’s grandiose Symphony of the Seasons, the natural ebb and flow of the atmosphere, is playing out of tune, sounding more like a talent-free second grade orchestra, with shrill horns, violins screeching off-key, cymbal crashes coming in at the wrong time. Something has changed. the turn of the 21st century this warming seemed to be flavoring much of the weather I was tracking, turning up the volume of extremes, loading the dice for weather weirding. Multiple strands of data confirm Earth has a low-grade fever, a warming trend that transcends periodic heat released from El NiƱo.

People ask “What’s a couple of degrees, Paul?” Well, when was the last time youwere a couple of degrees warmer? Chances are you felt miserable. And there were visible, tangible symptoms: sweating, chills, headaches, nausea. Your physician popped a thermometer in your mouth and confirmed you had a fever. Chances are you didn’t make a fuss, argue with the doctor, or deny the diagnosis.

Both NASA and local farmers confirm a longer growing seasons, with more allergens, pests and invasive species. Rainfall rates are increasing; wet areas trending even wetter. My home state of Minnesota has witnessed four separate 1-in-1,000 year floods since 2004.

A warmer atmosphere is increasing water vapor levels overhead, juicing storms, fueling an increase in flash floods in the summer, and heavier winter snows along the East Coast of the USA. “All storms are 5 to 10 percent stronger in terms of heavy rainfall” explained Dr. Kevin Trenberth, at the National Center for Atmospheric Research in Boulder, Colorado.

From the mega-blaze that swept across Fort McMurray, Alberta to repeated flooding of Houston, scorching heat in India, perpetual drought from California to Australia, and a record year for global hurricanes, typhoons and cyclones in 2015, the symptoms of a warming ecosystem are becoming harder to dismiss or deny.

In a day and age of scammers, hackers, hucksters and special interests it’s good to be skeptical. You should be skeptical about everything. Some of the biggest skeptics on the planet are scientists. In fact, science is organized skepticism. Climate and weather are flip-sides of the same coin; everything is interconnected. Climate scientists tell us the climate is warming and meteorologists are tracking the symptoms: freakish weather showing up with unsettling regularity. Even if you don’t believe the climate scientists or your local meteorologist do yourself and your kids a favor. Believe your own eyes.
