Weather is inherently mysterious. Multiple forces, such as wind, clouds, seasonal and day-night cycles, and air pressure are constantly interacting and causing continuous chaos. In the aftermath of two particularly destructive hurricanes, the fear-mongers are bloviating to the max over the catastrophic effects on the climate caused by human existence.
And yet there is no discernible trend toward either more storms or more intense hurricanes compiled over more than beyond the last century. (This chart by NOAA was especially easy to find.) Thus far, the decade of the 1940s saw the most seriously intense storms. Being historical data, this brings to mind a modification of Santayana’s famous adage: when people are ignorant of their history, they make it really easy for demagogues to lie to them about it.
Rather than human consumption of fossil fuels, two other factors are mostly relevant when it comes to the damage wrought by hurricanes: the path they take and the development of infrastructure within that path. Out on the open sea, a hurricane may damage a few ships, but when one goes over a population center…well, you know, it just happened.
What determines the path is largely chaotic. Go figure. There’s this weird thing called the jet stream, which is sort of the result of the Earth’s continuous rotation within a tenuous atmospheric envelope. Becoming known to American aviators during World War 2, the particular details of the jet stream were kept as a military secret well into the mid-twentieth century. Ocean currents and surface temperatures are also involved. Early forecasts of hurricane paths are typically all over the map. As the time frame compresses, they tend to become more accurate, but not always.
Then there’s the “atypically” warm weather that sometimes happens in early autumn. We just had some of that, along with offshore winds and seriously elevated fire danger. In the olden days, this was called “Indian summer.” Back in 1919, Victor Herbert even wrote a song by that name. Maybe I’m just a cynic, but I’m expecting the fear-mongers to start pandering to the general public’s pervasive ignorance of earth science to cause panic over yet another routine weather event.
