The Five Boro Bike Tour is an awesome 40 mile ride through NYC. I highly recommend it. This year I did a slightly modified version so I could stop at 44 miles. But it meant I got to see the NYPD escort the lead pack of 32,000 bicycles out of Central Park in style!

Huge wildfire burning in the Hamptons. Many of the trees in this area have died from pine-beetle infestation, & the whole tip of LI is "abnormally dry" after a year of on-and-off drought. And this is one of the richest parts of the country. Yes, #ClimateChange IS going to hurt the affluent too.

The stratospheric polar vortex will be in strong vortex mode at Christmas, with average zonal winds at 10 hPa reaching over 60 m/s. The last time we had such a strong vortex in December was nine years ago, in 2015 (as per NASA MERRA-2 reanalysis: ozonewatch.gsfc.nasa.gov/meteorology/...).

We've seen massive N2O plumes in NYC over the years and it took me forever to link it to a wastewater treatment plant 3(!) km away. I just couldn't believe something that far away could be the source. But seeing ppm levels of N2O outside the plant made me a believer! Lesson: measure N2O in cities.
