The UK Column chaps ended their bulletin today on a light note. They had picked up a meme showing an image of a teacher addressing her near future back-to-schoolers, “So children, what did we learn during lockdown?”

Adult education for me today included this –

The conversation that accompanies this cautionary note is enlightening. If you watch it, the Google algorithm will recommend Part 2. In this, John Doyle references the blue ocean event, global dimming and the dangers of wet bulb temperatures. When I gathered my data at Weather Underground this morning I noticed Category 6  had just posted Heat and Humidity Near the Survivability Threshold.

There is still no sign of a sudden rise of temperature in any of my Ten Stations (as a consequence of a less polluted atmosphere). Running average temperatures from the beginning of the meteorological year over the last five weeks show:-

4 of the northern 5 stations are warmer than in the same period last year but at only one, Rome, is it currently getting relatively warmer. Washington was warmer than last year (just) until last week.

Washington DC is the only northern station currently below 2°C above P-I.

All 5 southern stations are now cooler than the IPCC projection for the end of November 2020.

Wellington is now the warmest of the southern stations this year at 1.06° above P-I exactly. (The IPCC year-end projection is 1.0652 degrees.) But in Week 23 it was 0.55°C cooler than last year, up 0.35 degrees from Week 19.
