If I understand correctly he uses a dataset called CFSv2, which goes back to 1979, and then July 2019 is the 4th warmest on record after July 2016, 2002, and 2017.

If these were numbers (range 1979-2019, winning numbers 2016, 2002, 2017, 2019) that could be used to predict the odds of winning in a lottery then I would be very happy to use them and buy a 2020 lottery ticket.
