Wait, Don, who cut down the trees at Easter Island? I thought only natives live there-- it's one of the most isolated places on the entire planet. If we are on that trajectory, we might not have Venus level greenhouse warming, but we'll likely get at least partway there. Is having the current generation of rich people die off going to be enough to end fossil fuels? I don't see anyone who is under 40 who would want to support or even run a fossil fuel company, so maybe we will be finally done with them when everyone who is currently over the age of 40 is dead?

ear Rank Days >= 100 °F 1911 1 4 a very hot summer, I wonder if NYC was similarly hot and had 100+ days in 1911 too?

Year Rank Days >= 95 °F 1949 1 14 1944 2 12 2018 3 9 1983 3 9 1955 3 9 2021 6 8 1953 6 8 1911 6 8 2022 9 7 2002 9 7 These years do match up with NYC well, what was going on in `1911 (the year before 1912 that we were discussing) that caused 4 100+ days in Boston in 1911? Didn't NYC also have a very hot summer with 100+ days in 1911 too?

very similar to JFK and NYC, 2010, 2002, 1991 and 1983 place prominently in the top 5! 1983 1 30 1955 2 28 2002 3 27 1991 3 27 2010 5 25

Our society is just too dependent on fossil fuels. Even with lessening of emissions as fuel, there is still the matter of plastic being created from toxic petrochemicals. The fossil fuel cartel does not want to be retired from existence, there's just too much money in it. We will probably eventually be completely done with it, but I don't foresee that happening for the next 50 years.

wild, nothing like what NYC had in 1953

Weird, Boston had 10 90 degree days in July 1912, it must have been over the top heat.

7-9-1912 when Boston hit 99, NYC might have hit 100 on that day. 7-9 is a popular day for extreme heat, I think that was the last day of a 3 day 100+ stretch at NYC in 1993, when we hit 102 degrees.

I wonder if NYC had a similar hot stretch to Boston in 1912.

whats causing all the stalled fronts and cloudy weather in July which we did not have in the 90s especially?

This would then also mean much more snow changing to rain or outright rain storms in the winter because of onshore flow.

I tried the multiquote thing after a browser update and it works a little better but still scrolls me down to the end of the page and I have to go back up to find the posts I wanted to quote lol. Excellent work Tony, it's interesting how JFK's hottest August temperatures happened at the start of their POR and the only time they had two 100+ in a row in August, in 1983 they also had 2 100+ temperatures, but one was in July and the other one in August. In September 1983 came the closest, which was our hottest September on record (like how 1991 one was for May.)

Eastern Canada and especially northeastern Europe and western Asia are very strong hot zones wow.

why are they scraping the NAM?

Don does the deep red area show where the temperature anomalies are the greatest in the positive direction?

It's the same excuse Big Pharma uses for higher drug prices, none of that goes into R&D it mostly goes into marketing and corporate / shareholder pay.

Is this shift in summer circulation patterns cyclical? I can't see why it would be connected to climate change in any way. Rainfall yes, but not circulation patterns.

It's interesting how only the top 3 summers had over 20 90 degree days at JFK. EWR and JFK are actually a good match for summer weather, as the top summers in both are similar, I see 2010, 1983 and 2002 all in the top 10 list at EWR 1 2010 32 0 2 1983 26 0 3 2002 21 0

If we ever get a repeat of 2010 do you think we could break all time records? Wasn't 2010 following an 11 year cycle, so maybe every 11 years we would get a summer like that? If so the next one will be in 2032.

so much wild stuff in this list 1993: The Great Midwest Flood continued as flood waters came close the Des Moines, IA water treatment plant, leaving the city's 250,000 residents without water for 12 days. (Ref. Wilson Wx. History) was this great flood and our record heat both caused by the same thing in 1993? 1980: Hot weather prevailed from the southeast to the Plains. Daily records included: Wichita, KS: 111°, Columbia, MO: 108°, Dodge City, KS: 108°, Topeka, KS: 107°, DFW Airport, TX: 107°, Macon, GA: 104°, Savannah, GA: 103°, Memphis, TN: 103°, Houston, TX: 103°, Columbus, GA: 102°, Paducah, KY: 102°, Atlanta, GA: 101°, Chattanooga, TN: 100 °F. (Ref. Additional Temperatures Listed On This Link) persistent heat in 1980 continued 1912: Boston, MA recorded the end of the longest heat wave ever. It was 9 consecutive days with 90 °F or more. (Ref. NOAA Boston Weather Events) 1936: From July 5-17, temperatures exceeding 111 degrees in Manitoba and Ontario claimed 1,180 lives (mostly the elderly and infants) during the most prolonged, deadliest heat wave on record. Four hundred of these deaths were caused by people who drowned seeking refuge from the heat. In fact, the heat was so intense that steel rail lines and bridge girders twisted, sidewalks buckled, crops wilted and fruit baked on trees. Some record temperatures include; 112 degrees at St. Albans and Emerson, Manitoba, 111 at Brandon, Manitoba, 108 at Atikokan, Ontario, and Winnipeg, Manitoba. 1936: Unbelievable heat occurred across the Mid Atlantic states and the deadliest heat wave ever in parts of Canada. Ontario, Canada recorded its hottest temperature ever as the town of Atikokan hit 108°. On the same day in Manitoba, Winnipeg also reached 108°, the highest recorded temperature there since records began in the 1870's. St. Albans set Manitoba’s all-time record as they soared to 112°. In the United States, the all-time record high was set at Rochester, MN with 108°. Other daily record highs were set at Lincoln, NE: 109°; Peoria, IL: 108°; Rockford, IL: 108°, Grand Forks, ND: 108°, Decatur, IL: 107°, Moline, IL: 107°, Dubuque, IA: 107°, Minneapolis, MN: 106°, St. Cloud, MN: 106°, Fargo, ND: 106°, Springfield, IL: 105°, Champaign, IL: 105°, (Ref. Additional Temperatures Listed On This Link) wtf was going on in 1912 and 1936? Wasn't 1912 the year Fenway Park opened and the year the Titanic sank? and look at that heat in 1936, you'd think with all that dust in the air from the Dust Bowl, the heat would actually be less.

But we have not had record July heat, just a lot of cloud cover and stalled fronts.

damn that's really bad for your solar panels!!

Thanks for this extensive list Chris-- how is it possible that LGA did not record 100 degrees even one time in July 1993? EWR had 4 in a row, NYC had 3 in a row and JFK had 2 in a row in that month? I also agree about the monsoonal type pattern, it seems like our summers are becoming cloudier and we are getting many more in the way of stalled fronts in our area in July? This never used to happen before, has the Bermuda Ridge become too weak to hold fronts well back to our west as it used to do in summers like 1993, 1999 and 2010? Is there a way to specifically track amount of cloudiness for the month of July through the years and decades?

Something I wanted to ask you about-- since we have broken the June 100 degree barrier here on the south shore / JFK the next barrier that needs to be broken is getting a 100 degree day in September. It's never happened at JFK has it? And the last time that Central Park had a 100 degree day in September was on September 2, 1953? The only other time Central Park hit 100 degrees in September was September 8, 1881? A notable 99 was reached on September 11, 1983, which was our latest 99. I don't think JFK has hit 99 in September (though they have hit 98 a few times.) So our next goal should be to get to 100 in September.....

This doesn't look to be a high end hot summer on the scale of 1993 or 2010, but more like 1994, when we had early extreme heat and the rest of the summer was mediocre.
