Looks like Needles and Death Valley were the only ones to exceed 120 so far.

must be difficult for planes to take off in that weather

wow and JFK hit 100 both those years....94 in 1972 when JFK hit 100 must've been one of the largest gaps of temp between the two with JFK hitting 100.

we've been very slow to change because of a "wait and see" approach that just means the changes that need to be made will have to be made on a faster trajectory. The fact is the changes to our climate are no longer theoretical, they are very tangible now. Megadrought in the west along with massive expansion of forest fires, much higher humidity and rainfall in the southeast and midatlantic regions including the NYC area. Tangible rises in sea level that has lead to a rapid increase in sunny day flooding, in cities like Miami and Charleston. Evacuations of residents being made off barrier islands off the Lousiana coast because sea level rise has made those islands uninhabitable. Climate change causing the death of food crops in Central America resulting in mass migrations north. Much more soon to follow.

I see some amazing things going on in California https://twitter.com/i/events/1404519631667216389 It has the best economy of any state by far and is already 21% powered by solar energy!

wow interesting, all the wet was along the coast.....and to my knowledge there weren't even any tropical cyclones for us that year.

I wonder what the heck happened in 1983 to set all those heat records at the same time as having the wettest year on record lol (it was JFK's wettest year on record too?) Thanks for the list, those are some of my favorite summers! 1983 had 2 100 degree days at JFK and just 1 at NYC?

wow how often does Medicine Hat reach 100? I'm familiar with the region from Calgary to Medicine Hat to Brooks to Red Deer up to Edmonton, can't say I've seen it reach 100 there much.

with better education and lessening the influences of religion one would hope that population growth tapers off on its own.

Yep, we see that in other industries too, like bio and chemical engineering.

That would be amazing but wont there be some lag before we can get CO2 levels to come down?

Don do you think Phoenix could hit 120 during this torrid stretch?

Any changes we make towards renewable energy will be too late to change anything for the next century or so. We're going to have to go full tilt towards climate modification, and part of that means redistributing rainfall from the east to the west. Whatever the cost is, it must be done. We do plenty of engineering in the other sciences, weather should not be off limits.

How much energy would it take for us to engineer the Hadley Cell? We will need weather and climate modification to make it to the next century.

We may have to start weather engineering. Weather science should not be offlimits, we tinker with nature in every other science, why not weather too?

Once Lake Mead dries up, several states will be in trouble. 30 years at the latest.

Thanks this is more like it! A lot of my favorite summers are in the high temp list. 2010 is still lapping the field though like Secretariat at the Belmont lol. I wonder if those 90 and 95 and 100 day numbers from 2010 will ever be exceeded? Look at how 2010 and 1983 are both miles ahead of the rest of the field for 90 degree highs, but 2010 puts some distance between it and 1983 even so..... Do you also have a list of most 95+ and 100+ days for JFK too, Chris?

I view average temperatures as highly suspect as warmer mins do not impress me (how much of that is the concretization of our cities?) so I go by number of hot days (90 degrees or higher), and I specifically refer to JFK as that is closest to my location....they set the record in 2010 for both most number of 90 and 95 degree highs, I think they had 3 100 degree highs, which is 1 behind 1966. 1980 and 1983 were both amazing in terms of sustained heat. I think the summers I'd want to experience again would be 1980, 1983, 1991, 1993, 2002 and 2010. I wasn't born in time for 1966, but I'd love to experience that one too. And the winter that followed also!

without humidity it's pretty good. 100 degrees and low humidity is great weather to run in even here. Once it gets above 110 I dont like it so much.

and we must remember this 11 year hot cycle covered the entire continent, so the drought and heat in the west and even the midwest could be the start of a coast to coast megaheatwave.

I thought 2010 was pretty amazing for JFK, because it's the only one that had 30+ 90 degree days there (31) and they also had 10+ 95+ degree days (11)! Three days out of four around July 4th weekend were above 100 there! I wonder if that'll ever happen again? It almost seems like the 1995-96 of summers. 1993 had that torrid heatwave after July 4th weekend, I don't know why it seems so much worse than 2010 just for that particular heat wave. Maybe because that was the last summer I went without AC? Do you remember it- even JFK had two days above 100 degrees in a row, while NYC had three, and EWR had an astounding 5 (including two in that stretch that reached 105!) I think EWR finished with an amazing 9 100+ degree days! Do you think they could ever get 10 of those days? Going back to 1980, I remember that was the first heatwave that I analyzed. We had an 80 degree average for 2 months- July and August! That was pretty amazing. I remember reading that hundreds of people died in St Louis- not so amazing. But the heatwave covered the country from the third week of June through the third week of September, so pretty much the entire summer. 1983 had one of the hottest three month averages I'd seen, and with the record rainfall, it also had one of the most humid summers we've ever had. On top of that temps were still hitting 99 in September and still in the mid 90s as late as the equinox and a few days after!

Right, also a quicker storm than what 1888 was. We had a foot of snow after an inch of rain which was the first time thats happened. March 1888 was also rain at the start but the storm lasted so long that over 2 feet of snow fell on the backend. Imagine that- over 2 feet of backside snow!

The thing I find odd is that so few of the high 90 degree summers are on this list. Just off the top of my head I would've thought 1966, 1980, 1983, 1991, and 1993 should be near the top.

Yep, the differences are stark. Manhattan actually has trees and I think the buildings being close together provide some shade. The temps really ramp up as soon as I get into Queens but they start falling fairly rapidly again past that park with the lake in it that's near the GCP.

I just find it really hard to believe that 2020 was anywhere near as hot as 2010 was, you can see that with how few its 90 degree highs are compared to 2010. The other thing is I always notice a significant bump up in temps after I leave Manhattan and drive into Queens through the Midtown tunnel. The temps in that area are higher than they are in any other part of the city. From about the part of Queens right outside the Midtown tunnel through about the Grand Central Parkway. There's some park with a lake in it just off the GCP and after that point, the temps start dropping again.
