Yes actually in some places it lowers the chances of big heat since it affects mins much more than it affects maxes plus more rainfall makes it much harder to have record heat in the summer here.

I just learned that the latest it ever hit 100 in NYC was on September 7th at 101, it was also the earliest it ever hit 100 in NYC because it happened in 1881 lol. We all believe in climate change but it doesn't affect every location in the same way and not all times of the year are affected in the same way either and it affects maxes and mins differently too. It's a much more complex issue than a +1.5 C rise across the board.

I was alive when this historic heatwave happened and I remember Craig Allen said it was 5.... was 7-11-1993 adjusted downward to 99? Back then Craig Allen said the high was 102 on that date, while it was 97 at NYC. The weird thing is I remember the total number of 100+ days as 9 so if one was taken away, another one must have been added later that summer to make the total unchanged. At any rate the magnitude of the heat in July 1993 was much higher than it was in 2022, most of those days barely touched 100.

-4 1993-07-07 through 1993-07-10 This can't be right, there were 5 consecutive days of 100+ at Newark in July 1993, and 3 consecutive days of 100+ at NYC and 2 consecutive days of 100+ at JFK (which is why the heat was of far greater magnitude than anything we have had since then. These three were our most historic heatwaves: 4 2010-07-04 through 2010-07-07 - 4 1993-07-07 through 1993-07-10 - 4 1953-08-28 through 1953-08-31 3 3 2011-07-21 through 2011-07-23

The all-time record for any month was 5 days in a row in July 2022. No Chris, it was in July 1993 when it was hot enough for the entire metro area to be above 100 and Newark had 5 days of 100+ in a row and 9 total.

hopefully the sea breeze is out by the hamptons where it belongs

Yes, I put it on the north side to keep it as far away from sunlight as possible, but it still recorded 93.7 last Thursday so I used the average of all four sensors (90.0 to 93.7) and came up with a high of 92 for that day.

Yes, and I've noticed it's a cascading effect because besides CO2 we also have more methane and more water vapor (all three are greenhouse gasses), we are becoming cloudier by the year which is increasing the impact, just like it did with Venus (even though its clouds have a different composition, mostly sulfuric acid.)

we need to look at some of these other sensors to see if they have any exposure to the sun and are properly sited too.

Humans have now reached the point where it's a runaway greenhouse effect. I remember there was an article posted that we are on the pathway to a similar fate as what happened to Venus.

Nice, I think we started exceeding that in the 1990s. I remember at the time that 1990 and 1991 were the two hottest years on record (both locally with 23 of 24 months above normal at NYC and globally with the hottest years on record up to that point.) If I remember what I read back then correctly, we jumped to a global mean temperature in the 57 degree range.

Yes, we've passed the point of benefits, which I believe ended in the 1990s. But the ice ages and the cold we had in the 1800s wasn't the ideal climate for humans either.

also, for farming purposes maybe a halfway point was better. Definitely not the ice ages and definitely not what we have now. I'd estimate that our ideal climate for productivity and food growth was somewhere between the 1950s and the 1990s, we went downhill rapidly after that.

You can also argue that at least some of the warming has had a beneficial impact on humanity.

we're going to need that to get everyone to join the 100+ party

Yes this is what I was thinking!! heat+dryness

now thats hot!!

no idea but it might be a combination of heat + dryness

what about the burnt fields of cotton?

if you're talking about air conditioning the combo with the higher humidity is probably worse because of how they work (condensation systems) 2010 with 101 degrees and 45 dew point was much easier to handle than 2019 which had 99 degrees and a heat index of 117 (I forgot what the dew point was those 2 weekend days.)

Both are bad, we need the dew points in the 50s or lower, regardless of the temperature.

this reminds of coastal huggers that make it rain at the coast while it snows inland. That is what this kind of heat reminds me of.

2002 I agree with but not 1988 we had much more backdoor fronting going on in 1988. It was hot no doubt but not on the level of the summers at the top (1993, 2010, etc.) We need a way to measure heatwaves the way we measure KU, coverage counts with KU events too. Thats why the top two events are March 1993 and January 1996.

but we don't know how reliable those thermometers are or if they meet NWS criteria, it's like reading snowfall reports from a PNS. Plus for the heat to actually be historic it should cover more of the area like it did in 2010 and 2011.

it's not just a local thing, and NYC makes the list too. I'm not convinced this is just about the sea breeze either, as our heat was much more prolonged in the 1940s and 1950s. CC has blunted extreme summer heat in our area, lowering the number of extreme heat waves (7+ days in a row over 90).
