Are those regular dry bulb Temps? That doesn't really add to the conversation. The thing about wet bulb temp is that it measures the ability for water to drop temperature due to evaporative cooling. It is a defacto measure of the heat present in the air, as it takes a lot more actual heat (energy, not temperature) to raise the temperature of humid air than dry air.
Never before in my lifetime have we had successive days well above 100 and even 110 degrees like we had last year without it being related to excessive drought/extremely low humidity. With adequate rainfall in my area of South Texas, there are summers it has even failed to reach 100 degrees. Certainly, there was an extraordinary amount of moisture and heat in the air in my part of Texas last year. We have never had that much moisture and Temps over 100 degrees in my lifetime.
I have heard it was likely due to the 2022 Hunga Tonga volcano expelling like an extra 10% of water vapor into the atmosphere, and it will take multiple years for that to cool and precipitate out of the atmosphere. Unsure if that is still the theory or if it has been disproven.

I'm old. I work in the garden with a 110 heat index. Folks need to get out more.

No, just regular high temp data.

Sure it does. RC said last summer was unprecedented. I was showing that it wasn't.

Okay.

You should present the last summer's data with historical data to substantiate your feelings about last summer.

Nah. It was La Nina. It was forecast to be a hot summer before the summer and it was. The nice thing about La Nina is it kept the hurricanes away. La Nina allows high pressure systems to camp out over the northern Gulf and Southern U.S.
Currently La Nina is fading to neutral between La Nina and El Nino but La Nina is predicted to make a come back mid summer.
June will likely be normally warm/hot with July and August being hotter than normal for the southern U.S.

They also had a shorter life expectancy than current day along with having buildings designed to handle heat and cold differently than modern ones.

What does life expectancy have to do with the climate hysteria?

A lot of the people “susceptible” to climate change are ones that, historically, wouldn’t have lived this long.
Doesn’t mean the climate is actually changing, IMHO, as much as events which used to cause mass die offs at much younger ages no longer happen, so people are dying in other ways.
Kind of like cancer rates IMHO… life used to kill you long before you got cancer (infections, heart attacks, whatever). Improvements in medicine and nutrition means that people whose genes were wired for cancer now live long enough to have that actually express itself rather than dying much younger.

High Temps are "dry bulb" temps, not the wet bulb temperature we are talking about. You are essentially saying, "I'm right, and here's data measuring something else to prove it."
Again, water has a very high heat coefficient - it is very capable of storing heat energy (hot humid air) and removing it (sweat evaporating in dry air). Compounding this, the warmer the temperature, the more water vapor can be dissolved in the air (holding heat in the air) at the same relative humidity. Not only do you have to heat up the existing water vapor in the air from 99 to 100 degrees, to maintain the same relative humidity you have to add more water vapor to the air and heat that up as well. That is a knock on effect that makes a 95 degree WET bulb temperature very dangerous.
I think there are only a handful of counties/parishes in the US that have every recorded such a temperature. IIRC, Anahuac, Aransas and Cameron were the only in Texas, there were only a handful in Louisiana, and one or two in Florida. I'm not claiming we are at India levels of wet bulb temps, but last year was closer than any I have experienced.

they have lost their minds. send whoever wrote this trifling trash to NOLA or Biloxi for the summer.
their religion of politics creates homelessness in large cities.
there are several articles about the homeless illegal aliens in tent cities on a large grass strip near Brooklyn.
what will happen to these people after they are bused to vote in November?

when temperatures rise to 35C or more on the wet-bulb scale, coupled with very high humidity that prevents sweat from evaporating.
That’s 95 degrees. Come July 95 degrees feels good to me most days
These articles are nothing but fear porn. If it’s hot stay hydrated and don’t be out in the sun too long

That's not the same as a temperature of 95 degrees. I think y'all fundamentally don't understand what a wet bulb temp is.
For you to have a 95 degree wet bulb temp at 95 degrees dry bulb, you would have to be in a sauna with 95 degree water vapor and 100% humidity. It is not just a measurement of ambient temperature with a thermometer. You cover the end of a thermometer with a fabric cover, wet it with water at ambient temperature, and then spin it in the air from a string so that the water can evaporate in the air if able to do so.
You then compare the wet bulb temp vs. the dry bulb temp, look on a chart, and determine the relative humidity. The only way wet and dry bulb temps are the same is if you have 100% humidity.

Well, i'm pretty sure we all know the obvious answer. Clearly, increasing taxes on the middle class is the only way we can correct the planet's wobble.
