We're Havin' a Heat Wave

Most of you have probably been following the weather reports. Being an Arizonan, we've been paying close attention to the record-setting temps in California, Nevada, and Arizona. Heat kills more people in the United States than any other type of weather. Hot car deaths are a consistent problem
but it's not just the heat, it's the humidity. The heat index, a measure that combines the air's temperature and moisture content, essentially indicates what it will feel like when you step outside. The compounding effects of increasing temperature and humidity can be exceptionally dangerous.

Planes are grounded, tap water comes out hot, and we’d all better get used to it.
In the Arizona desert, as far back as weather records go, it's never been this hot for this long.

By early Monday afternoon, the temperature was 111 degrees in Tucson, the first in a forecasted series of a record-setting seven consecutive days with highs above 110, the longest streak in city history. (The previous record, should it fall, was six days in a row in 1994.)
In Phoenix, just to the north, temperatures were even hotter. Meteorologists there are expecting temperatures to run as high as 120 degrees on Tuesday and Wednesday, at the apex of the heat wave. The National Weather Service is calling the heat wave "extreme even by desert standards."

The atmospheric culprit for the heat is a very intense high pressure, which is itself setting records. Though the statistical databases show this high of high pressure to be an approximately one-in-200-year event, these events have been occurring more often lately—with the last one happening just last year. In short, the background signal of global warming makes the entire atmosphere thinner and less dense, supporting stronger high-pressure centers like the one camped out over Arizona this week, which then tend to get stuck in place—cranking up the thermostat over a multi-state region.

Heat waves like this are quickly becoming the surest symptom of humanity's growing influence on the atmosphere. In Tucson, hot days are getting more common, with more than three weeks of additional days spent at 100 degrees or higher since 1980. The warming influence of more roads and parking lots matters, with urban areas warming faster than rural areas over the past few decades, but cities like Tucson and Phoenix are working on mitigating that effect through efforts like expanding urban forestry and installing more light-colored roofs.

If the power grid ever goes down Arizona/Utah/New Mexico/Nevada would be the last place I would want to be.

Not natural for so many humans to live in a waste land with such a large consumption of natural resources from other states to survive.

Sooner or later it will bite them in the ass.

Well, all that paving with asphalt increases heat, all the concrete that absorbs heat and keeps nighttime temps warmer, all that AC dumping heat into the surrounding air, and it is the desert, and people wonder why it gets hot.

Funny too was the sudden story about a few flights getting canceled because certain airplanes cannot operate safely above 117º. Only it happens most years, but we never got those stories going national until now. LOL

I'm reminded again of a story about the Southwest some years back that mentioned Phoenix itself, only had a population of 50,000 at the end of WWII. The vast majority who live there now are migrants or 2nd or 3rd generation migrants who moved away from the Rustbelt and other places in the east. That explains why, whenever I've driven through Vegas and other cities in the desert, they look surreal or ridiculous! Aside from tiled roofs, there's almost no concessions to living in a hot, dry climate!

Thanks to the Hoover Dam, sucking all the water out of the Colorado and Oglala Aquifer, millions of people have just transplanted the suburban life of cooler, wetter regions right into the middle of a desert! A shoutout needs to be given to the air conditioner, cause without that tech innovation, few would tolerate it...dry heat or not!

On that note, it has to be added that climatologists have been predicting for at least 20 years that the Southwest was undergoing a long term climate shift back to desert conditions that existed for centuries prior to the 1820's. Americans wouldn't have even wanted to try to move into Mexican territory that was really run by the Comanches until waves of farmers and ranchers started moving out and taking advantage of the change in precipitation levels. The climate shift that caused this drying out also ended the Anasazi Civilization that had become dependent on growing corn, squash and beans and had to abandon most of their cliff-side mud brick homes...with a few occupied by Hopi and others....anyway, I think the point is that in previous times people moving in to a desert, had to deal with the conditions as they existed/not drill down and drain aquifers...which the depleting of the Oglala is going to be a huge crisis for millions + agribusiness in a few decades.

It'd be nice if articles like the Pacific Standard piece would place the gradual global warming trend in context of other ongoing shifts in climate...but they never do! The final word is people living in Arizona, Nevada, New Mexico, West Texas and southern Cali are going to have to do a lot more than throw up a few windmills and solar panels if they are thinking of staying put.

Sound awful, Clara.
It's hot here on the East Coast, too - but not that hot.
I hate the heat. I won't spend more time in it than it takes to walk from the house to the car.
I live in air conditioning. LOL
Thanks from Clara007

Thanks, Tris. it's amazing how it's not a problem until someone else's state/city is hit by the same heat wave, blizzard, hurricane or earthquake. AND that will happen. Generally, some of these weather issues move across the nation.

Heat is extremely dangerous.

I'd be interested in seeing your source for "it happens most years", referring to flights being cancelled due to extreme heat.

Please post your source.
Thanks from RNG
