Climate Change/Global Warming [On Topic]

[SkyDekker 1,465]

In the early 1980s, the continental United States required AC for 61 days, or about 66 percent of July through September. Now about 71 percent of summer days require AC. By 2060, the number of AC-required summer days is projected to rise even more, to reach 87 percent.

But when the grid gets overloaded from all the new A/Cs, and all the existing A/Cs running for much longer, I am sure the right will blame EVs, wind turbines and Biden - in that order.

Heck you might even see people buying old crappy EVs just so they CAN run A/C when it's super hot out.

F'n enough. I told you that's my plan and you aren't helping by spurring interest and running up the price. Maybe go back to bribing convenience store clerks or trading double dime bags for electrons in the hood.

Surely the right will blame Obama before any white guy.

More record heat into next week.  Vegas continues to break temperature records.  Houston about to swelter while thousands are still without A/C on account of Beryl.

Just normal weather, no trends here.

Yep.  Vegas hit 120 degrees for the first time; the old record was 117.  I hesitate to imagine what's it's like in Baker, CA, which is traditionally 5-10F hotter than Vegas.

In Henderson (right outside Las Vegas) they are having to close the public pools because the water is now dangerously hot.  So add "refrigeration of pool water" to the technologies we will need to fight climate change.

Road trip!  Please post pics. Why are you keeping track and why are you driving there? It sounds like a sentence from a judge not something a  sane person would do.

Being a moderator on here for some 20+ years gives you the impression of sanity? :)

That's why we went a month ago.  It was a whole 12 degrees cooler.  Win!

In an attempt to keep this on track out of consideration of Bigun, been reading about how this heat affects people's lives there - mainly because these problems will soon spread to other areas.

One issue is that in Henderson they had to close all the pools because the water was dangerously hot.  Does this mean pools simply closed when it's hot out?  Or pool refrigeration systems?

Another, coming from a pet owner's group in Vegas, is that people can't walk their dogs any more.  The streets are too hot during the day, and even at midnight someone recorded sidewalk temperatures over 120 (air temp was 105 at the time.)  At night the low temperatures were getting down to 95F, so some owners were getting up at 4am so they could walk their dogs when the sidewalks had cooled down enough.  But even 95F air temperature is tough on some dogs.

It will be interesting to see all the small and large changes in people's behavior due to warming.  "No more dogs in some areas" is one of the more minor ones.  But public pools is a bigger one IMO - some people rely on pools to keep themselves cool in the summer.  The future may see more high temperature shelters for people who can't afford A/C (or a home at all) in such areas.

I'm just an insensitive boor and an enemy of man's best friend, I guess, but I think anyone with a dog in the desert heat is as condemnable as those who leave them in a car on a hot day. Maybe, at least, people are keeping their cats inside and out of trouble.

Another tornado warning for the city of Chicago (and surrounding areas).  Apparently several have been sighted coming this way.

Until this year I don't recall any *warnings* in the city itself before (we had a few watches). I think this is the third or fourth this year.

Sirens going off.

Time to head for the basement.

I would really be interested in any peer reviewed studies demonstrating a link between climate change and an increase in the number or severity of tornadoes.

The line of storms split just before it got to us, with one part going north and the other south**.  We just got a few sprinkles.  Tornado touched down at O'Hare, and the NWS says maybe there were 10 altogether in the Chicago area.  Almost unprecedented.

 

** this happens a lot, we live just west of the extreme southern tip of Lake Michigan and I think the north/south temperature contast leads to a micro-climate that steers storms north or south of us, often just by a few miles.

@BIGUN you've misattributed the quote in your post to me - I didn't say that.

Last night a friend in Syracuse IN texted me that he was hearing warning sirens as he was heading for bed. One more text came in after that: "Power out".

That paper talks about one of the central issues of storm intensity - CAPE (convective available potential energy.)  It is the amount of bouyancy that a given section of atmosphere gives to a rising volume of moist air.  The stronger the CAPE, the faster it will rise and the more it will rise, leading to more intense storms.

Over water, climate change drives increased CAPE, because the stratosphere is cooler, and a cooler stratosphere means more available potential energy.  It is absolutely a factor when storms reach 50,000 feet (i.e. very big storms) which is why the conclusion that global warming will lead to more intense large storms is strong.  It is less strong for smaller storms, since in a well mixed atmosphere you won't see as much increase in differential at lower altitudes.

Over land the same effect occurs, but there may also be a stronger CIN (convective inhibition effect) due to the ground being potentially drier - higher ground temperatures dry out land more quickly, leaving less water available to create a volume of moist air necessary for storm initiation.  But each individual storm will generally be larger, so for a short time afterwards there will be MORE energy available.  Which is why the conclusion there isn't as strong.

Understand. Thank you.

A rare Sudden Stratospheric Warming (SSW) event has been detected in the stratosphere above the Antarctic region over the past week. Forecast models predict it will start to filter down through the atmosphere later this month.

https://watchers.news/2024/07/15/rare-sudden-stratospheric-warming-event-detected-over-antarctica/

These disturbances influence the geomagnetic activity of Earth’s atmosphere, with changes detectable and measurable.

The NWS has confirmed 11 tornados from Monday's storm.

[kallend 2,026]

Now NWS says there were 19 tornados in the Chicago area on Monday.

Climate changes. It always has. That the crisis is caused by, or can be controlled by humans, is a scam. Don't be scammed. Do some serious research, especially non-climate scientists.

Yep.  We are just forcing it to change far faster than it has in the past 100,000 years or so.

We know for a fact that we are increasing CO2 concentrations through burning fossil fuels.  We know for a fact that CO2 is a greenhouse gas.  We know for a fact that increases in temperature have been closely correlated to CO2 increases.  And we know it's not the sun because the stratosphere is cooling. 

Sorry about the facts.
