Classic summer conditions. I bet the pools are packed. America was also built with forced labor, so I’m not sure referencing how America was built in the past helps the idea that construction workers don’t need AC. As we move into the age of new “normal” it will only become more needed, so might as well invest now. 1 1 Link to comment Share on other sites More sharing options...

Paleocene Posted June 22 Share Posted June 22 EPA regs and the decline of coal power are huge. I also think, but haven't seen good quantification yet (please link me if you have it) that we're really benefitting from two additional things in this decade. One, the rapidly increasing share of solar and other renewable power. Two, increasing share of hybrids and EVs in the aggregate vehicle fleet. Hopefully we can eventually clean up all the small engine crap out there too. I was born in the 80s and remember the 90s-early 00s haze and hope we never go back! 2 Link to comment Share on other sites More sharing options...

I'm impressed they were doing work in the beating sun with no visible cooling stations around. i just simply try to avoid driving anywhere in the DMV if at all possible. 1 Link to comment Share on other sites More sharing options...

North America has made incredible strides in cleaner air thanks to legislative action that some would trash today. The air quality in many other parts of the world is horrendous. 4 Link to comment Share on other sites More sharing options...

87storms Posted June 22 Share Posted June 22 I was just thinking about the lack of hhh this week. I definitely remember more of those in the 90s. Granted, we have plenty of other issues to address, but air quality does seem to have improved. 1 Link to comment Share on other sites More sharing options...
MN Transplant Posted June 22 Share Posted June 22 14 hours ago, MN Transplant said: 17.4C on the morning sounding at IAD. The models diverge by 00z this evening, with the GFS already pushing 20 and the NAM stuck in the 18 range. I can't fathom that the NAM will be correct here. 19.4, so somewhere in the middle.

CAPE Posted June 22 Share Posted June 22 11 hours ago, LongRanger said: The down side is clean air lets in more light, which means more global warming.https://skepticalscience.com/global-cooling-mid-20th-century-advanced.htm There is an ongoing discussion/debate associated with the international requirements for reduced emissions from ships having an impact on warming. I work for the shipping industry on the training side, and we constantly adapt our course offerings to any (new) international requirements. Currently many ships powered by 2 stroke diesels are switching over to burning LNG as a fuel because its 'cleaner'. These engines are considered dual fuel- burning diesel as a back up to the boil off gas from the LNG. Pretty complex process from storage of the fuel as a cryogenic liquid to getting it to an acceptable pressure and temperature where it can be injected into the engine. The article linked below references a UMBC study on warming effects related to reduced SO2 emissions. Quote The study adds to an ongoing debate among climate scientists about the consequences of an International Maritime Organization (IMO) rule that slashed the amount of sulphur dioxide pollution in shipping emissions after 2020. That added air pollution from burning heavy marine fuel was linked to tens of thousands of deaths each year. However, those aerosols also had a cooling effect on the climate by reflecting solar radiation directly as well as through their brightening influence on clouds over the ocean. Researchers expected that slashing those emissions would result in some warming due to the loss of sulphur dioxide’s cooling effects. But the magnitude of anticipated warming ranged widely. Yuan and his colleagues have now estimated the warming effect of the 2020 rule using satellite observations of cloud conditions, along with mathematical models of how clouds might change in response to the expected reduction in sulphur aerosols. The researchers calculate the drop increased the amount of solar energy heating the oceans by between 0.1 and 0.3 watts per square metre, around double that of some earlier estimates. This effect was more acute in areas of the ocean with lots of shipping activity: the North Atlantic, which has been anomalously hot since last year, experienced a warming influence more than triple the average, according to the study. https://www.newscientist.com/article/2433564-cleaner-ship-emissions-may-warm-the-planet-far-faster-than-expected/#:~:text=This effect was more acute,average%2C according to the study. 3 1 Link to comment Share on other sites More sharing options...

dailylurker Posted June 22 Share Posted June 22 It noticed it's much more humid outside this morning than it has been this season. I noticed less dew on my plants though. Today should be an epic pool day for kids. I remember Saturdays like this. Brutally hot swim meet that lasted until around 1. Then fun at the pool for the rest of the day. 2 Link to comment Share on other sites More sharing options...

Thought you woulda hit 90 by now. “Heat dome” has now surpassed “base state” as the most overused met term. Let’s hope someone breaks the century mark after hearing about the heat (endlessly) to make this bout at least noteworthy. 2 Link to comment Share on other sites More sharing options...

kgottwald Posted June 22 Share Posted June 22 The first time I ever saw blue skies and puffy clouds on a hot, humid day was in August 1988, during the record string of 90-degree days. Bill Kamal on channel 9 commented on how unusual it was, that the air came straight from the tropics. 1 Link to comment Share on other sites More sharing options...

I think there's a rule against questioning any weatherman who posts such a good Heat Miser picture. I figure Mr. Tony P carries it around in his wallet. Sort of related to the ref's red card.
