Climate - truthful information about climate, related activism and politics.

The heat stress also makes CVD worse, for similar reasons.

We'll probably learn about it from the Excess Death stats, but that also needs to be disentangled from the ongoing COVID-19 pandemic.

BTW it is a question of time not if, but when the electric grid in an Eastern European or Mediterranean country fails and this can cause far more deaths - I speak of hundreds of thousands - if it hits people depending on air conditioning. A big power failure in Italy or Greece and people would be fried alive.

This is also why we need solar power, it is far better matched to that peak demand. (Plus it kills fossil electricity by undercutting it in cost, which is a nice-to-have since we are at war with fossil power now - either we kill it, or it will kill us).

Tips from the US southwest for anyone not used to the heat, if you’d like them:

• Drink a stupid amount of water and eat salty stuff, as long as you don’t have a kidney condition
• If it’s a dry heat (<50% humidity) you can rapidly cool yourself with a wet washcloth or spray bottle and a fan. You’ll have to keep wetting it as it evaporates, but it works
• If it’s not a dry heat or you’re too hot for the washcloth thing, squeeze a cold pack under your arms or between your legs, the blood flow there will help you drop heat faster
• If you’re so hot that’s not helping, take a cool shower
• At night when it cools down, turn your AC as low as it will go/as low as finances allow. Every object in your house can ‘hold on’ to the cold and help cool your house during the day, the same way a full fridge maintains temperature better than an empty one
• Go to public places with AC if there are any near you (libraries and malls usually have AC here)
• Being unable to cool down no matter what you do is a MEDICAL EMERGENCY and you should treat it that way! Heat exhaustion and heat stroke are serious and have lifelong consequences

If you already know all this and are still suffering, I feel you. Our turn is coming 😩

as some one who lived and worked outdoors in tropical north Austalia for 45 years, before moving much closer to the south pole, i left when i needed AC as it was getting too hot and humad.

I used to visit social centres like the library and use their AC and WiFi or just read a book on the real killer, hot days. or go swimming :)

Good home insulation makes a difference but can only hold the worst of it off.

As to making it worse, the same thing with cars, plane flights etc and not voting Greens to eneact policy change. Just have to look around to see most people are making it worse with enthusiasm every day, they just feel no guilt :)
