  • When it comes to extreme weather, heat can be a “silent killer.”
    As the climate warms, small changes in average temperature can have big impacts, including an increase in the number of people exposed to extreme heat.

    Heat almost killed me while roofing in the AZ summer. After vomiting everything, I went into convulsions until unconscious.
    If not for a plumber down below, I would have died. Wet towels and electrolytes brought me back. It took a week to recover. I then went to college and graduated to a white collar career. Don't mess with the heat. It wins out in the end.

      Scary story! I’m 25 years old still biking and skating around the Phoenix area to commute and I’m always worried about being low on electrolytes and water, unable to beat the heat.
      I had a seriously close call when I planned a trip across town poorly, became super dehydrated and abandoned my bicycle so I could take a shortcut through the desert so I could get home faster. A friendly neighbor let me drink from his hose and saved my life. I knocked on like 10 doors before someone answered.

      As a nurse living in the deep south I tell people that if they can't afford Gatorade or other sports drink, add a salt package to your water. You not only need water but electrolytes like magnesium and sodium. I tell people to drink 1 drink with electrolytes for every 3 to 4 bottles of water.
      If you are outside working and you notice your sweat isn't salty anymore, you need to seek shade and electrolytes real quick.
      I tell the elderly to take their temp every 2 hours during days when it's 90 to 95. Every hour for 95+ and they need the heat index, not just the temperature.

    So how does measuring heat better help us?
    Can we stop going to work? Can we stay home with the air conditioner?
    What if you don't have an air conditioner?
    You say this as if our society is going to chage in order to compensate the heat.

    Today, we are living in fairly cold conditions, and we may approching spring [earth sezon] in Galactic Year season temperatures. 😀 instead of putting the blame on ppl, they should stop sending uranium warheads to ukraine and investing money into technology research in preparation for not so freezing GY summer ahead. We are too little to be able to manipulate GY temperature and can protuce grate insulation if wanted.
    We can not change the Phanerozoic climate, but we can adapt to it.
