It’s official, red alerts have gone out across the entire country of Brazil as the heat index hits 137F. The high temperature combined with humidity has made it impossible for most people to carry out their normal lives. There’s already reports of power outages. People can’t work. They can’t run errands. They can barely sleep. It’s not even summer there yet.

I think what matters here is that the humidity makes this a wet bulb or something similar to a wet bulb instead of actually an oven. It’s super doom but it’s a slightly different and honestly worse kind.
Today’s high temp and humidity in Rio gives them a Wet Bulb Globe Temperature of 77⁰F, which is not great. WBGT of 80⁰-90⁰F is the danger zone, and recent research has suggested that WBGT 85⁰ is probably a more realistic upper limit of human safety.

They have clearly linked their source as BBC. Also, pretty much all major publications have reported on it. Here’s a report by AP: https://apnews.com/article/brazil-heat-wave-climate-environment-wildfires-1e4714fb2c6566120c13cf4e2b657f7d
We definitely are! It’s been a week since I got some sleep … It’s been 37°C to 40°C every day in my city and most people don’t even have AC… I don’t…
Which is also already deadly.
