In how long???

The earth just broke the record for the hottest day in 120,000 years. In fact, we broke in on three separate days.

National climate emergency now.

The chick is a piece of work.

I would like to see a study on official temperature recording stations and their locality to "heat" islands (cities, airports etc.). I assume the number of "heat" islands has increased (more pavement), while the recording stations have remained in the same localities.

What the f is wet bulb?
I'm not positive, but I have seem someone wrap a wet cloth around a special thermometer tied to a rope not much bigger than string and then holding on to the rope swing the thermometer around quickly in the air in circles of about four to six feet long. He would keep that up for a minute, then stop and read the temperature on the bulb.

You described a DYI sling psychrometer. Video shows a cheap commercially available version and how it's used.
