I agree with you Zip that firefighters ability to rescue people or fight fires in temps like this, is absolutely amazing, and their willingness to do it, is absolutely admirable.
I saw a clip on the local news of the hikers rescued off the Bump and Grind. They were two fairly fit looking women in their sixties--by no means were they overweight or obviously out of shape. If they called for a rescue at 9 am they must have begun at, I'm guessing, maybe 8 or 8.30. For much of the year that's reasonable, and most people don't imagine it can be 104 at 9 am (which is what it was.) Of course, they should have started no later than 6.30, and even that, on a day like today, is a late start. So while they miscalculated badly, I'm inclined to cut them some slack. Also, Palm Desert seems to have been unusually and especially hot--it was a couple of degrees hotter there today than even in Thermal, usually our hottest spot. So the microclimate on Bump and Grind (barren and exposed) may have made it even hotter than could have been anticipated.
They had a guy on the KESQ news going around getting readings from various surfaces in the valley--the temperature of the ground (gravel surface) was 179 degrees.

My AC actually stopped working for several hours today--the repair guy came out and said nothing was wrong with it, it just stops working when temps are this high because the condenser overheats.
Somebody just wake me up in November.
