It's hot. Temperature is at or near an all-time high.

But also, the sun feels a lot stronger! You can feel your skin starting to burn in a couple of minutes. That's new.

Is the air cleaner than it used to be? Is the sun at a maximum in its cycle? I don't know but the difference is startling.

If this is only the beginning of an upwards trend in the coming years, there's going to be big issues...
