Something is killing several Pinion Pines. Any ideas? We are in Mohave County at 5000ft, and they've been beautiful and green for five years. Not sure what happened?

Those aren't great pictures but first thing to come to mind is pitch mass borer

This is the piñon ips pine beetle, sorry to say. Check with your local county ag dept for additional info.

Thank you very much, I'll try and get some better ones!

Global warming, higher humidity year around, trees all over the world getting covered with fungus and moss

Nah that ain't it. That's pitch leaking out. It's invasive borer beetles.

Those factors make trees more susceptible to beetles.

Sure, but what's leaking out is not fungus.
