You'd think he'd be happier having mastered science and having the whole world figured out in his early 20's.

The Emigrant Fire in the central Oregon Cascades has burned over 6000 acres at this point in an area that has received record or near-record low precipitation since April 1st this year (based on 45 years of data), as shown by nearby SNOTEL stations.

Well, here's a live look at the situation, the Emigrant Fire.

The Emigrant Fire in the central Oregon Cascades is unfortunately growing rapidly and is now sprouting a broad pyrocumulus cloud, as seen from the Univ of Oregon Wildfire camera placed on Peak 2 of Willamette Pass ski resort.

Our dew point in Eugene OR also hit 60 a little bit ago. This is actually a good thing since we had an early morning mostly dry but localized lightning storm which seems to have ignited several fires. :(

It's cool that boundary layer ventilation can go both ways!

Thank you for your attention to this matter.

You've had them on leash this whole time?!

Yikes, I tried it with ChatGPT and got something different but similarly very wrong.

The package came in a brown box and a brown van, what do you mean we have to pay?!

Just had a helicopter with a water bucket fly over my house in south Eugene (Oregon), very likely out to the new fire just east of Oakridge.

Maybe Vance is trying to vigorously couch their public statement?

Fragile, easily scrambled, and somehow always stuck to things they weren’t meant to be. It checks out.

You're right that altitude does affect oxygen density, but it's because of the dependence of pressure on altitude. It's really the pressure that is key (via Dalton's Law of Partial Pressures also with a dependence on temperature via the ideal gas law).

Larry O'Neill @larryoneill.bsky.social · Aug 6

The density of oxygen is constant on a pressure surface regardless of its altitude.

Ha! If true, I'll need to restock my red string supply.

There's been a big uptick lately in the messages I've received about people frightened about clouds and contrails.
