Watching our California tides rise higher this year in real time. Today was supposed to be a no-biggie tide of about 6.3’, but it came in at 7.3’. A whole foot higher!

Unlike so many others, the @financialtimes.com nails the "OMG, 1.5℃ is gone" message: "Temperature overshoot requires urgent action" Yep. And every 0.01℃ matters. Reminds me of my NYT oped with @costasamaras.com: "The widely recited '12-year deadline' is wrong — and right." gwagner.com/12years
UN report: temperature overshoot requires urgent action to keep warming in line with Paris accordWith children, days might last forever, but years fly by. Something similar applies to climate policy. The current days of delay and debates can seem to drag on forever, but the next presidential election is right around the corner, and so is 2030.

These articles (and headlines) make me so frustrated because they ignore the fact that for about the past decade, cities/towns that seemed “safe” from wildfire have burned. We can have deep empathy and concern for Spokane without encouraging collective amnesia about what we are all living through.

This week’s anticipated smoke intrusion in the Bay Area may not be accompanied by the pungent campfire scent. That’s because of atmospheric chemical reactions that change the molecular makeup of smoke particles: It makes the plume more toxic as it ages, but removes the smoky scent.
