Study finds lower emissions from higher-ethanol gasoline

California residents will soon get some price relief at the pump and reductions in harmful vehicle emissions, thanks in part to a landmark UC Riverside vehicle emissions study.

If you install two cat flaps in front of a 🐱litter box, you never know which flap the cat will enter and exit through. ▶️ ◀️

You also don't know whether the cat's droppings in the litter box will be #wavy 🌊 (liquid) or #particulate (solid) 💩

This makes cats wonderful study #animals if you want to #study #quantum #physics - or not! ⁉️

Mask up, NYC! Our air quality index is ORANGE; up to 130(!) - unhealthy (101-150) for sensitive groups! It's mostly not ozone, it's smoke particulate, I believe.

Hey, NYC, mask up! Unhealthy air quality today, all the way in the RED zone(!) - score of 151, just over the border.
(It's ozone, not smoke particulate, that's the main concern.)

Up in my corner of #Edmonton we have #AirQuality tonight over 200 using the #EPA system, primarily due to particulate from #WilfireSmoke.

Whilst breathing this sucks, at least it changes the light to a orange-ish tinge, like having almost-sunset daylong instead of around 22:00h.

L.A. County declares health emergency due to smoke and ash Smoke hovers over the L.A. Basin

“The fires, coupled with strong winds, have severely degraded air quality by releasing hazardous #smoke and #particulate matter, posing immediate and long-term risks to public #health,” the department said in a statement Friday evening.

Live updates: Winds prolong fire risk as investigators probe electrical tower as possible origin of Eaton fir

There have been at least 24 deaths and more than 12,000 structures damaged or destroyed in the L.A.-area fires. After a day of progress in containing the Eaton and Palisades fires, crews are bracing for several days of winds that could hamper efforts to contain the firestorms.

Los Angeles Times

#LAFire has spread across #SouthernCalifornia and #CBSNews LA footage shows victims who reveal surviving #AltaDena #fire by personally defending home, damping out flames even with no water, while neighbors abandoned, and one victim's lone structure is still standing on block due to his death defying diligence.

Even though not in path of documented blazes, areas like #LakeElsinore are without power due to safety concerns, and many communities are exposed to dangerous #particulate matter in air requiring #N95 NIOSH masks, conditions far worse than normal #SMOG.

Early estimates find total damage and economic loss due to the #LosAngeles #wildfires is already between $135 billion and $150 billion, with much more estimates to be defined in #NewYear

#Chevron says Richmond ballot measure to tax refinery will cost Bay Area drivers

By Cornell Barnard

"One of the Bay Area's largest refineries says it's against a tax measure on November's ballot, which could force it to pay more in taxes.

"Chevron is firing back at the City of Richmond, which greenlighted the measure. Chevron says if voters approve it, drivers across the Bay Area can expect to pay more at the pump.

"'This tax is the wrong approach,' said Tolly Graves, the director of Chevron's Richmond refinery, making it clear that the company is against a refinery tax, dubbed the '#PollutersPay Initiative.'

"In November, voters will decide to tax one of the state's largest refineries $1 for each barrel of oil processed in city limits.

"'At Chevron, our objective is always to provide reliable, affordable and clean [sic] energy to our customers and this tax puts all three at risk,' said Graves.

[...]

"Supporters of the tax argue that #pollution from the refinery has impacted residents' health.

"'The local air district traces the #particulate matter from the refinery. It's five-to-11 premature deaths every year,' said Kerry Guerlin, attorney from Communities for a Better Environment Action."
