Greta Thunberg and Ponder the Maunder

This was cute:

The point I just want to add is that I don't recall anything like the same vitriol, and none of the expressed desire to slap her or spank her, against that Ponder the Maunder girl from years back, a teenager whose father convinced her that she had refuted all of climate science. My recollection is that girl eventually reached the point in college where Greta is right now, telling people to listen to scientists (can't seem to find a link tho).

Just another indication of who's arguing based on reason and who's relying on emotion.

The long-awaited Bay Area gas station count is here - more hints of an EV effect making ICE vehicles less convenient

Don't get too excited now. Updated figures on gas stations and gasoline consumption in the Bay Area are out:

Gas stations continue to decrease despite a strong economy and an increased population. San Francisco in particular lost 14% of its gas stations in a year, and now has one station for every 11,000 people. While many other factors could influence gas station counts, there's also gas consumption:

Consumption is down 7% from the high in 2016, mirroring the decrease in gas stations since 2016.

It takes a while for the increasing market share of new EV purchases to be reflected by the total vehicle fleet. OTOH, EVs get driven more than ICE vehicles so their share of vehicle miles will be greater than the share of the total fleet. It seems likely that EV market penetration is a big part of the reason gas consumption is decreasing and part of the reason why stations are disappearing. As EVs become more convenient, ICE vehicles are becoming less convenient to fill up.

Eli Explains It All: Amazon and Oxygen Edition

Eli, as readers of this blog know, often explains it all,  often belatedly, but allow the Bunny to put to rest your fears that burning in the Amazon will deplete oxygen in the atmosphere.

The concentration of CO2 in the atmosphere is ~400 ppm.  Oxygen is approximately 20%.  That translates out to 200,000 ppm. If CO2 doubles to 800 ppm that would at worst put O2 at 199,600 ppm. 

It's as simple as that, but if you insist on long reads, have at it.
