I'm feeling frustrated that taking a bikeride in the late afternoon in SF Westside leaves me more stressed. And sad that we're talking about taking away rather than adding #SlowStreets. We have @JFKPromenade and @GreatWalkway -- for now -- but that still requires me to bike through the gauntlet of angry cars in OMI, Sunset, and Forest Hill to get there.

So does reopening the #GreatWalkway to 🚘 have a climate impact? We can calculate that using the @NCST_Research induced travel calculator travelcalculator.ncst.ucdavis.edu. 🧵 Adding 2 mi x 4 lanes = 8 lane-mi of class 3 roadway in SF (if fully reopened) would mean 21 million more vehicle miles traveled each year.

Estimating 0.4 kg CO2/mi (lifecycle) from @TheICCT theicct.org/news/global-LC… yields 8000 tons CO2. /2

Seems like a good time to help people in the PNW replace gas furnaces with heat pumps that reduce carbon pollution and provide air conditioning. /1 #electrificiation nytimes.com/2021/06/27/us/… Meanwhile, @yoohyun_jung reports on a very sharp SF increase in AC adoption, more than 11 percentage points in 4 years.

We have to make sure the news characterizes this as not only a climate threat but an opportunity. /2

I also have a story like @MayUseFullLane, from Dec 30, 2011. I had a concussion from an avoidable bike crash that caused long-lasting symptoms.
Here is a 🧵.

A favorite memory of Berkeley grad school is biking in the hills for exercise, which I did several times per week. I preferred to meander the steep, winding roads, in neighborhoods I now recognize as having exclusionary zoning: and this afforded safe, scenic streets for some.
