The line in the lowest black, corresponds to SSP2 RCP 2.6 GCAM4

I have the sheets I used for the paper in google drive. https://drive.google.com/drive/u/0/folders/1LlqAwfGhQR72Q4O8qh1OW7owMroctGjz
The original RCPs are in iamc_db_co2_sorted.xlsx and lists that SSP2 RCP 2.6 GCAM4 is the pathway with the fewest emissions.
Shannon A. Fiume
@safiume
Ack. I completely forgot about the entirety of radiative forcing. So, RCP 2.6 equals CO₂-eq, and not directly CO₂. Under RCP 2.6, if radiative forcing percentages were what they were when the Earth last experienced rf 2.6, then actual CO₂ ppm should be 375 ppm. That brings the orange curves down to end adjusted to about 375 ppm. That's likely not enough to reverse the damage to the polar regions but it's likely just barely be enough to not cause total deglacation depending on how long elevated levels persist.

At the Maker Faire!!!! Please do drop by today.

@titojankowski
hows was Maker Faire @safiume?
Shannon A. Fiume
@safiume
Sorry, it's been a long few days...
Good! More later, say after The Conference on Negative CO2.

What I outlined in the paper as the method to restore the climate, if it were possible, as in if we had the tech to accomplish that much removal, would restore the climate and keep it restored.
!@#$%^&^%!!^$!^%$!%^$!!!!!!!!
I'll get these actual model runs include in the paper to have it hopfully ready for final review Monday.
Shannon A. Fiume
@safiume
I'm still tracking down the error and uncertainty of the model for these numbers.

@safiume
I bicycled to the meetup... I'm in the seahorse jersey.

@safiume
It's been ages! What a year. I have my head in a prototype for Autofracture and with the latest SR1.5, everyone is talking about carbon again.
The next ONC meetup is this evening at either Hacker Dojo or a cafe in Palo Alto. I'm half tempted to do a cafe near the Palo Alto train station.
Shannon A. Fiume
@safiume
I've started the meetup at Peets in Santa Clara. I'm outside, and on a hangouts.
Tito Jankowski
@titojankowski
how was the meetup @safiume, any new ideas?
Shannon A. Fiume
@safiume
@titojankowski It was very lightly attended. Met a new member Scott and refereed him to the CARBON RUSH -- The Next Mega-Trillion Frontier meetup and http://manylabs.org. He's reviewing the current entrepreneurial carbon projects to decide how to contribute.

The meetup is happening at Peets!

@safiume
@/all I created a jupyter notebook of the CDR Experiments for Susan's and my upcoming paper. The notebook and magicc input files for the new paper are on github: https://github.com/hsbay/cdrmex.
I do need volunteers for the Maker Faire! 5/17-19! And especially when I'm talking on CDR on the 18th. dm me.
Shannon A. Fiume
@safiume
I should get me some Azolla! We've got a tough precedent to beat.
Shannon A. Fiume
@safiume
Meetup today! It's a virtual one. Dm for the conference call link.
Shannon A. Fiume
@safiume
Meetup has been moved to tomorrow at 12:30. See all of you then.
ONC Meetup, 9/20 12:30 PDT: https://meet.google.com/fuj-wszx-pqv
Shannon A. Fiume
@safiume
ONC meetup is happening now.
I'm at Peet's in Santa Clara.
Shannon A. Fiume
@safiume
OnC will be Discovery Days in SR, and SF.
Shannon A. Fiume
@safiume
I'm at the tables outside of Peet's, however, I'll have to move either into Peet's or nearby as I'm low on power.
Shannon A. Fiume
@safiume
I'm in the ferry building near the Cowgirl Creamery, at high table nearest to a power outlet.

Hi! There, virtual meeting tonight. DM for conference line details.
(And I'll physically be at the UCSF lib on Parnassus St in SF tonight.)
Shannon A. Fiume
@safiume
the UCSF network isn't allowing ghangouts. dm or drop by for the meetup.
Shannon A. Fiume
@safiume
Wow, the journal article I want to read is paywalled by Elsevier as the UCs didn't renew their subscription. I'll see if I can get this from a CSU otherwise I'll visit Stanford.
Shannon A. Fiume
@safiume
Once ONC finds the fastest way to go to solid C from CO₂, it allows nearly all of these markets to store carbon and become a Negative Emissions Technology: https://docs.google.com/drawings/d/1pZRQcMRGDybmGChXYFyawuOJWIIo8RXlq4ngw2csyms/. I say nearly all because forming a carbonate rock is likely to be faster than an electrochemical process.
Shannon A. Fiume
@safiume
Why create a portfolio allocation? Because most people are touting individual solutions but they can't globally reach gigatonne scale. A combined retooling of multiple industries, albeit resource-intensive, will allow us to have multiple markets when aggregated capable of negative emissions in the gigatonne scale. Other people have simply been overwhelmed with the negative and are trying to tune out to the climate discussion. This document is meant to be a seed to incentivize thinking different about carbon use and reengineering products to ultimately create a market to pay for DAC.

@safiume
Meetup today, here on gitter!
Feel free to direct message @safiume here via Gitter or chat in this room.
Shannon A. Fiume
@safiume
No meetup tonight. I've had health issues unrelated to COVID-19, none the less have been taking up too much time. Hopefully next week, I'll bring ONC back up to full speed. Best everyone.
Shannon A. Fiume
@safiume
I've changed the survey to move the physical meetups to not occur till post Q3 2021 or medical intervention for COVID-19. There's no reason to incur extra risk.
Shannon A. Fiume
@safiume
Meetup moved to 11:30 (AM) PDT June 18th, in this chatroom. Hope to see you here.
