I've just wrapped up my interim Head of Growth role at @ToucanProtocol to focus on building a protocol at @ReFiDAOist to become an accelerator for the #ReFi movement...

Here's some of what I learned in my time at @ToucanProtocol & a glipse at what's next... 🧵🪡

1/n
🦜 Learnings from @ToucanProtocol 🦜

1. Timing is key — launching in a bull market vs. bear market makes a huge difference

2. Partnerships — @KlimaDAO needed @ToucanProtocol to launch, and visa versa. Find strong partners early.

3. Composability — do less, better.

2/n
3. Build a great team — having an early team with deep technical talent is key to change the world

@raphabenoi, @positonic, @mrjackish, @adamspiers @johnx25bd & @somspace 🌊

4. Know your space — Raph and James spent 18 months ahead of launch researching the carbon market.

Gradually... ⛔#CDR was fringe for years, even as @IPCC_CH sounded the bullhorn

...Then suddenly!
🏁 $650m for @Climeworks
🏁 $350m CDR @lowercarbon fund
🏁 ~$1B @stripe Frontier advance market commitment for C removal

@nanransohoff shares the scoop

climatetechvc.substack.com/p/-a-new-front…
Until this week, the world has collectively bought just 10,000 tonnes of permanent carbon removals - ever.

@nanransohoff and the Frontier crew from intend to spur the market to 6,000,000,000 tonnes by 2050, and there’s no time to lose.

Some great takeaways 👇 @climatetech_vc
"Frontier borrowed a concept from the energy sector - ✨offtake✨ agreements. Suppliers benefit because they can take the guarantee to the bank for project financing. Buyers benefit because they only pay once the carbon has actually been removed."

Der letzte #IPCC-Bericht, der uns noch aus der Krise führen kann, ist (in der Langfassung von fast 3000 Seiten, aber auch in der verkürzten Form für Entscheider von 63 Seiten) eine Zumutung, die viele Politiker nicht verstehen und die ein größeres Publikum nicht erreichen wird.
Das "Politikversagen" ist selbstproduziert, dürfen die Wissenschaftler und Wissenschaftlerinnen hernach nicht beklagen. Mein Appell (ausser der ernst gemeinte @maithi_nk!) wäre eine Debatte (durchaus in Deutsch!) zu zwei Fragen.
Wie muss jetzt, nach dem Bericht und in der realen Lage, die Mitigation-Strategie, wie die Adaptation-Strategie angepasst (verbessert) werden?

1/5 „Every ton of CO₂ emissions adds to global warming” IPCC, SPM.10, AR6, WG1
Bis der Kapitalismus überwunden oder in eine soziale Form transformiert ist🧐, hat die #Klimakrise uns erledigt. Aber „money makes the world go round“, wenn ich eine erfolgreiche #CDR Technologie
2/5 hochskalieren will und Tonnen, Megatonnen und Gigatonnen CO₂ binden möchte, dann brauche ich Investitionen in Menschen und Infrastruktur. JETZT. Inzwischen habe ich gelernt wie man StartUps gründet und kann einen Businessplan erstellen, yay, was auch zur Erkenntnis führt:
3/5 die #Klimakrise ist ein lukratives Geschäft und wer seine CO₂-Zertifikate „preislich attraktiv gestaltet“ verdient damit Geld. In der Aufforstungsbranche gibt es eine Menge Schwindler: Bäume werden an ungeeigneten Standorten gepflanzt, Menschen vertrieben,

1/6 Ich habe die Geschichte mit vielen Kollegys geteilt, weil ich nicht einordnen konnte, ob ich etwas falsch gemacht hatte. Alle waren entsetzt. Auch wenn es in der Wissenschaft deftig zugeht, werden Absprachen nicht gebrochen.
2/6 Ich habe nach der Expedition meine restlichen 4 Monate Stipendium mit frustrierender Jobsuche im Lockdown verbracht. Bei einer Rückkehr nach Deutschland wäre mir das restliche Stipendium entzogen worden, ob ich von Frankreich oder Deutschland aus Jobs suchte war egal.
3/6 Immerhin konnte ich noch ein wenig bretonische Luft schnuppern, eine Menge Palomas mit meiner sehr coolen Vermieterin trinken und Kültür und Sprache lernen. Ein wunderschöner Roadtrip durch die Normandie nach Deutschland hat mich zumindest mit dem Land versöhnt.

1/25 Our new paper on #MitigationDeterrence effect of Greenhouse Gas Removal #GGR #CDR and how to minimize it is out.

Coauthored with @nilsmarkusson @bankfieldbecky @szersynski @dtyfield, @Lancs_LEC

Full paper #openaccess here in EPE: journals.sagepub.com/doi/10.1177/25… @envplane

A 🧵
2/25 Sadly this took a long time to get published … perhaps appropriate for a paper called ‘attractions of delay’ which explains climate procrastination as a predictable outcome of multiple reasons for prevarication. Fortunately the findings are still topical …
3/25 TLDR1: #GGR discourses exemplify how tech promises enable prevarication by being enrolled in scientific, cultural, economic & political processes; many stakeholders share concerns that #MitigationDeterrence is arising from exaggerated expectations of future GGR tech.

**NEW PAPER ALERT**
How much CO2 will we be able to remove from the atmosphere?
How certain are we about this?
How should we act now, given uncertainty around the feasibility of carbon dioxide removal?
Our new paper in @Joule_CP explores these Qs!
1/n
authors.elsevier.com/a/1dxnd925JEG7…
This paper builds on analysis published in @IOPenvironment in June, exploring the risks of #MitigationDeterrence in low-carbon scenarios. We wrote a piece on @CarbonBrief about our findings – check it out here: carbonbrief.org/guest-post-emi…
2/n
In the @Joule_CP paper, we ask experts for their views on the feasible potential for carbon dioxide removal (CDR). We use their responses to construct a probability distribution for future CDR, & explore how uncertainty in future CDR affects near-term climate policy.

काल अर्ध्यरात्री हायकोर्टात राज्यसरकार विरुद्ध #CBI केसची सुनावणी झाली !
अनिल देशमुखाविरोधात असलेल्या #FIR मधील 1-वाझेंची नियुक्ती 2-गृहखात्यातील बदल्या हे दोन उतारे #CBI ने वगळावे ही राज्यसरकाची मागणी आहे कारण ह्याने सरकार पडू शकते !
ह्यावरच एक #शॉर्ट_थ्रेड
सर्वप्रकारणाची सुरवात मार्च 2021 ला झाली जेव्हा मनसुख हिरेण ह्यांचा बद्दल विरोधीपक्षनेते देवेंद्र फडणवीसानी विधानसभेच्या बजेट सेशन मध्ये प्रश्न उपस्थित केले ! प्रश्न काय देवेंद्रजींनी सरकारची पुरती पोलखोल केली ! आणि वाझेंचा #CDR च विधानसभे समोर मांडला !!
#CDR त्यांनी विधानसभे समोरच मांडला कारण , विधानसभेत उपस्थित केलेल्या मुद्द्यांवरून त्यांची चौकशी करताच येत नाही !तरीही तत्कालीन गृहमंत्री अनिल देशमुखांनी अकलेचे जाहीर प्रदर्शन करून फडणवीसांनी #CDR कोठून आणला ह्याची चौकशी करू अशी वलग्ना केली जी आता त्यांच्या सारखीच दिसेनाशी झाली !

1/n A $100m carbon removal @xprize cool! But folks who care about climate should ask some hard questions.

Virgin Earth Challenge $25m prize launched in '07 by @richardbranson. Original prize terms were nonsensical: required a $ bn business to win so the $25m would be meaningless
2/n the Virgin (VEC) prize revamped the terms to say winners had to have pathway to giga scale commercial #CDR, but terms remained deeply ambiguous.

On the plus side, VEC helped us raise funds and attention when I was working to found @CarbonEngineer in '09.
3/n On minus side, the VEC prize diverted resources inside @CarbonEngineer, @Climeworks and other competitors.

@richardbranson and team waited until total funding in space was >> $25 m so impact would have been small, then they punted. Result? Not much.

We have a new paper out on how to use rocks to pull #CO2 out of the air and stabilize it as...rocks.

TL;DR: Surface rocks in Japan could remove 7.6 Gt-CO2/y at 1.5 GJ/t-CO2.

It's open access, so send it to your mother. I know I did.

A thread.

iopscience.iop.org/article/10.108… Image
1/n
We started with a map of all the surface rocks in Japan (~158,000 entries) including the depth of the formations. We narrowed it down to rocks with high Mg or Ca content. We then removed all populated areas, protected ecosystems, etc. to make a map of potential sites. Image
2/n
...this leads to a potential #CDR of 15,591 Gt-CO2...so more than we need for #2DS.
But, most of that rock is volcanic (amorphous).
Previously we found that amorphous compounds react >1,000X slower than equivalent crystalline compounds.
Shameless plug:

IMPORTANT THREAD: Exposing #MumbaiPolice DCP #AbhishekTrimukhe who has been in continuous touch with #RheaChakraborty. This is not the first time Trimukhe has taken law into his own hands, see for yourself:
#Warriors4SSR #ArrestRheaChakraborty #ResignTrimukhe
Wondering why #ArbaazKhan is still out of jail despite being named in an #IPL betting scam? The answer is DCP #AbhishekTrimukhe. The Khans have taken him in as their personal pet! #MumbaiPolice #BettingScam #SalmanKhan #ResignTrimukhe #RheaChakraborty #Warriors4SSR
Why was only @KanganaTeam maligned in the #CDR scam? Because DCP #AbhishekTrimukhe was asked to highlight her name and pin the blame on her. He is deeply involved with the mafia. #ResignTrimukhe #MumbaiPolice #Warriors4SSR #KanganaRanaut @iRaviTiwari

If we went hit net-zero or carbon neutral today, how much carbon do we need to remove to maximize diversity and climate restoration by 2100? See thread for more info on #beyondneutral #climateaction #climatejustice @ExtinctionR
Fossil fuel emissions since 1750, have spread between the air, oceans, and land. By the latest count per the globalcarbonproject.org, the distribution looks like the linked chart. Multiply by 3.664 to convert the amounts to gigatonnes carbon dioxide. (1.7 Tt CO₂ & 2.4 Tt CO₂) Image
How big is this amount? The brown+red bars equals about 656 Gt Carbon by weight which is about 2M Empire State buildings. This amount is roughly equal to all green and blue bars and should be removed to restore the planet. bluebulbprojects.com/measureofthing…

Today seems a great day to mention that I, a climate scientist, am leaving the civil service!

(And no, clearly not top 20 😅)
In February I am joining Oxford University to start up an exciting new research effort in greenhouse gas removals (#GGR #NETs #CDR...). And no doubt other things around #NetZero, science & policy, etc. @TheSmithSchool @oxmartinschool
@TheSmithSchool @oxmartinschool While I am very much looking forward to getting back into academia, it's been a real pleasure working with the climate scientists and others in @beisgovuk (many lurk on Twitter - you know who you are!)

Hoy, en el examen de Derecho Diplomático un profesor me ha llamado #CDR como insulto. Abro hilo ⬇️⬇️
Era un tipo test con la siguiente pregunta:
De acuerdo con el Derecho Internacional General, #Cataluña puede #independizarse?
A) Bajo ninguna circunstancia
B) Sí, de acuerdo con la Resolucion 1516 de la Asamblea General de Naciones Unidas
C) Como resultado de un referéndum.
Yo estaba segura que quería que marcáramos la A (si, yo tampoco sé que tiene que ver con Derecho Diplomático), pero ninguna de las tres era correcta.

So excited to be exhibiting about climate science, #carbontech, and Open NanoCarbon at #Basf19 #sciencetogether! Together we can practice #CDR before it's too late.
Excited to see all kids and adults curious about climate science, carbon tech and semiconducting and metaloid graphene, at the Discovery Day! Let's get more carbon tech faster! @BayAreaSciFest @UCSF @OracleParkSF #stemforkids #stemgirls #weneedmore #CDR ImageImage

Avui @elsmatins ha sortit una vella coneguda, l’eterna estudianta a @UABBarcelona, la @JuliaMorenoR, pres @ShaAcabatNo, activista @Ciudadanos @JovesSCC amb la mateixa jugada de sempre: “Som totalment independents de qualsevol partit polític” ha dit, tota seriosa ella

@elsmatins @UABBarcelona @JuliaMorenoR @ciudadanos @JovesSCC La mateixa @JuliaMorenoR que va sortir a @EspejoPublico de la @susannagriso fa 2 anys fent-se la víctima apolítica amb 2 activistes més. La seva amiga diu que li criden "espanyola!" o "mira, la fatxa!" al campus. Imagineu: "Espanyola!!!" Sí, sí, el que tu diguis.

En el mateix muntatge d'@antena3com, @JuliaMorenoR diu que la @UABBarcelona permet que "difamen informació sobre elles" [sic]. L'altra amiga fent-se passar per una apolítica, marginada pels seus origens, és la @laura_casado96 de @cssabadell, @jovenesCs i @JovesSCC.

Un breu balanç sobre la #RepúblicaCatalana. Estem molt millor que fa 6 mesos, un any o 5 anys perquè:
1.Ens mantenim ferms i combatius
2.Ens han vexat, humiliat, aplicat el #155 , empresonat o obligat a exiliar el nostres representants polítics, socials, rapers, activistes...
3.Hem internacionalitzat el fet català, Catalunya com a nació que vol ser Estat
4.Espanya demostra cada dia més el seu viratge cap a la dreta, intolerància i manca de #Llibertat
5.El judici als #PresosPolitics està demostran-se com a una venjança de l'#1oct
6.Tenim un excelent equip d'advocats que estan posant en evidència la #InJustíciaEspanyola
7. La lliure circulació dels #ExiliatsPolítics a nivell internacional i les sentències a favor en diferents països europeus
8.Les adhesions d'advocats, juristes, polítics, premis Nobel,...
