The #BonnClimateConference failed once again to address the key drivers of the #ClimateCrisis [= #FossilFuels]. Delay is the new Denialism.
A ๐Ÿงตon the #FalseSolutions increasingly being pushed in the @UNFCCC negotiations: #CCS #CDR & #geoengineering are dangerous distractions!
Science is crystal clear, the only way to meaningfully reduce emissions is a rapid, equitable, full & funded phase-out of ALL fossil fuels. In this essential #JustTransition, there's is NO space for dangerous distractions such as #CCS or #CarbonRemoval.โ€ฆ

Plants are the best option for capturing CO2

"They naturally extract CO2 from the air and use it as feed. The more CO2 plants absorb, the less CO2 remains trapped in the atmosphere."
2/6 Image
As plants decompose, CO2
is released back to the air

"If left alone, plants are eaten by other organisms and releasing the carbon back to the carbon cycle within months."

"Six models are used in a recent study to analyze the climatic, environmental & socio-economic consequences of #overshooting a C budget consistent with the 1.5ยฐC temp target along the cause-effect chain from emissions & #CarbonRemovals to climate risks & impact."

"Global climatic indicators such as CO2-concentration and mean temperature closely follow the #CarbonBudget #overshoot with mid-century peaks of 50 ppmv and 0.35ยฐC, respectively."
Findings of this study highlight that "investigating #overshoot scenarios requires temporally and spatially differentiated analysis of climate, environmental and socioeconomic systems."

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

...Then suddenly!
๐Ÿ $650m for @Climeworks
๐Ÿ $350m CDR @lowercarbon fund
๐Ÿ ~$1B @stripe Frontier advance market commitment for C removal

@nanransohoff shares the scoopโ€ฆ
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 thereโ€™s no time to lose.

Some great takeaways ๐Ÿ‘‡ @climatetech_vc
"Frontier borrowed a concept from the energy sector - โœจofftakeโœจ 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."

The @IPCC_CH #WGIII has released both its full report, along with a page-turning "Summary for Policymakers"! Some preliminary thoughts from @CarbonGap on the implications for #CarbonRemoval follow.

1/x Image
First a reality check: emissions are outrageously high, STILL havenโ€™t peaked, & continue to reveal massive gaps in ambition, development, and progress (e.g. North America per capita emissions 50% higher than the next highest region, 5x South Asia).

Is there any good news?

2/x Image
Yes, of a sort!

1. Congrats to the 18 countries that actually reduced their emissions!
2. Prosperous, low(er)-carbon economies are becoming more plausible (e.g. Europe's per capita emissions are still high, but emissions per unit GDP are low)
3. Renewables got MUCH cheaper

If you ever wanted to acquire #carbonoffsets, you've surely faced the question of categorization. Here is an easy taxonomy ๐Ÿ‘‡ ๐Ÿงต
1/ Two weeks ago I highlighted the difference between carbon emission reduction and removal projects.

The idea of #CarbonReduction is to pay others to reduce emissions in your place. But your output remains in the system. One plus zero.
2/ #CarbonRemoval on the other hand scrubs carbon directly from the atmosphere. Plus one, minus one.

But technically, the #carbonmarket makes no difference. A ton is a ton.

When I shifted my career to #workonclimate, climate podcasts helped get me informed and up to speed.

Over the last year, Iโ€™ve noticed #podcasts on #climatechange have really stepped up their game.

Here are 10 excellent, recent climate episodes you should listen to now.๐Ÿ‘‡๐Ÿฝ๐Ÿงต
1/ The aviation sector is one of the hardest to decarbonize.

@CatalystPod with @shaylekann gets into the weeds with @rutherdan on the complexities and options for decarbonizing aviation. From SAFs to electric propulsion, this one is a must listen!โ€ฆ
2/ Iโ€™m hearing more about the risks of natural gas in the home. One more reason to consider switching.

The crew at @EnergyvsClimate covers the topic for us on one of their recent episodes with @brucenilles.โ€ฆ

2 years ago, working in global health, I was struggling to find a way to transition my career to climate change.

Since then, I've worked on 10+ climate projects with NGOs and startups. For people looking to break into #climate - here are some strategies that helped me. ๐Ÿ‘‡๐Ÿ‘‡
1/ Figure out your "why".

Yes, climate change is a big, hairy problem. But it's important to understand what about it is personal / significant to you. For 10 years I lived + worked where people will experience CC's worst effects, and I want to work on addressing that injustice.
2/ Listen and learn.

Don't talk. Listen to climate scientists, activists, and entrepreneurs. Honor their contribution by learning from their experiences + reading their work.

Start here: @GretaThunberg @KenCaldeira @CarbonWrangler @KHayhoe @DrKWilkinson @hausfath @JigarShahDC

๐Ÿ“ข Curious about #carbonremoval?
Read my new report @GlobalCCS: "Carbon Removal with #CCS technologies".

@EUCarbonCapture @Bellona_EU
@cleanaircatf @NEP_Brussels

#carboncapture is a unique set of tech because it has a dual role in addressing #climatechange. It can help to reduce emissions from point sources, AND it can remove CO2 from the atmosphere.

Let that sink in.
There are not many solutions out there that do both.

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

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.โ€ฆ Image
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
...this leads to a potential #CDR of 15,591 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:โ€ฆ

Just published, my new article on #mitigationdeterrence from #carbonremoval (in #ClimaticChange )โ€ฆ
What is this about, and why do I think it important?

A thread 1/15
Most climate scientists are so concerned about the risks of climate change that they typically support 'all of the above' ... in other words, behaviour change, energy efficiency, decarbonization, low-carbon technology and carbon removal (not unreasonable on the face of it) 2/15
Our previous work in @NatureClimate shows that such responses are not simply additive, and while some may interact positively, galvanising more action, others - especially promises of future technological solutions - tend to undermine emissions cuts 3/15
