I swear i saw Zeke’s chart with concentrations and forcing. I can’t find it. Am I dreaming?!?
something seriously messed up about American transit system. I'll fly 11 hours to seattle, and I need to get to portland. that 45 minute flight is $750 per family of 3. At this point, it's cheaper, faster, and convenienter to take uber from Seattle airport to Portland home.
Interesting differences: all American elite universities are going through massive pro-Palestinian protest. Korean elite universities: (complete silence) But why? It's not about proximity. Is it because you "know someone" who's from Palestine? Is that what it really takes?
Next question! Surfers: do I wear a speedo under the wetsuit or go commando?

@NichollsZeb @Peters_Glen @ClimateCollege @timinmitcham @ConversationEDU @ghgsat @pepcanadell Yes, Maybe another deeper question for follow up is the Concentration Forcing and Warming, which presents a trilemma. An assumption worth examining is for CH4 are we better to burn it producing CO2 than release it?Glen is the Warming graph for CH4 show an uptick at the end?
@HMcJeon That one was just emissions and temperatures as its using a simple TCRE model with just CO2. But it wouldn't be too hard to make a version thats emissions -> concentrations -> forcings -> temperature in FaIR.
This was really fun to think about and write. Thanks to @NatChemEng for the opportunity to reflect on the question of what qualifies as a waste and when it ceases to become a waste. Lots of implications for LCA, CDR, and MRV.
🚨Online now! A World View from Corinne Scown tackles the concept of a 'waste' and the need to differentiate between near- and long-term economic and environmental implications of waste management and utilization. @cdscown Temporary access link here: rdcu.be/dGgdA
JGCRI is advertising for a scientist-manager (essentially a JGCRI deputy director)! This position is for someone who is an active researcher who would also spend a large part of their time managing the institute more broadly. careers.pnnl.gov/jobs/9020
@Peters_Glen Because I saw people whose advocacy & scicomm work I 💚and respect, like Bill McKibben and Jacquelyn Gill, sharing or commenting on it. To me they are climate leaders. But I thought reposting their specific comments to critique them personally would be tacky, so I made it general
@HMcJeon Is the Korean government involved in providing arms and aid to one side or the other? That's the big difference I would think.
@HMcJeon @NB_pik @rishpardikar Just from curiosity, does using Chat GPT means you are defunding google?
News: @bach_lennart @mtyka and I are starting a blog about climate interventions (i.e., carbon dioxide removal and solar radiation modification). First up, Lennart will spiel about putting 600 parasols into space to refract incoming solar radiation. Who will sign up?
@HMcJeon The light rail from Seatac takes you very close to the Amtrak station. Portland also technically has decent public transit (for a US city). There will be some walking involved; or you could do uber/lyft between the stations. Should still be cheaper than alternatives.
@HMcJeon Take Amtrak from Seattle to Portland.
@HMcJeon @Peters_Glen @HarrisBerton @PaulNatsuo I think it can be confidently claimed that, based on empirical evidence, CCS isn't cost-effective at abatement prices of... €0-30/tCO2? Is anyone honestly surprised we've only done (some of) the stuff with blue bars, given our fleeting appetite for emissions reductions per se?
@HMcJeon @rishpardikar @HarrisBerton We have a bit more of a critical view in: agupubs.onlinelibrary.wiley.com/doi/full/10.10…
@HMcJeon @Peters_Glen @AvivCoko @HarrisBerton @PaulNatsuo High-resolution modeling, but not high-resolution jpegs!
@JesseJenkins @HMcJeon @Peters_Glen @AvivCoko @PaulNatsuo Yeah this is really what I am getting at. Let's focus on the under-represented pathways not the overrepresented ones. CCUS legitimately was the best shot at near term coal emissions reductions circa 2010. We just didn't prioritize near term reductions. (Maybe for the best?)
@HMcJeon @rishpardikar @HarrisBerton It's definitely a 'thing' nature.com/articles/s4147…
@HMcJeon @rishpardikar @HarrisBerton Not to my knowledge, but who knows? I would personally critcise optimality approaches, incl. this one, for perhaps being too optimistic about vegetation adaptation and migration timescales. But I am not sure that this is an any way a direct analog to the IAM problem :)
@HMcJeon @rishpardikar @HarrisBerton Since you asked, -realising this is probably a rhetorical Q- yes, they (hypothetical future plants) are optimising C expenditure on N uptake and fixation. agupubs.onlinelibrary.wiley.com/doi/full/10.10… with the basic outcome that future C uptake depends a lot on how many N fixers you have…
