Does anyone want to hear about the ocean CDR MRV non-profit @_cworthy that @matt_c_long @alicia_karspeck and I are building? 2️⃣At [C]worthy, we believe MRV for ocean CDR will rely heavily on numerical models as they provide the only real means of effectively quantifying the dispersion of CDR signals within ocean flows.

There should be a #ClimateTwitter #EnergyTwitter FAQ. 1. Where does the concept of "carbon footprint" come from?

1️⃣ It's hard for people to visualize removing tons or billions of tons of CO₂. What if we talked about CO₂ removal (CDR) like a time machine (e.g., this machine will take us back 5 minutes*)?

*ignoring the hysteresis in the relationship between CO₂ and climate change impacts. 2️⃣ So if global CO₂ emissions is 38.9 GtCO₂/yr, and the Climeworks Orca plant removes 4000 tCO₂/yr, it's a time machine that takes us back 3 seconds every year.

In the 40s and 50s, atomic scientists though about nuclear as energy of the future. The US Atomic Energy Commission published Energy in the Future in 1953 where they argued that burning fossil fuel releases CO₂, which affects the climate & sea level 1/n

It's worth noting that Keeling's initial research on CO₂ was funded by the US Atomic Energy Commission. 2/n

🧵 Enough people have shared this clipping from the NZ paper Rodney and Otamatea Times, Waitemata and Kaipara Gazette that it's worth looking at the original Popular Mechanics article from which it's reprinted, also from 1912. 1/5

"Remarkable Weather of 1911", starts by describing the extreme weather of 1911 ("cities baked and gasped for breath" "flood-gates of the heavens were opened" "violent storms" "killing frost") and above average temps.

It speculated this is part of natural variability. 2/5
