Our best strategy for assessing the efficacy of ocean alkalinity enhancement (OAE) involves running computationally expensive climate models. Here, we developed a statistical technique that encapsulates the climatic response to OAE interventions, simplifying the OAE carbon accounting problem. 🌊🧪
Impulse response functions as a framework for quantifying ocean-based carbon dioxide removal
Abstract. Limiting global warming to 2 °C by the end of the century requires dramatically reducing CO2 emissions, and also implementing carbon dioxide removal (CDR) technologies. Ocean-based CDR throu...

Interactions between ocean alkalinity enhancement and phytoplankton in an Earth system model
Abstract. The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered...

ICE are fucking traitors to this country and are committing crimes indiscriminately!
To ICE: ‘When the rapist felon is out of office you will be hunted and you will pay for your crimes!’

the second half of this is a compilation just from one day of ICE & CBP saying repeatedly: you have no rights except what I say, assaulting people, arresting ppl without warrant or charge

Watch this especially the 2nd half which shows the many illegal acts ICE and other fed secret police commit. I think they are trying to get opposed by local police so trump can call it an insurrection and send troops in.

This study led by @aaronferderer.bsky.social tested how 5 diatom species respond to broad ranges of seawater carbonate conditions. Goal was to determine carbonate chemistry niches and to inform Ocean Alkalinity Enhancement (OAE) and Ocean Acidification (OA)

Carbonate chemistry fitness landscapes inform diatom resilience to future perturbations
Diatom growth rates are determined by concentrations of CO2 and H+ across broad carbonate chemistry landscapes.

The Avelo planes still mostly use VXP(XX) and Omni planes always use their standard OAE callsigns. GlobalX and Eastern Air Express + whatever Gulfstream they're hiring this week all use TYSON.

SPACE FACTS: DAY 154/365🧪🛰️🔭
To the east (west) just before dawn (after sunset), there is a column of diffuse light coming up from the horizon. This is zodiacal light, sunlight scattering off interplanetary dust grains from sublimating comets and the Martian surface.

Experiment 2 tested OAE through olivine when incubated with natural beach sand. This was contrasted to a control where only sand was incubated. Treatment and control were exposed to a gradient of DIC, corresponding to a pH of 7.9 (low DIC) to 6.8 (high DIC).

This lovely figure from Gambacorta et al's 2024 review on the Toarcian OAE is why I can guarantee scientists have not united and created a climate change conspiracy.
Look at it. We can't agree on anything 😅
