What helps me most is pacing. Then Ivabradin, LDN, HBOT, Arginin (earlier also Nikotine patches helped tremendously). Plus various supplements to push blood results into order.

My LongCovid symptoms are ME/CFS-similar with PEM, fatugue and dysautonomia being the biggest challenges. I’d say I am a moderate case, though working full-time or doing sports is not possible without crashing. Things improve very slowly.

Your overall risk of getting LongCOVID increases with each addtl. infection.

One scales by concentration and the other scales by distribution.
Real climate progress doesn’t come from choosing the “best” architecture. It comes from expanding the set of places where carbon removal is possible at all.

Graph description: Monthly and annual leachate alkalinity in tCO2/ha/year (delta to control) for each feedstock with 95% confidence intervals and 10-90% percentile ranges. Our data is available on Github.

The graph shows the deltas to control (increased TA compared to control is our indicator for successful CDR). The colors depict the years 2023-2025 and we can see how the weathering signals decrease over time, blues are lower than reds, greens are even lower.

PS: This is an update to a graph that we showed in our report last summer (linked below), now with one more year of data. The graph shows data from about 4,000 leachate measurements of TA for >60 variations (=rock/soil combinations) with 95% confidence interval.

To assess that we are in the process of analyzing thousands of samples from our soil columns using various methods. We want to know where the carbon and the cations have gone. The results will be shown in our conference in June. Stay tuned!

One note: Looking at the TA export as a measurement of CDR is looking at the lower bound of what has actually happened in the soil column. We just know that the CDR effect was not lower than this. But it might be higher.

The results look more promising when individual soil/feedstock combinations are taken into account (see our report).

Now, with data for the third year we can see that steel slag was the only feedstock that caused an annual CDR effect as-measured-by-TA-export above 0 that was sustained beyond the first year. All other data points for 2nd and 3rd year fell back into insignificant territory.

(as measured by increased TA export in the leachate, which could be underestimating the actual weathering).

In our greenhouse experiment with 400 pots we found that when assessing the results without taking soils into account only steel slag and cement were able to generate significant Carbon Dioxide Removal regardless of soil

Building companies, and now working on climate and enhanced weathering, taught me that progress comes from staying on a problem for a decade, not chasing novelty every two years.
