Adding those biochar nanoparticles
 to the polymer glass deck improved the board's ability to absorb energy
 during hard carving turns, which is then released on rebounding at the 
end of the turn, boosting acceleration. The biochar improved the board's
 ability to store energy when it bends and shed it when released. 
Vibration is transformed from speed loss (energy loss to heat and noise)
 to speed gain as the nano-sized biochar particles work like a capacitor
 within the composite material, capturing and returning the energy 
according to the bending stage of the board. 
If quantum physics is not your thing, then consider that Bormoloni 
and other boarders can win more than trophies—they can earn carbon 
credits. Each board can be certified and registered as a temporary 
C-sink to offset warming and draw down greenhouse gas emissions. So can 
the same materials when used in wind turbine blades, F1 racing tires, 
Tour d’France bikes, pro-tour golf clubs, and tennis rackets.
The
 nine-page review gathered and summarized the potential of biochar to 
return Earth’s atmospheric greenhouse to pre-industrial balance within a
 time frame that humans can survive. 
This essay now describes the best current 
calculations for how quickly biochar can bring humans back from the 
brink of climate collapse. You can afford $7 to support a good cause, 
right? What follows is the best part.
 
Weng and Cowie took a deep dive into 19 published studies
 estimating the climate change mitigation potential of biochar, 
reconciling reference metrics and individual study limitations. The 
upper-bound, most rosy scenario for drawdown was 11 PgCO2e yr-1, or 11 
petagrams or gigatons—billion metric tons—of greenhouse gas removal per 
year. One would need to contrast that with present-day, human-added 
emissions, which are approximately 40 billion tons of carbon dioxide or 
50 billion tons of “carbon dioxide equivalent” when including trace 
gases like methane, fluorocarbons, and soot, as well as changes to land 
use, the water cycle, and various carbon sink losses. 

If, 
through some yet-to-be-discovered magic, or perhaps the same sort of 
Facebook algorithms that elected Trump, supercharged Covid’s R-naught, 
and gave Nazi tech billionaires like Peter Thiel and Elon Musk control 
of the world, we could suddenly reverse course and attain zero 
emissions—humanity’s Brigadoon—then 11 billion tons per year drawdown 
would arrest the melting at Earth’s poles in a mere 50 years, or by 
2075.
To estimate how long it would take for atmospheric CO₂ 
concentrations to return to 350 ppm under the scenario described—zero 
emissions plus carbon dioxide removal (CDR) of 11 PgCO₂e/year—we 
consider the current atmospheric CO₂ level, the total amount of CO₂ that
 needs to be removed, and the annual removal rate.
Current CO₂ Levels: Atmospheric CO₂ is 
“officially” ~420 ppm as of 2025. It may effectively be 526-567 ppm CO2e
 when accounting for the McPherson Paradox (aerosol masking). We’ll use the lower number.
Target
 Reduction: To return to 350 ppm, approximately 70 ppm of CO₂ must be 
removed. Each ppm corresponds to roughly 7.8 gigatonnes (Gt) of CO₂, 
meaning a total removal of about 546 GtCO₂ is required.
Removal Rate: The proposed CDR rate is 11 PgCO₂/year (11 GtCO₂/year).
Calculation:
The time required can be calculated by dividing the total amount of CO₂ to be removed by the annual removal rate:
Time = Total CO2 to remove / Annual removal rate
Time = 546 PgCO2 / 11 GtCO2/y = 49.6 years.
Unfortunately, it is not that simple. The
 ocean is our carbon piggy bank, absorbing excess CO2 (becoming more 
acidic in the process) and slowly—very slowly—depositing the excess 
carbon through corals, whale poop, and sedimentation. Approximately 
15–25% of atmospheric CO₂ removed will be compensated by ocean 
outgassing over decadal timescales, based on studies of air-sea CO₂ flux
 dynamics. Over century timescales, the rebound effect of ocean 
outgassing approaches 50%, meaning you have to remove twice as much CO2 
from the air to reach an equilibrium concentration between atmosphere 
and ocean.
But let’s assume a 20% compensation rate as a 
reasonable goal for our 21st-century drawdown. Accounting for 20% ocean 
outgassing, the effective removal rate becomes 8.8 PgCO2/y (11 Pg less 
20%). 
Time = 546 PgCO2 / 8.8 GtCO2/y = 62 years.
So, 
instead of 2075 (if Elon Musk and the Trump Tariffs attain Net Zero 
between now and December), and would scale biochar on top of that, 
instantaneously, we would be looking at 2087 before the ice melt stops, 
polar vortices calm, extreme weather abates, and the Atlantic 
overturning circulation returns to its prior poleward heat transfer 
pattern.
Maybe.
It might take that long were it not for Elisa Caffont and Maurizio Bormolini’s breathtaking slalom runs.
You
 see, Weng and Cowie, like nearly all hallowed researchers gone before, 
limited their research to crop residues and agricultural applications 
for biochar. As Kathleen Draper (who co-authored Hans Peter Schmidt’s 
snowboarding article for 
the Biochar Journal) and I described in our 2019 book, Burn: Igniting a New Carbon Drawdown Economy to End the Climate Crisis,
 the non-agricultural uses for biochar (cement, asphalt, batteries, 
water filtration and desalination, steelmaking, alloy refining, data 
center geothermal cooling pumps, kitty litter, etc.):- Will remove 5 times more carbon from the atmosphere annually once commercial potential is realized;
- Can use feedstocks (marine algae, municipal solid wastes, plastics, medically contaminated biowastes) unsuited or too dangerous for soil applications; and
- Will have “inertinite” durabilities measured in the hundreds of millions of years, in some cases.
Schmidt concludes his article by saying:
Sports gear is just the beginning. Under the name of C-Thinx, as we call the NanoC containing C-Sink materials, we work on reducing vibrations of wind turbine rotor blades and, thus, increasing their energy efficiency. It will further be employed in carbon concrete, extending the lifespan of constructions such as bridges and tunnels. When integrated into asphalt for roads, it will significantly reduce tire vibration, thereby lowering noise pollution, fuel consumption, and gum abrasion while increasing the longevity of the asphalt. There are many more advanced biocarbon materials on the list, poised to replace conventional petrochemical products.
Now let’s assume that 
industries like biochar snowboards and bioasphalt were scaled to their 
maximum. How many years would we need to return the atmosphere to 350 
ppmv CO2e?
Seventeen years.
It takes about the same time to train a world-class snowboarder.
