We’ve calculated that genetically modified plants could stop the increase in atmospheric nitrous oxide and reduce levels to pre-industrial by the end of the century. Impossible? Let’s try the research and see. youtu.be/vHZZfKukT4M

Our proposed bio technology could prevent N2O emissions and remove legacy nitrous oxide from the atmosphere, but it was rejected by USDA and DOE. Why because it was deemed too difficult. youtu.be/vHZZfKukT4M

Contrary to the regenerative ranching racquet, this meta-analysis further adds to the consensus:
Natural ecosystems contain more stable soil carbon stores than even the best agricultural land, and their preservation (& restoration as best as possible) is therefore crucial.

They are available at present only in Canada. The USDA is still considering our application for approval in the USA but they are available for pre-sale.

Sorry, all livestock ag drives climate change: methane, nitrous oxide & CO2 emissions + 'carbon opportunity costs" on all the land used, that could otherwise store more carbon. So-called regen grazing (no agreed definition) can often be the worst, with much greenwash. E.g.: bsky.app/profile/nich...

Since nitrous oxide lifetime in the atmosphere is about 200 years, most of the old nitrous oxide is still up there. Only one method can prevent emissions and remove nitrous oxide from the atmosphere: youtu.be/vHZZfKukT4M

The science showing that CO2 absorbs heat, and that fossil fuels could warm the earth, was made by a great scientist, Eunice Newton Foote, who published her work in 1856. The subsequent science follows her pioneering work and insights.

Only Q is whether you can boil the water more efficiently. Still boiling water.

some ways to generate electricity
A) use sunlight to drive photosynthesis in plants, let plants die, wait ~100 million years, dig up fossilized plants, burn plants, use heat to boil water, use steam to drive a rotating turbine, use generator to make electrons

Should greenhouse gases, other than CO2 count as offsets even though they don’t reduce the CO2 in the atmosphere? For instance, plant expression of nitrous oxide reductase could reduce global warming for years, but we still have the same amount of CO2 in the atmosphere.

So what do we know about the ultimate remaining non-decarbonized sources of greenhouse gases? Statistics says 2T euros in the 2030s! That is based on the overpriced offsets on the present market, but perhaps it is a rough estimate of the eventual difficult to decarbonize market

If we can get nitrous oxide reductase to work and plants the uptake from the atmosphere through the leaves will surpass even the root uptake making it accessible to degradation the legacy nitrous oxide in the atmosphere from other processes.
Nitrous oxide emissions from agriculture are not only coming from soil. They’re also flowing through the streams that run alongside farms, a recent study finds.

A new study finds the gas is also coming from polluted water.

By the end of the century, it looks to me as if the greatest concentration of capital will be in carbon offsets. Trillions of dollars. Only sustainable if they are our rigorous and confirmable.
