No one has a product that can actually stop "climate change". Even those CO2 scrubbers will not put a dent in climate change. As long as the earths magnetic field continues to weaken, things will only get worse.
Airplanes will continue to fall from the sky. Buildings and bridges will collapse. Transformers will blow like at the Hoover Dam yesterday when a crack opened in the magnetic field. EVs will continue to go out of control and kill drivers. Etc...
Warming will eventually give way to cooling which will actually make things worse as resources become more scarce.
Si3N4 can help insulate against some of this, like coating oil/gas pipelines so they dont corrode and blow. Same would be true for other insulating ceramics. Still, there is only so much that can be done to slow the impact.
