2025-05-22 China’s Emissions Peak Is Over
Sam Evans Electric Viking video tells us about the change China is making to solar and wind and away from coal and natural gas. Planned new coal power plants are being cancelled. CO2! Emissions and pollution are not rising, they are falling.
2025-04-17 Trump Preventing Decarbonization Of Cement
Cement and concrete is used almost everywhere. They contribute 8% of the CO2 emitted into the atmosphere7. Federal grants to decarbonize cement and concrete are being withheld. https://floodlightnews.org/cement-is-a-climate-menace-under-trump-fixing-it-just-got-harder/?ref=im-a-reader-newsletter
2025-04-13 Cement Production Will Still Contribute CO2
Quote: “”Cement production is not carbon intensive solely due to energy use, but because heating limestone (CaCO₃) creates lime (CaO) and carbon dioxide (CO₂). Even completely carbon-free energy cement production would contribute about 5% of the total global CO₂ emitted annually, at current levels of cement production. Cement will not be decarbonized without addressing both

2024-10-03 Dr. Tyson Explains How Oceans Absorb And Release CO2
Neil deGrasse Tyson explains that the CO2 in the atmosphere is absorbed by the oceans until they reach equilibrium. If we stopped burning fossil fuels today, the CO2 reduction in the atmosphere would cause the CO2 to come out of the oceans for a very long time in order to reestablish the equilibrium. So it

2024-04-27 Ocean Carbon Removal
A long article describing several methods and how far they have been researched. I like the enhanced rock weathering – it’s something that may be able to be done with very low use of fossil fuels. It’s not difficult to crush rock to dust. But there are pros and cons to each of the methods.
