The fact that “alternative transportation” just means you’re not in a car tells you everything that’s wrong with our transportation system.

Google, Meta, Microsoft, and Salesforce want to purchase up to 20 million tonnes of nature-based CDR between now and 2030.

That’s a time machine that takes us back ~43 minutes in a year.

Some of America’s greatest triumphs, like the moon landings or the D-Day landings, succeeded because of science.

The current anti-science campaign by the political class makes zero sense.

Rich countries sent climate funding to the developing world with interest rates or strings attached that benefited the lending nations.

What makes us think CO₂ removal () will be any different? Why would rich countries spend trillions of dollars to benefit the developing world?

Nuclear power would be a climate solution if we could get nuclear power plants permitted and built fast enough, cheap enough, and safe enough. What if direct air capture were the same?

This Google spinoff aims to remove 500 tonnes of CO₂ per year from the atmosphere, which is a time machine that takes us back less than a second each year. 🙃

I’m not against cute things that people do, but this will never be a climate solution. What will? Wind and solar, electrification, energy efficiency, stopping methane leakage.
