We can easily build a reliable, low-cost, near-zero-emission power system with the technologies we have today. We don’t need to invent anything new. 🔌💡

I dig really deep into this stuff at think.earth, including GWP, GTP, and GWP* if you are interested.

CO2->C6H12O6->CH4->CO2 again. So the IPCC says the CO2 molecule at the end is not new CO2 and should not count as a new impact. Contrast that with fossil CH4. When it breaks down into CO2 it is new CO2 in the atmosphere. So the impacts of that fossil CO2 count as a new impact.

In a few years that CH4 will break down and turn back into CO2. So in other words, that CO2 molecule that is in the air again is nothing new. It just spent a few months as alfalfa and later a few years as methane.

For example, lets' say that 6 months ago an alfalfa plant grabbed a CO2 molecule out of the atmosphere and turned it into glucose through photosynthesis. Yesterday a cow ate the alfalfa, digested it, and burped out a CH4 molecule.

The CH4 molecules are identical, no matter the source. The IPCC gives the biogenic CH4 a lower value because it comes from carbon dioxide that was already in the atmosphere.

Have you ever once seen the New York Times quote Trump like this?

Hey just gotta tell ya. When you use generative AI to create your image it makes me nauseous and I figure if you used AI for that you probably filled the piece with AI slop too.

Yes by all means, let's play by the rules and wait until we have a supermajority until we do anything!

May I ask where you get this fact? I don't know about the country as a whole, but in the Colorado River Basin, cattle feed like alfalfa and hay dwarfs all other uses—almost half of the Colorado River goes to those crops. www.nature.com/articles/s43...

This is a breathtaking abuse of the law and power by the President of the United States.

America is on the brink of martial law.

Do not be silent.

Giving a bully your lunch money is only a temporary downpayment for future bullying.

We ALL need to step up for the first amendment.

By-the-way, for the record, this ex-Disney employee finds Jimmy Kimmel very talented and funny.

The fact that Disney fears Trump but not the blowback from the American people shows that business leaders having already written us off as defeated.

It is critical that we prove them wrong. Disney must feel real consequences so that others will think twice.

Are you serious? For 11 minutes in space she emitted more CO2 than many people on this planet emit in a lifetime. And then she pulled this stunt to help Bezos greenwash his little toy. She should be ashamed.

Awesome! But are you sure that's not a slime mold?

3/4. If we accept the idea that moving a person from one place to another undoes rights and disempowers the judiciary, we are endorsing the basic Nazism practice that enabled the killing of millions.

A line graph showing atmospheric CO2 levels at Mauna Loa Observatory from 1955 to 2025. The y-axis represents CO2 mole fraction in parts per million (ppm), ranging from 320 to 420 ppm, while the x-axis is years.

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.

@noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!
