Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

We're scientists. We know the climate's changing. And we know why. (www.theclimatebrink.com)

I'm an engineer. I've built a system to try and start fixing this, but no one likes the numbers... https://youtube.com/@narcimalgae

40 gallons a person minimum. Water holds 8 times the gasous CO2 as the atmosphere it is exposed to. (Oxygen is 1:1) Algae pulls the CO2 out of the water and converts it to solid biomass. Oxygen is offgassed. This is grade school photosynthesis. 1 lb dry algae is 4lbs gasous CO2 sequestered. Don't be a dunce and convert it right back to biofuel or you've wasted a lot of time and energy.

Yes yes, but what is the profit margin here?

I'll check your videos out later, I'm just on break.

I'm sure your videos cover it, but what would you suggest to do with the biomass?

I want to try converting my stock to algenic acid. Really any process that doesn't result in burning it and putting the carbon back in the atmosphere. I personally don't grow in a clean enough environment for food-algae, and recommend anyone wanting to grow algae for food to grow regional vegetables instead.

That's really interesting; I'll do some reading about that when I'm home. Thanks for the reply!
