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.

Taking CO2 out of the air would be an absurdly expensive way to fight climate change (www.theverge.com)

Algae does it for free on a massive scale.

We'll put a stop to that!

Are you being sarcastic? I think this defeatist attitude is shit, and people need to focus on real practical cheap solutions rather than doomerism. Algae is the best solution we have, it already does most of the job for us.

The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.

You think?

Dollar for dollar, planting trees works better then current CO2 connectors. Algae could be industrialized as a source of carbon neutral fossil fuel alternative.

Indeed, and using algae based fuels would make it carbon negative because it would in turn store the carbon it releases cyclically. Algae can be dehydrated, compacted, and stored for extremely dense carbon storage. Planting trees is good as well, also for ecological reasons.
