Climate - truthful information about climate, related activism and politics.

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.

"green iron".. iron oxide?

[–] MrMakabar@slrpnk.net 3 points 1 month ago

That would be red, unless you have something else in it. But it is actually about turning iron ore, which is basically dirty iron oxide, into pure iron:

Fe~2~0~3~ + 3H~2~ → 2Fe + 3 H~2~O

It's this BS where everything done with renewables is green

So if you burn green hydrogen to make iron, the iron is green

Hmmm I heard of studies/prototyping/research to completely overhaul steel production in order to reduce the (gigantic) carbon footprint. It might be linked?

Not just heating it differently, really change the process.. Searching for source, will update.

Edit: not exactly what I was looking for but I found this: https://www.canarymedia.com/articles/clean-industry/us-pledges-up-to-1b-for-two-pioneering-green-steel-projects

Using hydrogen instead of coal, not for heating but for the reaction actually creating iron. I remeber reading about rotating furnace, like the one used to create cement.
