This complex will be world’s first large-scale “green steel” project, according to H2 Green Steel, the Swedish company behind the multi-billion-dollar mill.

Electric Arc Furnaces everywhere - "am I a joke to you?"

Sarcasm aside, I know EAF has its challenges, but this article really acts like coal-fired plants are the only alternative to hydrogen.

I was pleasantly surprised to discover that this article is not about AI!

Is "off pace" a British term? I haven't encountered is in the US.

Clarification from the article...

While projects like H2 Green Steel show momentum is growing, experts say the pace is far too slow.

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.
