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.

Australia has been a leader on home solar.

Green Iron and steel is an important market for H2 electrolysis because all of the fertilizer plants are mega plants right next door to grey H2 plants.

But human sustainability can't be a PR/political game. International carbon taxes are needed to justify these investments, otherwise we will end up reminiscing how for a brief moment in our history, shareholders were rewarded richly.

What do you mean about fertilizer?

Most hydrogen made today is used to make ammonia of which most of that is used to make fertilizer.
