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.

If we want to build a stable 100% renewable energy electrical grid we need backup power station for when there is no sun or wind.

Right now coal and gas power stations are mainly used but renewables option are limited.

Hydro can help to an extent but the locations and power output are limited, battery storage help to smooth production but it's not enough for seasonal variation.

Nuclear could work perfectly but I'm losing hope on trying to convince people that a bit of nuclear would help to each a 100% renewable energy grid.

The last option is biomass, it can be vertuous is the wood resource is well managed or terribly damaging for the environment if not.

Do I think biomass power station are needed of we want to transition.
