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.

Then we use the wood.

Wood for construction locks up the carbon for decades to centuries.

Leaves become animal fodder and from there become fertilizer.

The more we replace disposable plastic with disposable paper the fewer microplastics we add to the environment.

If wood ends up in a landfill, its carbon gets locked underground for centuries. An anoxic landfill, and it could stay down there until it turns into oil. Dump it in the ocean and it sinks down among the shipwrecks and becomes fish habitat. And the worst poison wood leaches into the environment is the stuff black walnut uses to kill other plants.

Compared to everything else we make crap out of, wood is an ecological miracle.

And if all else fails wood for heat and power is literally carbon neutral.
