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.

Another huge hydro dam is being built in British Columbia, on Canada's west coast.

The article describes the coming destruction of farmland and wildlife habitat.

“We have to decarbonize our economy, but it can’t be on the back of flooding more river valleys.”

But as long as the economy grows, more sacrifice zones like this will be made. And if you don't like flooded river valleys, go take a look at tar sands pits or mountaintop removals.

The continued cluster fuck of killing the biosphere to save the planet. Hydros not even close to clean, or green and generates heaps of GHG emsisons from rotting veg.

Clean energy might help deal with emissions, but it does nothing to reverse deforestation, overfishing, soil depletion and mass extinction. A growth-obsessed economy powered by clean energy will still tip us into ecological disaster.” - Jason Hickel
