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.

We've discovered the breaking point of paradise. Hope the next sentient species is a little less selfish.

Unfortunately, I don't know if it would be possible for another species to reach our level of technology or civilization. We built up our society off of easily accessible energy resources (surface-level coal being our first source of industrial energy). This energy excess allowed us to develop other sources of energy, solar, wind, nuclear, etc. But if you tried starting from zero again, you could never get to this point, at least along the same path, as you need a high level of technology to access any available energy resources. Thus, if any new species took our place, they could only ever rise to the level of the pre-industrial revolution.

That's a good thing, right? The vast majority of the results of technology and "civilization" has turned out to be nothing but a curse on this planet.

To an extent, but we have the chance of transitioning into a solar and wind society and remediate that damage. Subsequent species would not have that potential.

I wasn't even talking about subsequent species, but our own species in the future. As for solar and wind, I'm afraid that the way that population growth and energy consumption growth interacts with the material requirements for solar and wind, that is also going to hit a wall in the not too distant future.
