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.

So how exactly should I be positive and have a "let's go fix this!" attitude?

Fix what ? The civilization hell bent on destroying the biosphere and collapsing civilization ?

Climate change is the answer, just try not to not be at the front of the queue, try not to make it worse with your actions and how you vote and enjoy life as best you can. That's about all a sane person can do.

Rees bluntly states, “the human enterprise is effectively subsuming the ecosphere” and “wide-spread societal collapse cannot be averted — collapse is not a problem to be solved, but rather the final stage of a cycle to be endured.”
