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.

Many scientists don’t want to tell the truth about climate change. Here’s why (www.wbur.org)

I tend to think that there’s maybe one or two generations left to live before society collapses due to this shit

I'm in the 1-2 decades camp. Maybe less. I think you'll (and myself) will be plenty young to enjoy some of the terribleness.

It took a boat going a bit sideways in a ditch to grind the global economy to a practical halt. Climate change makes something like the pandemic look like a feather duster. The whole system is ridiculously fragile.

Very true. I mean, people think rising sea levels just means losing beach front property, and they ignore the cataclysmic chain reaction of mass fish die off, acidification, and severe weather. Not to mention the increasing temperatures are allowing for pathogens - in particularly fungi to adapt to higher average temperatures, which means humans (and other mammals) won't be able to use fevers to fight them off. We'll continue to see more novel diseases, pandemics, etc. It's for the best anyway. The sooner the earth can get rid of us, the sooner it can return to equilibrium.
