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.

a knife-edge

lol .... the options are simple here

  • either let corporations take over the world and we all die a heat death or some climate catastrophe one by one over the next hundred to two hundred years and drive the human species and the majority of all large animals in the world to extinction.

  • or we do something about reining in corporate control of the world and we all band together to save ourselves from climate catastrophe.

All our lives and our global civilization is at stake here, there's no debate about it. You can argue as much as you want about economics and finances and corporations and businesses ... none of it will matter when our global civilization collapses and we all slowly die out.

Someone's thrown a Molotov cocktail through the living room window and the house is on fire right now ... do we want to do something about the house burning down ... or do we want to have a debate about what to do about our monthly finances and who owns or will inherit the furniture and decorations?

You couldn't have put it any simpler. Chances are, humanity will put what it wants over what it needs.

Globally, advanced militaries run on petroleum. The US military is the largest user of petroleum in the world. Petroleum has been the dominant military asset of the last century. There are lots of initiatives to switch to renewables, but logistically it's not possible on the time line we need.

This is the big secret. The military industrial complex runs the US. It needs oil to control the world, which it uses to get more oil. No politician will ever dismantle the military. You know what people who get in the way of petroleum extraction get called? Terrorists.

The entire power structure of the US, Canada, Europe, etc, relies on the continued military domination of former colonies. It's a house of cards built on oil.

Any path away from oil is also a path away from militarism, colonialism, and corporate domination. Climate change will kill everyone, and the ruling class is willing to sacrifice as many people as it takes to figure out a new resource they can control to maintain power. The problem is that there's no other resource, so they're just going to sacrifice everyone until the system collapses.

This is what we're fighting against, and we need to face the fact that it's not just some people who don't understand. It's ghouls and windigos. We are fighting monsters who know full well the house is burning. They are sacrificing us to get to safety.

The many, many species facing extinction as a result of changing climates & pollution.

Probably in the atmosphere in the form of CO2.
