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.

"Positivity" is a weird thing. You can be rich and sad because your neighbor is more rich. You can be working yourself ragged and happy because it's a competition on a topic that you love.

You can be Caribbean pirates dancing with death fighting for life and liberty against cartoonishly evil empires and you can be suffering from depression in safety with people you love.

You can live in the shadow of a toxic chemical plant treasuring every moment you spend with your family or you can have a private island and prosperous family and feel hollow.

Climate change will almost certainly lead to violent clashes between groups and states unwilling to give up unsustainable wealth and privilege and also between them and people just trying to survive, on a scale never before seen on Earth. Nuclear, biological, and mass autonomous weapons may be used. Over a billion violent deaths next century seems likely, and over seven billion violent deaths is very possible.

But that doesn't mean we have to feel negative all the time while living through that. That depends on what we do and what we're working for. Building anarchist spaces, I haven't felt this alive since I was a child. People are facing the risk of permanent injury, prison, and worse, but they look more alive than 99% of wage workers.

We have a chance to build a better world with our own hands as the old one burns, for however many millions of people will be alive in the 22nd century if not for ourselves. Every thing we do matters to us, to our friends, to our comrades, and to the world. Maybe we'll end up in a place where despair is appropriate, but it is not now.

I don't know if this counts as a "positive imagined future", but it is the one we are heading towards and I am happy.
