But first we have to get rid of capitalism and institute democratic socialist planning.

All strains of Socialism are democratic, it's a bit redundant to include unless you're trying to emphasize the democratic factor as opposed to our current system.

whoa whoa whoa

slow down there Karl Marx /s

That would explain a lot of policies.....

And Dick Cheney.

We dont want your toothbrush dude

If you're paying rent to a bank, you don't own your house, at least not yet.

There is still time to change course, however carbon sequestration is becoming a more important part of climate action. Doomerism just acts as an excuse to not take action.

Well it was 25 years in 2019, and I’d round down since we’re in September so yeah, 20 to go.

(Capitalism is a) brutal state of affairs, profoundly inegalitarian - where all existence is evaluated in terms of money alone - is presented to us as ideal. To justify their conservatism, the partisans of the established order cannot really call it ideal or wonderful. So instead, they have decided to say that all the rest is horrible. Sure, they say, we may not live in a condition of perfect Goodness. But we're lucky that we don't live in a condition of Evil. Our democracy is not perfect. But it's better than the bloody dictatorships. Capitalism is unjust. But it's not criminal like Stalinism. We let millions of Africans die of AIDS, but we don't make racist nationalist declarations like Milosevic. We kill Iraqis with our airplanes, but we don't cut their throats with machetes like they do in Rwanda, etc.

Edit: In this they take on the posture of a severely depressed person who views hope as a dangerous delusion.

That's wildly ahistorical. It has allowed the creation of Labor Aristocracy, Proletarians that benefit from the fruits of Imperialism, but Socialist countries like the ones you listed did far more for the working class than Capitalist countries have. You should read Blackshirts and Reds.

“communism” at least as practiced in the USSR, Cuba, North Korea and China.

What are you talking about? Research how many rights women and lgbt people lost when the GDR fell for an example of how wrong-headed this line of thinking is.

For those who want light reading, I highly recommend "Why women had better sex under socialism, and other arguments for economic independence"

And yet despite your copium, we have less than 20 years to take control of our economic system before we all die from climate change.

Capitalism is fuelling climate change. The feudalism and classical democracy and communism of yesteryear aren't the fossil fuel portfolio heavy ideologies that match the destructive power of capitalism.

Does it matter? Ultimately, these are estimates. Educated, data backed estimates, but still estimates.

One larger than expected volcanic eruption, coral reefs dying faster than expected, whatever, all it takes is one or two things to not go the way they're expected and everything speeds up.

20 years or 25 years, the point is we're all kinda fucked unless we do something about it.

What we need to do has been and will continue to be debated ad nauseam, but we know we must do something.
