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.

...and? Nothing is going change.

it does help to spread awareness about climate change, and potentially vote for a climate conscious president for once

Doesn't work too well when everyone voting intends to be among the top 10% themselves and no one at all wants to be in the lower 50%. Sorry, but I'm super cynical these days because I (and everyone else in the developed world) learned all about global warming in detail 25+ years ago in elementary school. We knew what it was, what caused it, and how to prevent it... but no one did anything and instead we added 2 billion people to the total population since then. The awareness is already there, but no one is willing to come up with any meaningful implementable solutions because the actual solution is simply lowering emissions overall which people do not want to do.

buying useless stuff, price gouging, consumerist practices like planned obscolecense and just accumulating needless wealth all happen on the expense of climate. future decades will dictate how much people are allowed to live on this earth and hopefully how much wealth is one allowed to accumulate in a lifetime. so far we need to abolish the united states, third world has emission extent next to none, europe being europe, and china with its growth, is at least proactive toward climate (maybe should it work on human rights more maybe ? i dont know) , and even after an afterthought, living in a very hot/cold place is in fact very energy intensive: take for instance the middle east where every household is equipped with AC's running 24/7: living in such climate is just ineffcient ( i would wager living between the northern and southern 30° parallels is a waste of energy ) also is living in canada and scandinavia beyond 60°N: so ideally living in between the 30 and 60° parallels is more efficient, and now you have to adjuste population growth accordingly, and all this is leading to communism since it implies living space sharing. accepting immigrants should be the norm, but at a predetermined rate. also billionaires shouldnt exist: all that accumulated wealth going into waste that could reflect the amount of emissions generated by the person withholding it.

Yes, like I said, we already know all this. I agree with all your points. But no one is willing to do anything about it that makes a meaningful difference. All the things you describe were essentially the same 25 years ago when I first learned about this.

back then climate change (cc) wasn't too obvious: but now we got wildfires, melting icebergs, venise going underwater (which is nice in fact): awareness can spread much quicker now with the advent of internet. people realize the damage when they see immediate consequences, when most of the time it could be late at that point ..
