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.

Well old is a relative term and its possible you are older than I. I think you misundersand me as I have state quite a few times that we should do everything we can. We should just not be under the delusion that magical future technology will reverse it all and get us back to where we used to be. Is it impossible. No. Is it unlikely. Yes. Its highly unlikely. Everything you base your view on would apply equally to us just finding another perfect planet and the technology to get to it and live happily ever after. But in terms of todays technology and even technology that we can conceivably develop in the next few decades. We can't fix the issue. I really don't understand how you think despair is the only choice if we can't fix everything hunky dory because again I have made it clear I do everything I can to make the best of things and do the best I can for the earth and everyone should as well.

Okay that's great. Your earlier comments made me think you were a doomer. Well you do sound like a doomer, but anyway, I can understand how it's hard to see today how in 200 years we'll have this under control. Every little attempt at sequestration, every insignificant advance, every time an old politician dies in office, will snowball into something amazing. 200 years is a very long time.

oh im a doomer but doomer does not mean give up. Being on the absolute worst track possible is way worse than being on the best. Doomer just means you think there is a greater than 50% chance that society as it is today won't make it or worse with varying degrees between the planet will become unihabitable, humanity won't make it, advanced society won't make it, or probably the brightest is some percent of humanity manages to retain enough knowledge to help jump start things after the really bad parts and learns a fair amount of coping with it all. I fall somewhere in the middle. Some doomers believe in giving up or going full hedonist and not care because nothing matters but thats not me. I am sad for all the lives that will be more miserable than they should be in the coming decades and will do as much as possible to not be responsible for it till my last breath.
