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.

i would agree with you if not for the very real possibility of total societal collapse due to climate change.

future scientific discoveries, very complex in nature due to the incremental advances already made, need a long time of social stability to be achieved. lots of specialists that spent 20 years in school, lots of special resources, lots of functioning scientific grade equipment, lots of logistical support. if we are talking about complete control over the quantities of whatever gas there is on the atmosphere, then than makes it 1000 more difficult to achieve and implement.

so, no. 200 years will not be enough time to achieve that kind of control over the atmosphere.

So no... 200 years will be enough. Surely you know how much turmoil the world went through as humans were building up the infrastructure to accidentally alter the global climate. It was anything but stable, yet somehow here we are arguing about how long it'll take to fix this. 200 years of targeted research in an unstable world will be more than sufficient. It's happened before, it'll happen again.

so you think that a humanity going from climate disaster to climate disaster on a global scale, will have the resources to achieve total atmospheric control?

and please explain to me how putting co2 in the atmosphere is as easy as taking it out? because i can burn down 20000000 trees in a day but you can't grow 20000000 in a day.

so no, 200 years for total atmospheric, considering the future that waits us, is simply delusional.

It's obviously not as easy. It's a matter of low carbon energy production. Make enough energy and you can do whatever you want.
