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.

You mean removing all the parks in favour of car parks and apartments wasn't actually a good idea and that the short-term profiteering will have long-term consequences that we'll be paying for for generations? Who foresaw such a thing?

Guerilla gardening. Your city won't do it? Do it yourself

I'm all for it, but this does still require patches of soil in the cities that are rapidly getting paved over.

For a few years my wife and I were thinking of moving to Saigon, and this was one of the biggest reasons we chose not to. When we were considering it, they were even reducing the amount of green spaces, which is obviously the exact wrong direction.

EG this article from 2017 https://saigoneer.com/society/society-categories/10578-photos-a-bird-s-eye-view-of-saigon-s-remaining-green-spaces and this article from 2019 https://saigoneer.com/saigon-news/16954-saigon-s-urban-green-coverage-is-poor,-but-little-is-done-to-speed-up-park-projects

Yeah, I hate this. I remember when I was a kid (almost two decades ago), there used to be giant trees all over the city. Now, when you look out the window, it's just an endless sea of grey.
