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.

Nice idea, but in my area for example this wouldn't be a good solution. I live in a flood prone area.

Luckily there are many different solutions. What I find quite interesting are simple techs that also don't require electricity, like a heat chimney, or a air supply from underground, air-flow designs in general.

Also, with already built houses there are even simple possibilities. What I've done successfully is letting a tree grow on the south west side, now in the evenings my walls and with that the inside area is much cooler.

This particular house was on a decent sized hill in the middle of a large flat area. I think the sea would have to rise 750ft or the closest river would have to flood half a state for it to flood their house. It wouldn't work in my area either. I live in a large valley.

It definitely requires tons of money to do. I wonder if they've made back the difference in savings yet?

People really underestimate what a couple trees can do when strategically placed. Or how drastic the temperature difference can be between flat lawn and cops of trees. They're giant cellulose and lignen heat sinks.
