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.

Decades after the US buried nuclear waste abroad, climate change could unearth it | melting ice sheets and rising seas could disturb waste from U.S. nuclear projects in Greenland and the Marshall Isla (grist.org)

Most of it is slightly radioactive stuff that you wouldn't want to be around long term but you could stand next to without issue. The problem with it is that you don't want it getting into groundwater/,/food chain etc, because then you drink/consume it, it gets stuck in you and you are 'standing next to it' for the rest of your life.

There is more dangerous waste too, but less of it. That offers the same problem, but worse. Normally, this is actively managed, but obviously not in this case.

The fuel itself (for nuclear ractiors, not relevant for weapons) can be recycled, but it's generally cheaper to get fresh fuel. Additionally, the processes are generally similar to nuclear weapons production, so people start getting nervous.

After i checked on internet, there's some time in history that people back then used to produce depleted uranium bullets for weapon sadly it banned because Geneva Convention, for me that proof nuclear waste can be turned into something useful i guess.....
Maybe we can't turned it into something useful because the limit of technology of our time, i always dreamed someday in the future we can powered our house with some nuclear waste with micro reactor or just powering car (like car in fallout game, although when the car explode it became real problem)
