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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Chinese nuclear power output is 62GW, which means you'd need 12h*62GW for simplistic optimistic night worth of energy. Which is 744GWh. But realistically you have to look at worst case scenario during long winter nights and cloudy days. Which is a lot more storage required and less solar power output. And batteries get degraded over time, some malfunction etc.
First, Nuclear power plants degrade much faster and at a higher cost than solar/batteries. Its the moving parts simplification. Its a major factor in why we replaced relays with transistors. Senond, you need to do some new research that reflects current technology. China will absolutely produce that amount of grid storage. Look up their production curve its insane.
Nuclear power plants can run many decades at full power with adequate maintenance, even more so newer ones. Can the li-ion batteries though? Note that they'd be under stress each day. Perhaps with new/different battery tech, but that's yet to see how it pans out. As per China and batteries, perhaps, but that's yet to see how it turns out at the end. They also reverted from not building (many) coal power plants and they are increasingly building them again. So, it's complex. Also read "China Targets 180 Gigawatts of Battery Storage by end of 2027" which is far away from minimum required for getting rid of nuclear and coal.
85% of the 180Gw capacity was installed in 2026. The machines to make that storage dont go away at the end of the year. Also the science on li-ion batteries is showing they degrade much lower than expected as well. All your data is out of date. Go read.
