‘Climate change is here’: Experts warn global crisis is decades ahead of forecasts
(www.independent.co.uk)
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.
If a country made green tech free, the United States would organize a coup to restore fascism or some other capitalist order loyal to the US.
The world lives in fear of the US military-industrial complex. Even the USSR and China are/were defined by their relationship to the US. The USSR existing under embargo and struggling to support a sufficient military to ward off the US, and China only becoming a comparable power to the US by letting itself become the industrial heart of capitalism for over 50 years.
I am not saying that all the world's woes are the US' fault, I'm saying that ever there is a place in the world without woe, the US is there to rectify that existential threat to its hegemony.
Maybe after the US has finished committing murder-suicide by fascism, those of us who are still alive can start building for the future rather than for profit without fear.
The US is much more fragile than it seems. It was able to dominate the world by leveraging control of oil and currency to maintain the internal caste system. Fascism is expensive though, and it's already choking.
Genocide is a last gasp to maintain power. There is no way to prevent revolution, so the right is flailing. They believe that if they reestablish the "demographic distribution" that existed at their height, they can maintain power. Basically, they think they can ethnically cleanse the US back to the right. But that can't work. Nothing can possibly work because it's all over for them. So yeah, the US isn't going to last much longer... Especially now that they've nuked the soft power they used for so long to keep everything in check.
