It's almost as if the globe is warming. We should think of a term for this phenomenon.
Climate
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.
What if we stopped using oil cold turkey? Sure, still wouldn't reverse things immediately, but sure as heck wouldn't continue to make things worse....
Coal, oil, and gas, all three need to be stopped. They are the bulk of the problem, but not all of it; we also need to end some industrial chemicals like SF₆ stop deforestation, and sharply reduce methane production in agriculture.
Cold turkey will kill a lot of people as existing food systems depend on fossil fuels for everything from nitrate fertilizer manufacturing to food delivery.
A managed phase-out is far preferable because of that.
Stopping meat and dairy would instantly take care of deforestation, methane excess, and fertilizer shortages, and it would free up a massive amount of logistical capacity. Most of our agriculture is dedicated to feeding farm animals, mostly with stuff we could eat too.
This could be done cold turkey in literal hours, redirecting soybean shipments from factory farms to groceries and letting everything else collapse abruptly.
That at least is physically possible. Its also well under half the problem. So things get worse a bit more slowly if that’s all we do. It takes a lot more to actually stabilize temperatures
The proper handling of municiple waste (not direct sewage application) could easily replace fossil fertilizers and ramp up time could be 3 weeks if the right process is used, so the fossil argument that a lot of people will die is really just a death cult hopeful excuse for mayhem and destruction. A good cover. But here we are - 2026 and tRump is still somehow inexplicably in office, trampling the constitution and citizens rights...... It's possible this particular end is deserved 😓
It is really possible to mess this one up, and that's only one of many places fossil fuels are used in agriculture
