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.

That isn't entirely true. At lower speeds there may be other inefficiencies that are worse than wind resistance (since wind resistance becomes negligible at low speeds).
It will depend on the vehicle, but for example, small gasoline cars are more efficient at ~70 km/h than at lower speeds. Electric vehicles will likely be more efficient at lower speeds (~40 km/h) than gas vehicles, due to (lack of) gearing but there will still be low speeds where they are less efficient than higher speeds.
