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.

Why don’t you post more than that? Earth exists much longer than this. There are data about Earth temperature for hundreds of milions of years, but it probably doesn’t fit your theory, eg: https://www.climate.gov/sites/default/files/styles/full_width_620_original_image/public/graph-from-scott-wing-620px.png?itok=Jgi659bn
Has there ever been a period in Earth's history where CO2 concentration in the atmosphere changed this quickly without being accompanied by mass extinctions?
The Paleocene-Eocene thermal maximum is actually a great analogue for what we're currently experiencing. Huge increase in global temperature over a relatively short period of time, probably due to runaway methane release. It went back to normal within a few hundred thousand years because of increased planktonic CO2 sequestration in the expanded tropical zone.
