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 charts are using primary energy? the only useful metric is energy we can actually use, and all statistics I know generally compare emissions per kWh of electricity, not primary energy.
We don't take inti account the energy of the sun for calculating solar energy either.
The ones I've seen people using in online discourse are these which mislead the heck out of people trying to figure out how much work is needed for displacing fossil fuels.
Oh wow, that is terrible and disapointing. Then again, when you think about it, it does mean the corrected graph gives us more hope.
huh, interesting!
If we did then solar energy would be the most ridiculously inefficient energy source on Earth. Only 0.000000045% of the Sun's energy even hits Earth at all.
Though now that I think of it, uranium comes from supernovae and neutron star mergers. So nuclear power might be even less efficient.
If you look around, there are tons of people who claim that all of the primary energy used today needs to be provided by renewables in the future (and that that's impossible).
