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.

MODERATORS
Those are the worst Freedom™ units. So hard to use and convert.
1 BTU = ~1.06 Joules
Yes but all of the derived units used in thermodynamic calculations. Pain in the ass to work with.
Heat Transfer Coefficients - BTU/(hr•ft2•°R) vs J/(m2•K)
Heat Capacity - BTU/°F vs J/K
Heat Flux - BTU/(hr•ft2) vs W/m2
Specific Heat Capacity - BTU/(lb•°F) vs J/(kg•K)
R-value - (°F•ft2•hr)/BTU vs (K•m2/W)
Thermal Conductivity - BTU/(hr•ft•°F) vs W/(m•K)
1 ton of refrigeration vs 3.517 kW
Just use gigaBTUs (GBTU) to get your metric fix.
