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.

Whenever I see this, I always wonder - what effect does the change in atmospheric composition have on humans?
Directly, pollution is responsible for quite a surplus of deaths in densely populated areas.
Apart from that the CO2 isn't that much to have a significant effect on us.
Also microplastics, sadly.
People are dumber with higher CO2 concentrations. No joke bring a brilliant person and they will struggle. This is why we need good ventilation in classrooms because it can get stuffy(low O2 and high CO2)
How high of a ppm do you need to get that effect?
The government started pollution so people would get dumber and not question it

Making the atmosphere more akin to stuffy offices with bad air flow, mid-afternoon, but globally. Hmm.
What is the co2 ppm in a stuffy office I wonder.
Looked into this a while ago and I seem to recall 1000-2000ppm is “very stuffy office” territory.
(At one point I worked in a really terrible office and was considering trying to measure it somehow)
Looks like about 350 years till we get to 1000ppm at this rate. I'm guessing we'll die of being cooked before we get much dumber, but it's an interesting side effect.
Well here's the thing... There's a huge difference between levels where acute exposure causes something noticable, and living with exposure to something all the time
I teach at a secondary school in the UK, in a classroom with no external windows (but with air quality monitors). After 1 hour of 30 teenagers the co2 will be at around 2000-2500ppm which I can confirm is stuffy. Highest I've seen is in the next door classroom which made it up to 3800ppm back in the summer.
It really does make you (and the kids) feel really dopey, so not exactly ideal.
