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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

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
