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.

They differ in the details slightly, accounting for performance differences. But every time the interests of the asset class conflicts with the interests of the consumer class, they both make sure the asset class is happy.

Whenever I see affect I think of people making faces. And any single economic decision effects people, while the economy as a whole affects people. With my phrasing I can see either works.

Affect is a verb: the rising grocery and gas prices are affecting my spending choices.

Effect is a noun: the effect of rising grocery and gas prices are changing my spending choices

In your example: any single economic decision has an effect on people, while the economy as a whole affects people.

Except when affect is a noun (disposition or emotion) and effect is a verb (to bring about or make happen).

Just to make things more difficult. :)
