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.

66% turnout rate in 2020 64% turnout rate in 2024

So about 8 million less voters. Let's assume there are all protest voters.

So less than 10% of non voters did so as a protest.

Thank you. 10% is a significant amount.

The bigger piece of the pie is the other 90%.

Statistically, 10% is significant.

That is not a phrase.

In the world of statistics anything over 5% is often considered statistically significant. How significant depends on context.

The phrase used in statistics is "p-values below 5% are significant".

This refers to uncertainty around a parameter value. Not the proportional sample size.
