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.

We got here not by one big move. It took a long time, poor information and many small choices. Companies made money by convincing people to be unthinking consumers. On macro scale, you cannot do much except be informed and vote. If everybody bought green, corporations would have to follow the consumer's spending habits to make profits.
On a personal level, you can grow a garden, plant edible landscape and edible perennials wherever you can. You can buy the most efficient and durable cars, appliances and clothes. If possible, you can choose live in areas that do not depend on massive use of energy for heating or cooling.
