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.

What about our technology? Our culture? Those aren't nearly as likely to survive, and a few handful of our species survival is meaningless without the above two.

And the dinosaurs are an example of a species that hasn't survived.

The fact that you seem to guarantee in your mind that humanity would survive is survivorship bias, I think? Or some other type of bias. Anyways. It's the same type of bias that religious people have in their minds, where they think the simple fact they happen to exist is just so improbable that there must be another factor at play to ensure their existence.
