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.

"Silent" killer that scientists have been loudly warning about for over 40 years now

[–] killernova 5 points 1 year ago

Scientists have been loudly warning us about greenhouse gasses for over 200 years. We didn't listen, still are not listening, and this is the result that has been predicted for centuries. Many more people will die, as required, all for some pieces of paper monopoly money that we just made up and pretend has value. Humanity is so special!

It's not silent because we don't know about it

It's silent because it's literally silent. You can walk by someone dying from heat exposure and not really notice they're dying. The person might not even realize how dangerous it is.

Compare that to a stroke or heart attack and it makes sense why this is called a "silent killer".
