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.

It makes sense to say "the hottest year on record" if "practically every year is the hottest on record now" and you're talking about the most recent year.

Does it make more or less sense than "Another year of record breaking heat"?

"Hottest year on record" is like a child stopping on each step of a staircase saying, "I've never been this high!" It's correct, but doesn't mean much in context, and gets old real quick.

"If I take one more step, this'll be the farthest from home I've ever been."

Though unlike the hypothetical child or Samwise Gamgee, what we're doing is going to create suffering for very large numbers of people. It's probably also a reliable source of clicks for online media organizations.
