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.

Just copying my comment from another post about the same article:

Even in the past 3 years there has been a noticeable decline. We moved 4 years ago to where we now live. The first spring and summer the place was buzzing with insects. We actually made the entire garden much more insect friendly but last year there were noticeably less than the previous year and this year it's just dire. In april I walked around our back garden which was full with flowers and I had to stay in one spot for several minutes before I spotted the first bee. I am incredibly worried and depressed from this. It's horrifying.
