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.

07:00 - 1.5 by when?
08:04 - Shall we give up on 1.5?
09:17 - 1.5 is slipping out of reach

TL;DW: Probably not yet but we only have a handful of years to turn things around. Current modelling suggests that a 20 year average temperature for 2023 sits at about 1.26° C

In the business world, it is crucial to have defined goals. Thus makes it both fair and realistic people can agree on without the need to do something drastic like creating a dictatorship and pulling an ultron because we have to go it asap.
