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.

"how forestry has been handled for centuries in northern Europe"

Clear cutting is a relatively new thing. It worsens the damages to forest growth from both drier summers and bug infestations, as the clearings don't provide shade or trap humidity in any way, and leave the trees on the edges of the clearings vulnerable to drying, weakening and thus more susceptible to bugs. The homogenous composition of wood farms also makes things very easy for bugs. The Nordic forestry model needs to change to one of continual growth for the sake of preserving both biodiversity and the climate.
