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.

That would make sense if you were talking about a stable existing system of managed timberlands. When you convert virgin forest to managed timberlands, you are on net dumping a whole lot of CO2 into the atmosphere. And Canada is still doing that at scale.

No. As long as the timber isn't being burned, the CO2 is still in the wood.

The rain forest is being clear-cut for farming and those trees won't even come back.

The US doesn't even have to replant trees so they can potentially lose forests forever.

Then consider how much drier and hotter it's getting which causes forest fires to burn out of control. That's happening everywhere so CO2 is being released em masse.

But yeah, let's focus on how Canada's timber industry isn't perfect.

Hardly.

A big chunk ends up in slash piles because it's not marketable timber. Maybe 30% of the embedded carbon.

Another big chunk ends up as short-lifetime paper products, where it ends up back in the atmosphere.

More ends up as wood pellets to be burned.

Some residual amount ends up as long-lifetime products which keep the carbon out of the atmosphere.

Expansion of the area which is used for timber needs to end in Canada like it does everywhere else.

You can argue all you want but it seems you don't know much about Canada's lumber industry and I don't have the time or need to argue with a right-fighter.

I'm very confused by this statement; it sounds like you don't know the first thing how trees get used.
