Climate - truthful information about climate, related activism and politics.

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.

Correct. Paper (PS: or at least brown cardboard), glass and alu will always be great candidates for recycling.

Aluminum is the poster child for recycling, really. It takes more energy to extract it from the ore than it is to recycle it.

I was under the impression that the chemicals involved in recycling paper products, combined with the fact that virgin paper is almost entirely sourced from managed, quick-growing tree farms, make paper recycling also undesirable?

Have heard similar things. And it's also true that timber farming is a (very marginal) form of carbon drawdown, assuming the wood products are not burned. But then in theory recycling could allow some of that land to return to nature, which better in all ways. It's a systems problem.

The chemical issue is presumably bleaching for white paper. But thick brown cardboard is basically just degraded wood fiber so that at least must be pretty efficient to downcycle into toilet paper.

Update: there's also another chemical issue in de-inking, maybe that's what you were referring to. Personally I don't bother recycling my tiny amounts of paper waste, for these reasons. Thick cardboard must be a win though.
