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.

With its vast expanses of forest, Canada has the most “certified” sustainable timber operations of any nation, according to the nonprofit organizations that attest to the environmental soundness of logging practices.

Such forestry-standards groups were born in the 1990s out of rage over tropical rainforest destruction. Today, they put their leafy seals of approval on toilet paper, two-by-fours and other wood and paper goods to assure eco-conscious consumers and investors they were responsibly produced.

Yet research shows Canadian forests have seen some of the world’s largest declines in ecologically critical primary and old-growth woodlands over the last two decades, even as sustainability-certification programs grew to include nearly all of Canada’s logging.

To track destruction of older woodlands in these certified zones, Reuters analyzed forestry data in Ontario, a major logging province. The analysis found that about 30% of the certified boreal forests harvested from 2016 to 2020 were at least 100 years old. That resulted in the loss of 377 square miles of these older forests, an area the size of New York City and Washington D.C. combined, the analysis found.

I've gotten so cynical about the "sustainable" label that I pretty much assume any product, company, etc. that claims to be sustainable is probably the exact opposite.

I am not sure which is worst. The ones that don't care at all or the ones that outright lie about caring. :(
