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.

They arent polluting far less than the US but it is less. Sadly this only shows 2000-2023, because that only shows Chinas major growth period where emissions went up overall. If you were to look at the last 5 years or so you would see they are actually reducing drastically and will probably never reach the pollution level of the US and keep improving much faster than the US.

I know the title says carbon tax, but there is a shit ton more pollutants than CO2. Anything done properly is doing to look at pollution. I was in Beijing once and holy fuck at the pollution.

Thats not what this post is about tho and that also doesnt have a global effect.

Well it basically is. And ozone layer, acid rain, mercury and plastics in the ocean, etc don't have a global effect? What's the new one, aluminum in satellites burning up destroying the ozone layer. It's funny that people have forgotten about pollution.

While I agree that we should be looking at other forms of pollution as well, I wonder why you're bringing China up in a discussion about Canada imposing a carbon tariff on the USA?

[–] [email protected] 3 points 1 week ago (1 children)

Seriously? Because we should be imposing pollution tariffs on everyone. Trade doesn't work so well when country A has strict environmental laws and country B doesn't. Example of the century: China.

We is Canada here? Yeah, they probably should, but that's not really relevant to this discussion, which is about Canada retaliating against US tariffs. This is not a discussion where China is relevant, because its about the US and Canada. I don't disagree with you from a policy standpoint, so I won't make any more responses, but relevance is important.

Sigh. All trade from every country in the world to every other country in the world should consider pollution. To have proper trade between all countries. In the world. All countries. Every single one. All of them.
