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.

We were supposed to hit peak emissions. Why won’t they stop rising? (www.vox.com)

I get that you have hope, but magical thinking isn't going to fix this unless you are literally capable of magic or you have a time machine powered by positive thoughts or something.

We are already globally over capacity on fresh water. Crops are already failing. The earth is already at heat storage capacity. Carbon emissions are still rising. Population numbers are still rising. Capitalist industry is still posting record profits.

Most people won't even consider a vegan diet and campaigning for community gardens and bike lanes isn't going to magically increase the heat storage capacity of the oceans.

So I am genuinely asking you, mitigation of resourse depletion, works how? Mitigation of thermodynamics works how?

What type of hard work do you think can fix this?

Accusing me of magical thinking and then elaborating on or reiterating your point sort of closes the door on this discussion.

I could copy and paste a bunch of stuff, add a bunch of links. I don’t think it would bring us closer.

The scientific consensus (as I understand it and you’ve yet to convince me otherwise) is that global freshwater supplies are unevenly distributed but far from depleting; crop failures are regional and gradually being mitigated by advances in agriculture; oceans can still continue absorbing heat with severe ecosystem impacts, but there isn’t any reason to use language like “full capacity” limits unless you’re misrepresenting the facts to scare people; population growth is slowing, with consumption patterns, not numbers, driving resource strains.

I want to reiterate: you are not helping the issue by telling people the end is nigh. You’re also not being honest, so long as you’re claiming to have kept abreast of the way experts in these fields are talking.
