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.

This is a really good example of why individuals can't make a difference, systemic changes are needed.

High speed trains when applicable, but there really isn't a practical way of going to Australia other than flying.

You don't like long boat trips in the Pacific?

Edit so there's a tradition of physical proximity for certain things, which don't make much sense with modern communication.

There's other things like research, physical work etc. we can make space for people to travel and make long term commitments to locale changes.

working on it

This is a really good example of why individuals can’t make a difference

Also defeatist and completely not true, billions of people are making an impact every day

But really meaningful differences are penalized instead of subsidised.

We need the conversation to go toward rewarding individuals who make sacrifices like this.

in australia we have stcs

essentially a discount on the renewables gear you buy

We have too much solar now in SA, check out the Price $/MWh:

and overall:

we also have lower interest rate home loans for people who add climate friendly renovations:

Nice, good job

Sustainable aviation fuel won't fix climate change, though. As long as the fuel is carbon based, CO2 will come out which fuels climate change

Electrical Aircraft are a BAD idea, no matter what muSSk says

We need to get electricity from renewable sources to use for industry, homes, and CO2 filters world wide, and likely let aircraft fly with carbon fuels, I don't see a viable alternative for that.

And on the carbon sequestration (CO2 filtering), please stop doing that now, it's not the right moment and quite literally only makes the problem worse. First get everything transitioned. Once that's done, then you can start sequestering and actually make a difference.

Link doesn’t say much but it’s still interesting. Wish there were affordable options. Most ships I see like cargo are $140 a day.

[–] [email protected] 6 points 1 week ago

$140 a day! I swear I have seen cheaper cruise rates.

[–] [email protected] 5 points 1 week ago (1 children)

Tf that would make crossing the Atlantic $1500

Might be worth it once just to say you did though

The Queen Mary II is around $850 going from NYC to the UK, though it only does so a handful of times per year.

[–] [email protected] 2 points 1 week ago

Cheaper than you'd expect, really.

Slow travel by boat seems pretty awesome and relaxing. Unless there is bad weather..
