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.

So why did they elect a dedicated climate denier to run said US?

Well we sure don’t fucking vote like it.

People dont usually change their votes when they dont agree on 1 thing

Maybe they dont like global warming, but they dont want to vote for someone who wants to turn kids trans with evil Antarctic lazers

Don't know 'bout you, but I did.

They absolutely do not support this in any meaningful way. Try telling them they have to get rid of their car and stop flying, and that in the meantime gas prices will shoot upwards, and then let's see how much they actually support this. They just said they supported it in a poll either because they thought that's what they were meant to say, or because they didn't understand the implications of what they were agreeing to

A managed phase out with viable replacements for transport and heating is very different from getting rid of stuff today

That misunderstands the problem of climate change.

A managed phase out was a solution 20-30 years ago, nothing but drastic change can work now. After about 2c (or thereabouts) theres no meaningful way of coming back from tipping points and civilisations lost from there. We're likely to have emitted enough for 2c to be locked in, in about 4 or 5 years.

We need a 10% emissions cut per annum, at keast and more to be cautious, that means ditching low hanging fruit now, like no flying, no cruise ships, no personal jets, no water craft, cut defence expenditure by 50% etc, so harder stuff, like closing roads and car parks and buildibg medium density small homes to house those from the needed managed abandonment of places like Miami, Las Vegas, Phoenix etal using the sliver of emissons budget left

Incremetalism is just denail wrapped in a diffent colored shroud, that's whats getting nothing done now as emissons keep increasing.

What most people think needs doing is a few solar panels and ecars when they get aroubd to it i.e the ones surveyed, what needs doing is the complete reworking of the political and economic systems we live under, likely dissolving nation states etc.

Now we can do this in a hectic, best we can kind of way ... or ... nature will do it for us and it will be beyond traumatic but it will happen.

10% per annum are also increments.

Yea good luck with phasing out current infrastructure when local council meetings are full of loud NIMBYs.

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

Agreed. And also, there are places where the only alternative is expensive electric cars, and also there is little or no charging infrastructure in place. Nationwide, we're nowhere near ready.

They should have thought about that LAST month.

hating and hurting their neighbors, and friends, and even family members, is more important to them than saving the planet.
