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.

Everyone knows, some deny, almost everyone does not care. Good night.

nah, I would say they don't know enough. Of course we heard about climate change for a long time now. But what does it mean? What are/will be the consequences? When?

I'm pretty sure that it isn't very well known that we'll have severe droughts, less food, climate refugees due to climate events damage, and that we only have less than 10 years left to act.

And then you have The Limits to Growth looming around the corner, around 2040...

People don't know enough, and that's why we need to speak to them.

The people in power know. The poor and middle class does not matter.

true, and that's why we should speak to them, because they vote.

Don't know where you live. We have some candidates in France, but we didn't vote for the right one. So right now we're fucked. But we shouldn't stop fighting.

The greens in Germany were voted for and made it into government. Massive onslaught and blaming since. All parties have declared the greens their arch enemies although they did not even start tackling climate change.

The internet exists, ignorance will not be bliss in 10 years.

I should have elaborated, there is no excuse for not knowing who represents your interests or at least claims to. The internet was designed and continues to be the most valuable research tool ever made. 10 years is the mostly agreed-upon timeline that we have to get our shit together.

The optimism in this case borders with being naive. We are so far into this crisis and yet our attitude to it could hardly be worse. The changes we would have to make to our lives get more and more profound with every month, and we are still putting them off.

[–] [email protected] 1 points 10 months ago

True, but at least we can partake in the upcoming chaos.

It pretty much all tipped back in the Industrial Revolution, and tipped much farther when nitrogen fertilizer began to be made directly from petroleum. At least if we care about original causes more than downstream effects.

Fertilizer is not made from petroleum.

You're right. I made a pretty ridiculous error of laziness writing "directly" when what I ought to have said was more along the lines of indirectly, essentially, etc. As far as I understand it, agriculture at its current scale requires a level of nitrogen input (via ammonia) that can only be supplied by the Haber process, which requires an amount of energy that we have no hope of generating by entirely renewable and sustainable means.

If you mean that there too many people on earth, you are wrong. We just use the resources unwisely. 62% of earths biomass is livestock.

99.9% of earths biomass is either humans, our livestock, or our pets. We are beyond fucked when the collapse starts.
