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, we need better/more diverse GMOs, lab grown meat, and vertical farming.

Or we can stop overengineering everything, stop raising meat livestock, stop growing cash crops in areas prone to drought, and go vegan.

There definitely needs to be better farming regulation to make it more sustainable, but that's really more of a California thing. Most countries are growing for sustenance, or have a rare viable climate for a crop like cocoa.

Developing countries need more efficient, more pathogen-resistant farming, which is where we need new technology like GMOs and eventually vertical farming.

As much as I hate recommending technical solutions to environmental problems, raising livestock for dairy, eggs, and meat has been a worldwide tradition for millennia, and I don't think it's practical to try to convince the entire world to go vegan. Lab grown meat solves this problem entirely, and once it's viable, we can ban all animal-based products in supermarkets.

Good luck with that. Also fuck no I'm not going vegan, wtf is wrong with you.

maybe just a little? Veggie fridays for funsies :) You don't need to join the church of veganology and shave your head.

PS: Lots of cultures on Earth are able to make a kick-ass meal with veggies e.g. Indians, Italians, Tex/Mex, Buddhists, Egyptians.

I want the populations of the planet, flora and fauna, to not die an agonizing death due to climate change. That's what is wrong with me.

Or, you know, we come up with a solution that will be likes by more than 5% of the population

[–] nyar@lemmy.world 2 points 3 months ago (1 children)

It's not a matter of what we like, it's a matter of what is necessary.

[–] phoenixz@lemmy.ca 1 points 3 months ago

Veganism is not necessary. Vegetarianism is not even necessary.

If you can get the energy from a CO2 neutral source, you can have artificial meat grown in factories.
