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.

27,000 deaths a day approximately. According to the WHO 150,000 people die every day right now. 385,000 people are born every day. I mean it sounds bad, but in this context it doesn't sound that bad....

Exactly, and it's not like it's going to be me dying. It will be someone else. Thanks to denial, I'm immortal.

Don't look up

[–] ConfuzedAZ@lemmy.world 1 points 1 year ago

Yeah, honestly I think the estimate may be low, or perhaps white the death toll is not what is expected the actual quality of life is going to take a huge bit.

@ConfuzedAZ "385,000 people are born every day"

For now

[–] ConfuzedAZ@lemmy.world 5 points 1 year ago (1 children)

Yeah. Don't blame people at all for not having kids. Frankly the planet probably needs less humans.

[–] Alto@kbin.social 4 points 1 year ago (1 children)

The planet can absolutely support more humans.

We'd just have to be something that even halfway resembles responsible about it. Good luck with that part

The planet can absolutely support more humans.

As the world becomes more industrialized and its citizens desire more of the "first world life", I'm starting to be wary of that view.

Causing 15% of deaths is a big deal. Maybe not as much a big deal as Doomsday Next Tuesday, but a big deal nevertheless.

You cannot compare this number and the current population. It's not the same unit. We have humans/time and humans.

I can't imagine that birth rate keeping up much longer.
