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.

next up: why aren't millenials and zoomers having kids? probably because of avocado toast and pronoun.

Oh thank goodness, my youngest was born a year ago

[–] puppycat@lemmy.blahaj.zone 30 points 10 months ago (1 children)

mine was born yesterday, phew! imagine if they were born a day later!

[–] Yondoza@sh.itjust.works 4 points 10 months ago (2 children)

Congratulations (if this isn't a joke)!!! I'd love to help make the world habitable for your child.

[–] puppycat@lemmy.blahaj.zone 6 points 10 months ago

no I'm never having kids

unless the world somehow fixes itself and somehow guarantees it'll stay that way for more than a few seconds.

This has been clear for at least 20 years to anybody paying attention. I feel for those who will have to suffer this fate they didn't cause nor ask for.

In the 2000s they warned us the 2020s would be like this

They also said the 2050s would be apocalyptic

The craziest part is that things have blown past the worst scenario models, and many are still asleep. Or even worse, think some magical, undiscovered technology will save everyone. The outlook is pretty grim for anyone still around during the second half of the century.

Those 2050s are going to be coming sooner than expected.

We planted trees as kids in the 80s. Didn't just plant them either. We kept going back every year to check on the trees. We made sure that 10 trees for every kid in our school made it to 5 years before we stopped replanting that tree. Over the years I must have planted at least 50-100 trees. I wish it felt like it did anything.

[–] ILikeBoobies@lemmy.ca 3 points 10 months ago

I did similar though we didn’t check them ourselves

[–] veganpizza69@lemmy.vg 15 points 10 months ago

The current adult generations don't comprehend that they're sacrificing the children' future (and thus, the children) in order to maintain their Business As Usual lifestyle and dreams of being rich. It's all "what about me tho?", "it's someone else's problem", "it wasn't me!" All of this is very easy to do. It's like stealing ~~candy~~ potable water from a baby.

Well, the numbers are in and it looks like capitalism will be killing us all.

[–] hex_m_hell@slrpnk.net 1 points 10 months ago

It will not, but it will destroy everything it built and make capitalism impossible.

[–] ZILtoid1991@lemmy.world 4 points 10 months ago

Doesn't matter, the dominionists will blame it on trans people, gays, atheists, feminists, etc., and we will have to repent our sins to stop the second flood or whatever they will call the climate collapse.

Nobody knows the future, least of all some "study".

New people will be born, new technology will exist, new goals will be set.

I also think we are moving towards a bad future with no freedom and lots of censorship, with Ai, robots and implants, probably also world government and corruption.

I dont think the weather is going to be our worst problem. Its going to be ourselves.

[–] Genius@lemmy.zip 15 points 10 months ago (1 children)

The weather is going to be our worst problem in 50 years.

[–] andymouse@slrpnk.net 1 points 10 months ago

I suppose our second worst problem will be ourselves, reacting in our various ways to that worst problem.

Climate is not weather per se. Climate heating and chaos means that drinking water and food are going to become an issue; that's while you're taking in smoke pollution outdoors and sweltering indoors.

I'm not concerned with AI so much for the simple fact that electric grids, data centers and even chip production aren't going to do well in a hot and chaotic climate.

Some places have had more and more frequent heatwaves that lead to deaths in each year. And they are getting worse. Some ares in the world are having trouble growing food, dislocating people, and those areas are increasing in size. I can't recall the exact number, but I think by 2050 the US will have a very big problem when it comes to growing food.

[–] 1984@lemmy.today -3 points 10 months ago* (last edited 10 months ago)

Those estimates cant take into account new technology or developments that will happen during 25 years.

We will be alright. If we dont die in wars started by our dear so called "leaders".

[–] Shayeta@feddit.org 3 points 10 months ago

Where do you think most food comes from? Temperature controlled greenhouses?
