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.

Last month was the warmest January on record globally.

It was also separately the warmest January for global land areas and the 2nd warmest for global ocean areas.

Hasn't almost every month been the warmest recorded in the past year?

Don't try to downplay this achievement. Companies all over the globe have worked very hard for it.

So are we just going to keep posting this every month until society collapses and most of us die within 10-20 years?

We're going to defund NOAA so it can't be posted and won't be real!

[–] NewNewAccount@lemmy.world 10 points 5 months ago

It’ll take longer that that and society won’t collapse without us experiencing some very painful death throes first. Gonna be a pretty wild ride. I feel bad for our children and their children most of all.

If covid and Trump have taught me anything it's that the majority of people aren't willing to do a damned thing until they themselves are hurt in some way. Based on this and my experience with peoples' unwillingness to admit they're wrong, I'd say we'll keep going until the majority of people tap-out from the heat.

In other words, we're just screwed.

Honestly, at this point, this sounds like the optimistic outlook.

The important question is what you (yes, you, the person reading this) are going to do.

The "this is fine" meme is all too accurate for posts like this.

As long as their line goes up, they don't give a fuck about the environment.

They can buy a new environment for themselves, their friends, and their loved ones. So it’s all good. If we didn’t want to die drowning in our homes, we shouldn’t have all bought cars and drank from plastic straws. Nobody forced us to do those things.

Hey ya know... Line must go up. 🤷🏼‍♂️

Climate change can’t be real cause it’s cold where I live right now >:(

Seriously hate saying it, but might not be a bad idea to move away from coastal and arid areas if you’ll still be alive in 30 years. There are tons of projection maps out there that show what your area will look like in a couple of decades if we don’t make serious changes. Still have hope that things will be better by then, but better safe than sorry.

I wonder what happens when you pour hot water in cold water.

Is that showing no negative anomaly years since about 1990?
