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.

And summer will be Hell.

It sucks that the capital is on the East Coast, which saw slightly below average winter temperatures. Easy to pretend all is well when you can still throw a snowball, while the other half of the country is riding mountain bikes where they should be snowboarding.

Unfortunately the current government's axe man (Im not even saying that rat bastard's name) defunded and shut down every single weather and atmospheric observatory, so that none of the data from the sattelite observatories can be released, not to mention the last set of governments only giving lip service to 'meeting climate agreement goals'

At least they are not releasing fake data like they are doing on the economic front. Imagine sweltering in the March heat (???) and NOAA tell you it's barely 75 and the world is alright!

Much of the East Coast had an abnormally cold winter this year.

That's what made this winter special, the clear difference between the Rockies/West and the East was pretty stark.

The lowest so far! They are working hardly to break this record in der next years, as you can see by their efforts to contibute to the emission of greenhouse gases especially in the middel east /s

this is january news. it's almost april

[–] NihilsineNefas@slrpnk.net 8 points 3 days ago (2 children)

The top graph in the post shows March data, as does the link

[–] exasperation@lemmy.dbzer0.com 1 points 3 days ago

Why did you link a blog post from January, with January data, and then add your own March charts to this post? You probably shouldn't have linked to the external post the first place.

Yes... Now look at the black line. The one that's labeled as 2026.

[–] HeyThisIsntTheYMCA@lemmy.world -2 points 3 days ago* (last edited 3 days ago) (2 children)

that's red. it says january right next to it. do you need an ishihara?

[–] NihilsineNefas@slrpnk.net 3 points 3 days ago

This one. The one in the post.

[–] NihilsineNefas@slrpnk.net 2 points 3 days ago (1 children)

That's the wrong graph. Look for the one with all the pretty colours mate.

[–] HeyThisIsntTheYMCA@lemmy.world -2 points 3 days ago (2 children)

not clicking on a link if you can't figure out the right month dude.

[–] NihilsineNefas@slrpnk.net 2 points 3 days ago

And just in case you're still scared of links. Heres the graph showing updated information, the line in BLUE is this year.

[–] NihilsineNefas@slrpnk.net 2 points 3 days ago (1 children)

I'm not the one who can't even read a graph.

But here, just in case you change your mind here's an interactive map with an extra graph that provided the original data for the graph

oh wow you get worked up over someone not caring about your post.

[–] NihilsineNefas@slrpnk.net 1 points 3 days ago

For someone that "doesn't care" you sure do comment a lot.

La AEMT falla cuando estima ergo el cambio climático es una patraña. Que me lo ha dicho mi cuñao de Vox

[–] NihilsineNefas@slrpnk.net 3 points 3 days ago

They're right, the only people that think it's a hoax aren't brave enough or smart enough to look at the data that the world is putting out and see the changes happening in front of our eyes.

Ok, but overlay El Nino years to get a perspective because those are usually the dry, cold years.
