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.

"The hottest year on record".
This is becoming a joke, right?
Practically every year is the hottest on record now. It's kind of lost significance, when it's generally a good bet next year will be hotter.

  • 2010
  • 2014
  • 2015 / 2022
  • 2016
  • 2017
  • 2018 / 2021
  • 2019
  • 2020
  • 2023
  • 2024 (so far)
  • 2025 (probably)

Edited for clarity.

Is it?
Because "hottest year on record" doesn't indicate that at all.

there’s also the nice, easy to understand visual of the warming stripes

That's awesome!

It makes sense to say "the hottest year on record" if "practically every year is the hottest on record now" and you're talking about the most recent year.

Does it make more or less sense than "Another year of record breaking heat"?

"Hottest year on record" is like a child stopping on each step of a staircase saying, "I've never been this high!" It's correct, but doesn't mean much in context, and gets old real quick.

"If I take one more step, this'll be the farthest from home I've ever been."

Though unlike the hypothetical child or Samwise Gamgee, what we're doing is going to create suffering for very large numbers of people. It's probably also a reliable source of clicks for online media organizations.

Everything I come across says that 2023 was the hottest year on record so far, but I don’t know the source of this info and I’ve never seen the list you provided.

[–] Ranvier@sopuli.xyz 13 points 4 months ago

Yeah the person above you had a slightly old list. 2023 smashed all previous records and was number one. Well until 2024 it was number one I guess.

At this point, if I understand the data correctly, the planet would need to get dangerously cold for the remainder of the year to not go down as the hottest year on record

[–] Steve@communick.news 0 points 4 months ago (2 children)

I edited the list trying to make it more clear.

The point is, most years since 2014 have been "The hottest year on record." It's kind of lost significance as as an outlier, when it's generally a good bet next year will be hotter.

[–] petrescatraian@mstdn.ro 7 points 4 months ago (1 children)

@Steve It does sound geeky, but yes, it is technically correct to say about a year that is the hottest year on record.

And the fact you pointed that every single year becomes the hottest year on record makes it even more dangerous and shows that we need to take proper measures.

[–] Steve@communick.news 1 points 4 months ago

Exactly. We're on the same page.

[–] orca@orcas.enjoying.yachts 2 points 4 months ago

Yeah, it would be good to word it more precisely. Hearing the same phrase every year doesn’t have the impact they think it does. I’m kinda curious as to what would sound better 🤔

[–] shalafi@lemmy.world 3 points 4 months ago

Constant headlines about "the hottest ever" are getting stale. Takes the meaning out hearing it over and over and over.

Sounds like mom, "it's the hottest/coldest day of the summer/winter!" Yeah mom, it's the hottest or coldest day many, many times a year.

I'm also tired of, "smashed records!", when it was 1 or 2 degrees over the record.

Don't know how else to report it, but people are letting these headlines go in one ear and out the other. There's no real impact to the reader.

This dingus leaves off the source of his list AND the last two years

[–] Steve@communick.news 3 points 4 months ago (1 children)
[–] BrundleFly2077@sh.itjust.works 3 points 4 months ago

Infinitely so. I thought you were making literally the opposite point before the edit 🤣

You’re not a dingus.
