Climate - truthful information about climate, related activism and politics.

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.

You just kinda linked to the IPCC website. Care to expand on what you’re hoping I get from that

[–] troed@fedia.io -4 points 2 weeks ago (1 children)

I linked the AR6 report since you haven't read it.

lol okay

So tell me: is this the one scientific paper about the effects of climate change that somehow found the rise in global temperature as we continue to release co2 and methane into the air doesn’t increase the drought conditions, extreme heat, more powerful and deadly storms, loss of crops? Because you being so smart having read this study, it must be something new, right? Not exactly what scientists have been saying for decades? This one study on this subject must be completely groundbreaking and not relaying the information that has been found in all the other studies, correct? I mean, obviously it is, because it’s found that extreme weather events, sea level rise, and a dying planet bringing acidified oceans and untenable land and drought (and the concurrent famine) aren’t the results of our actions…right?

Are you refering to IPCC AR6 as "one scientific paper"?

... and getting upvotes?

I mean. Peak stupidity.

Jeezus. You’re really trying to argue semantics instead of defending your position? You know “AR6” stands for “sixth assessment report,” right? They accumulated a bunch of papers, and made…a report on the findings.

But since you’re clearly so much smarter than everyone and read so much more than us, why don’t you enlighten us all on these brand new findings that you know everything about? Did they or did they not find that human emissions are causing increasingly dangerous conditions? So please, pass your infinite wisdom to us peons. Grace us with your genius! Because you seem to be implying that they didn’t—more than that, you’re straight up claiming that they didn’t. Are you sure you read it?

IPCC AR6 is the scientific consensus regarding climate science, and no, it does not support your doomism.

You've never read it.

[–] sneaky@r.nf 2 points 2 weeks ago

Not OP and I've never read it. Can you expand on the point of the paper and it's content?

[–] TheFriar@lemm.ee 1 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

lol and yet you refuse to expand on it. I’m really starting to believe you’ve never read it.

Here’s the synthesis:

  • Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020. Global greenhouse gas emissions have continued to increase, with unequal historical and ongoing contributions arising from unsustainable energy use, land use and land-use change, lifestyles and patterns of consumption and production across regions, between and within countries, and among individuals."
  • "Continued greenhouse gas emissions will lead to increasing global warming, with the best estimate of reaching 1.5°C in the near term in considered scenarios and modelled pathways. Every increment of global warming will intensify multiple and concurrent hazards (high confidence). Deep, rapid, and sustained reductions in greenhouse gas emissions would lead to a discernible slowdown in global warming within around two decades, and also to discernible changes in atmospheric composition within a few years (high confidence)."
  • "Climate change is a threat to human well-being and planetary health (very high confidence). There is a rapidly closing window of opportunity to secure a liveable and sustainable future for all (very high confidence)."

Note that last bullet point. The words may be different, but trying to tell me that human caused climate change is not an active and increasing threat to human life is beyond absurd. “There is a rapidly closing window of opportunity to secure a liveable…future.

Do you know what they’re saying? Why are you trying to dampen the reality of the threat or continued emissions? Are you literally just some shitty shill to say we’re all fine and nothing is happening?

lol

You're the one that claimed stuff not supported by the IPCC reports. Now trying to pin your random hallucinations on me won't cut it.

The world is not actively murdering us. That was your claim. If we don't cut emissions we will get into problems with changing growing regions for crops, need to move away from current sea level infrastructure and most of all we'll see wars raging when we don't allow people to move with the changing climate zones due to national borders.

Try reading the appropriate Working Group section instead of the summaries. You might even learn something.

“When the world is actively murdering us, maybe we’ll finally see some positive change for a few select oppressed groups.”

This is all over an off-the-cuff joke. About how in the future, “when the world is actively murdering us” we’ll see a modicum of positive change for some groups of people.

And you’re trying to say this is not something that is increasing in likelihood because the IPCC says it’s not going to happen? Like…are you alright? You still haven’t shared a shred of data that supports your claim. Jesus, I shared more from the report than you have. And you’re like, “no. Not that part.”
