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.

Why Climate Goals Aren’t a Lost Cause—Even If We Overshoot Them | Earth will likely warm by more than 1.5 degrees Celsius, but we can’t give up on trying to get temperatures back down (www.scientificamerican.com)

The key thing here is that the less overshoot the better, and the amount of overshoot we can afford is small.

"Even if we 1.5C" DUDE WE JUST DID CAN YOU NOT READ

Yes we know we've got to do everything we can but it everyone in power decides to sacrifice us all for wealth the only option is global revolution and, uh, hit me

Considering that I have by now met several "the world is fucked anyway, so just let me drive my car and do whatever I want"-people, I guess article (headline)s like these make sense to have.

some pretty freeing schools of thought that allow people to think this way, it would literally eat at me acting this way … but I wish I could have that bliss sometimes

Encouraging that is a really deliberate thing by the fossil fuels industry.

getting to drawdown a year sooner would be like ending the Holocaust a year sooner. it should be obviously worthwhile.

[–] HubertManne@piefed.social 6 points 1 day ago

Its sorta duh. Most of the doomers were just about reality but only idiots take the give up path. Every year for the rest of your life and if you have them childrens or other relatives lives will be worse the less we try. Not to mention much of what we can do is part of making a new normal that deals with it better so its sorta a double return. Im talking insulation, thermal mass, geothermal, solar, wind, etc. Its not just about green its about comfort in the short term to.

the path it will actually take:

Its on us to prevent that

[–] collapse_already@lemmy.ml 6 points 1 day ago (2 children)

No one with any political power is even remotely trying to prevent that. Maybe we can have a huge war that kills billions to slow the rate of ascent. It is the most likely path that actually results in a timely emissions reduction that is politically tenable (see Iran v. Israel and Pakistan v. India for potential starting points, Ukraine v. Russia could escalate too, I suppose).

More likely, the climate will start killing us in greater quantities (famines, floods, hurricanes, droughts) resulting in an emission reduction. Eventually, it is a self correcting problem, but that most likely outcome maximizes suffering.

Well Iran vs Israel is already happening and escalating into probably a forever war but I doubt war will help climate change War itself also causes a fuck ton of emissions and environmental damage

[–] collapse_already@lemmy.ml 1 points 6 hours ago

It hasn't really ramped up to anywhere near the levels I am talking about yet. I am looking at it from a perspective of WW3 woth billions dead before it lowers carbon emissions. Pretty that carbon will not be our worst concern among all of the fallout.

Xi seems to be putting China on a decarbonization trajectory. Not as fast as we need, but one that's meaningful
