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.

Buckle up, it will get worse.

By how much is a human decision though. The bulk of coal, tar, oil, and gas are still in the the ground. There are forests yet standing. Cattle are the bulk of mammals.

We can choose to leave fossil fuels in the ground unburned. To manage forests to keep them around. To shift away from eating animals. Do those, and we can limit the damage.

[–] [email protected] 14 points 1 year ago (1 children)

Yes, we can choose to.

But those in power only care about money and power. And until they are dealt with or otherwise removed from said power, nothing is going to change.

We've already started to get change, even with the very limited and imperfect power that we have. Here's what is happening in the US:

[–] [email protected] 7 points 1 year ago (3 children)

The 2022 report shows a 0.8% increase for U.S. emissions. I get your point is that there are many plans to change that, but so far we're still going up and that's including offshoring some industries. That's why the world overall reached a new high. Granted the EU has made some progress, being I believe the only group showing a decline in emissions (-2.5%). As with any call for solar and wind (which was probably a key component) I have to ask if the environmental costs due to their manufacturing was worth it. I know, we have to do something...we sure can't look at the demand side of things though, can we? Always about how to make more energy with less bad effects.

Sorry...once you take the red pill it's hard to look at anything positive anymore. I used to think that way...

The 2022 report shows a 0.8% increase for U.S. emissions

Out of context sound bites like that achieve nothing but doomerism and serve those who want to make it worse.

The rise is to a level 3% lower than any year in 2012-2018 and 7.5% lower than the peak.

It's not enough, but it means we are starting to win, even if it's too late to save everything/everyone.

The 7.5% drop is also before what passes for the US centrist part started to take it seriously.

[–] [email protected] 1 points 1 year ago

Yes, there's a rise as a result of the decision to stop doing anything about COVID. It doesn't really change the trajectory driven by a piece of legislation which won't be fully in effect for a couple more years.

[–] [email protected] 1 points 1 year ago

South America also had a decline in emissions in the last two decades. Well North America as well, but coming from a high level. Africa is intresstingly having stable emissions since a decade, but given how poor the continent is that is likely to change. Really emissions growth comes from Asia and that is basicly it. It is countries like China, India, Vietnam and Indonesia becoming wealthy, which requires more energy. Obviously a lot of that is from fossil fuels.

However on a per capita bases the US is still among the worst and while Europe is better some countries are still bad.

It's a human decision as it's humans who can make this decision.

However it's a decision that only a very small minority of humans can do, most of us have no say in this.

[–] [email protected] 3 points 1 year ago

Most us aren't the final decisionmaker but have a lot of ways to out our thumb on the scale to influence the outcome

[–] [email protected] 6 points 1 year ago

Sounds kind of like "I had a liter of cyanide and only drank 1 cup of it,. Most of the cyanide is still in the bottle, so I should be fine if I don't drink the rest!"

[–] dustyData 5 points 1 year ago (1 children)

Even if we hit all the reduction goals as they stand now worldwide. We'll still deplete world oil and gas reservoirs between the century. The damage is done. Humanity made a decision about 120 years ago and we chose wrong. Even if we all died right now and all fossil fuel burning, industrial agriculture and extraction stopped all at once. It would still take the ecosphere a couple of centuries just to course correct, let alone return to the climate patterns of two centuries ago.

Let me tell you the quiet part out loud. Some rich countries individually might be hitting their climate goals. But worldwide overall we are way behind. So buckle up, it will get worse.

We're not where we need to be in order to limit warming to 2C, but we're doing a lot better than we were a decade ago, when it looked like 4C by 2100 was likely.

Has ~~humanity~~ our corporate overlords finally broken the climate?

“July has been the hottest month in human history and people around the world are suffering the consequences,” said Prof Piers Forster, of the University of Leeds, UK. “But this is what we expected at [this level] of warming. This will become the average summer in 10 years’ time unless the world cooperates and puts climate action top of the agenda.”

I'm sorry, but saying there's a chance to stabilize temperatures or prevent current conditions from becoming the new normal is irresponsible science journalism and straight up irresponsible science. Current conditions are the new normal and we're still pumping fuels.

Currently planned fossil fuel production vastly outpaces any climate goals. Impacts will become worse. They will not stabilize and they definitely won't get better than they currently are. (Super simple reference document: https://productiongap.org/2021report/ )

There's been zero discussion of canceling existing leases or restricting current extraction, let alone canceling and dealing with limits in production and available energy that would cause. There's been zero discussion of reallocating green sources to ensure food and fertilizer production to reduce food shortages and help feed people as production of consumer goods would be scaled way back without rampant fossil fuel usage there to drive it. There's been zero planning for what happens next.

We are driving headlong over a cliff.

We're still discussing recycling which has been proved to almost never actually occur.

No one is shutting down wells and mines. We are actively planning for destruction and devastation on a global scale and a complete collapse of ecosystems. It's fucking business as usual.


This guy, he's at least being honest:

“Knowing that we will look back on today’s extreme events as mild relative to what lies in our future is truly mind-boggling and hopefully serves as a wake-up call,” said Dutton. “The speed at which we make this transition will define the future that we get.”

Dude relax and look at all the profit.

/s

We had an okay run.

[–] [email protected] 2 points 1 year ago

There is the option, which you are describing of securing food supply, scale down of useless consumption and a strong roll out of low carbon power sources. That can be done, but nobody actually in charge even comes close to doing that, however in theory it would be possible.

[–] coffeebiscuit 19 points 1 year ago

Is this slowpoke news?

[–] TempleSquare 15 points 1 year ago

Until governments ban private jet travel, we just won't see serious public support. People struggling economically will fight back against taking on the brunt of the cuts.

Nobody actually wants to cut their carbon footprint, including well-meaning wealthy who advocate for change.

We're collectively in a heartbreaking devastating mess.

I hear we spent trillions of dollars on a climate bill. I been looking for solar jobs and theres nothing. DoE has like...2 administrative jobs.

[–] [email protected] 11 points 1 year ago* (last edited 1 year ago) (1 children)

You're looking in the wrong place then. Most of the jobs are in private industry; very few are in government.

[–] [email protected] 5 points 1 year ago (2 children)

Thats not the only place i looked.

[–] [email protected] 3 points 1 year ago

Tough to give a specific answer without knowing your location and full background, but I've seen a lot of people shift to working on or another piece of decarbonization in recent years

[–] [email protected] -3 points 1 year ago (1 children)

They’re not under the couch either

[–] [email protected] 2 points 1 year ago (1 children)

Found them.
They are in the coal industry

[–] [email protected] 3 points 1 year ago (1 children)

I’m sure you meant clean coal, right?

But I do know someone who works in solar panels installation in the US and says business is pretty good and firm has been growing!

[–] [email protected] 0 points 1 year ago* (last edited 1 year ago)

That's good to hear.

In Germany the jobs in the coal industry needed protection. At the same time the solar sector was reduced drastically over the last ten years and the jobs went abroad.

Edit: i don't know what you mean with "clean coal"
