Is there a real practical solution to this? It seems like all proposed solutions in last 40 years are a drop in the ocean, or just a money grab scams. Only thing that really worked for such global scale is the ozone layer repair. Global warming/climate change I guess we should just accept it and adapt?

Yes, we got to adapt, we won't cool it down and "repair" what is broken.

However we can slow down the effects and try to stop the effects. So it's "only" 1.5° or whatever, not 3°, 5° or 10°. And if we raise average by 10° at least not by the years 2100, but 2200 to give time to adapt.

"Adapting" means resettling people, restructuring agriculture and food production, etc.

(All numbers are quite arbitrary picks, just as any goal one tried to set before)

I'm not sure what we should do, it's very hard to determine what minimizes harm and maximizes benefits at a global scale. It's certainly not as simple as extremists would like to believe. Certainly it would be much (MUCH) less risky to slow warming as much as possible and maintain constant or slowly reducing CO2 levels. I think from the standpoint of predicting what will happen, my best guess is that people will use…

Were you aware that the last time the planet was estimated to have co2 levels over 420ppm the global temperature was 10 degrees Celsius warmer overall? This is the global equilvant of being locked in a car in a sunlit parking lot.

Whenever you hear a politician say "carbon neutral by 2050", interrupt them. The real goal is to avoid getting too far over 1.5 degrees warming. We need to avoid reaching tipping points that will cause non-recoverable damage to the earth system. The year 2050 is meaningless. Actual global average temperatures is what should be measured.

A couple years back I saw articles about how we're basically less than a year from the tipping point. Then nothing. My guess is we passed the tipping point. It's inevitable by now.

February 29, 2024 - 2023 was the warmest year on Earth since direct observations began, and the first year to exceed 1.5 °C above our 1850-1900 average. ...

This isn't some big conspiracy. "On record" is since recordkeeping began in 1880. https://science.nasa.gov/earth/explore/earth-indicators/glob...

Ok, so why not just be specific? “On record” usually means since we started recording history , at least 5k years ago.

And have you looked into the records? satellite surface temps and high resolution recording have not been around for very long. 1880 methods were very crude and narrowly scoped.

Why: reduced albedo (less reflective clouds) because ships don't have so much sulphur in their fuel any more.

A change in attitudes is not enough. Structural change is needed to reduce our greenhouse gas emissions. Currently, the population is unable to achieve results.

The population is achieving results. Most of these results are occurring in China, which has begun an unimaginably huge deployment of renewables and nuclear. Europe is also making progress. The rest of Asia will go next, and then (as it develops industrially) so will Africa. Even parts of North America will quickly electrify: for example, Canada just agreed to reduce tariffs on Chinese EVs to 6% from 100%.

Uh, no, it’s the 3rd hottest year since 1880. You can click “Download Data” and look the table yourself. https://science.nasa.gov/earth/explore/earth-indicators/glob...

If you initially make factually wrong comment then you should at least apologize and say that you are sorry for being wrong, not keep pushing your agenda further.

I’m amused that the argument is that we are in a Mr Burns position where different kinds of pollution we were emitting was balancing out and somehow fighting pollution is the reason global warming is worse? While I’m sure it has some effect, the amount of co2 we pump out every year as a species is insane. The effect of ship pollution mitigating that is marginal at best

Stratospheric aerosol injection is the leading geoengineering proposal for a reason. If you have well-supported reasons to be skeptical, you should share it, but just saying "idk doesn't sound right to me" isn't convincing.

If we are in overshoot scenario even reducing emissions may not be enough. There are warming gases currently trapped in permafrost, the natural carbon storage capacity is very dynamic, so global warming may target new (worse) equilibrium beyond what we think we can achieve in best case scenario.
