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.

That will lead to world war.

nevermind satellites, just diff the temp records from say, 1950-2000 and the ones reporting that data today and there's a lot of jank. urbanization around the thermometers also makes it appear as though global temperatures are rising, but all the data really says is that cities are heat islands. first order: verify satellite data. Secondly, move all sensors to locations where they are unaffected by heat islanding and…

Where are you finding where all the sensors locations are?

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.

Even if we stop all emissions right now, we'll exceed the 1.5C target, so...

The nice thing with climate change is that it can always get worse !

If we miss the 1.5 target then the next target is 1.51. And so on.

That goal is no longer possible.

I agree that staying below 1.5°C is extremely unlikely at this point. But it is still worthwhile to try to keep it under 1.6°C.

My point is that in terms of personal responsibility nothing comes remotely close to driving but a vanishingly small proportion of people are willing to consider this.

A few decades ago we explained that personal responsibility isn’t the solution. Please catch up. Why we’re having a conversation from the year 2000 now is beyond me. I also suggest reviewing the “nuclear isn’t part of the solution. Besides it takes a decade” discussion.

How does cultural change happen?

I would say it's often because people see individual examples in action. Some people follow those examples. Then more do. You are more influential than you think.

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?

Drive less. CO2 output per person in the US (all sources including industry, etc): ~13-14,000kg Average distance driven per year per capita in the US: ~20,000km Average CO2 output of current private vehicle fleet: ~250g/km Therefore, over one third of total CO2 output per person is personal vehicle use. Considering only CO2 output due to personal choices driving has to be well over half. Most people don't - or refuse…

love how a completely valid point gets downvoted becuase the average person refuses to believe they are part of the problem "no! its those big corporations and airline industry! my daily commute has no input at all!"

and this is why we'll never solve the problem

Even if it were meaningful, is the proposal to fight global warming to keep dirty ships? That’s an insane strategy. More realistically, there’s vested interests in existing ships and shipyards not being made obsolete so any minute effect is overhyped as “this is how we solve global warming”. This reminds me of a conversation I had with an acquaintance - he was convinced that anthropogenic global warming was impossibl…

"Less bad" is still better than "worse"

You want to unthinkingly reject a proposal that makes things better because you can't understand the third order effects and refuse to accept any evidence.

The Doomerist paralysis has been engineered by the folks who look to benefit the most from inaction, mainly the fossil fuel and related industries.

To not even attempt to head for the lifeboats is suicide.

I know I sound like a broken radio, but:

Google "urban heat island effect site:realclimate.org"

Scientists have been aware of the effect and correcting for it since before you heard about it. In general, if you can think of something in five minutes, scientists (whose lifetime job is to consider these problems) have considered that.

The proposal is the spray purpose made reflective aerosols high in the atmosphere.

We almost certainly will end up doing this, negatives be damned. Even worse it's just a bandaid not a fix.
