Re: Climate change is not just about Carbon Dioxide

The trouble with the climate change lobby (aside from the paid /lobbyists/ and entrenched profit motives) is that you can only cry wolf so many times and make so many wildly hyperbolic and/or hypocritical claims before well-intentioned people start to question the whole narrative. Don't get me wrong - I'd prefer not to find out what sort of negative impact climate change may have. I just think the current messaging i…

There has been no crying wolf. If anything the dangers are being consistently undersold. Just because someone says 'it will be x bad if you don't do this list of things' then you do three of them and ignore the rest and it's not quite as bad doesn't make them a liar.

> There has been no crying wolf.

... In your opinion. Perhaps we could agree on the term "moving of goalposts" instead. A skeptic might ask how the dangers are being undersold and how you know those dangers are legitimate as opposed to inflated claims made by those who earn money through making them. Again, I'm not saying I don't have my concerns - or that I'm not doing more than most to minimize my impact. I just think the doomsayers aren't necessarily entirely correct, without blindspots or without bias. To think otherwise seems naive.

Earlier quoted context omitted.

And what do you propose as an alternative? We've known about climate change for over thirty years and there's been no real substantive action nor any decline in atmospheric CO2 levels.

Discuss the actual predictions from mainstream climate science rather than the unlikely doomsday scenarios, like a hothouse Earth. And include the adaptability of humans and the potential of technological solutions. Weigh that against realistic scenarios in a cost/benefit analysis. Proclaiming society is doomed and humanity is going extinct is not only unlikely, it’s chicken little and ends up turning well meaning pe…

We’ve done all of that. Have you looked for it?

I have seen it, which is why I mention it. So no reason for the sky is falling bullshit doomerism. That accomplishes nothing.

The whole papers revolves around this claim:

> Marine plants like diatoms produce omega 3 oil which acts like a cap on the surface of the water to slow down evaporation

There are no numbers about this, no reference, nothing. And this claim is quite extraordinary. This absolutely needs to be quantified in order to go further. How does omega 3 oil, rejected by sea life on a limited portion of the sea, a product that can be oxidized easily, be a significant barrier to evaporation.

Maybe this is true, I don't know. But this is definitely counter intuitive and any counter intuitive claim should be supported by something, not just hand waived like that.

Does anyone have references for these claims? Particularly: > pH will drop to pH7.95 by 2045, and most marine life in our oceans dissolve.

pH could drop to 7.95 by mid-century, according to the latest projections: https://bg.copernicus.org/articles/17/3439/2020/ . The second part of the sentence seems fictional. I don't think there is any support of that from a basic understanding of carbonate chemistry.

Found something that could in fact trigger mass extinction due to acidification [0,1], however not on the stated timeline.
