I wonder what would happen if we started measuring the carbon emissions for multinational supply chains..
As oceans warm, great white sharks are overheating

#32How come the sharks don’t migrate toward colder water?
> Several large tuna species and sharks, known as “mesothermic” species for the way their bodies run hot, require more fuel to maintain their temperature and are thus confronting a “double jeopardy” of warming oceans and declining food, mainly from overfishing. As water temperatures climb, these species will be forced to relocate to cooler waters.
They are moving to cooler waters but the cooler waters won't have the food supplies they need. So it's either stay where the food is and overheat or go to cooler water and starve.

Carbon emissions from food production may go down about that much. However, those emissions are only about 30% of the total CO2 emissions humans are responsible for, if I recall correctly. So, total CO2 reduction would be about 18%.
and likely other un predictable knock on effects would reduce the benefit, like going vegan would mean more food is available overall, and population might rise in response.
Maybe. Due to not just the caloric availability, but due to eating habits that may influence behavior.

#36My main skepticism (Shark lover here btw!)
Is that sharks are an ancient species and they’ve survived way warmer oceans even relatively recently.
For example the Medieval Warm Period Sargasso Sea surface temperatures were 1°C warmer than 400 years ago, and Pacific Ocean water temperatures were 0.65°C warmer than the decades before.

#37- stupid question - if everyone on the entire planet went 100% vegan from tomorrow, will carbon emissions really go down by 60%?
Most of the emissions are done by the 100 biggest corporations. That's where I'd start fixing things.
That’s basically a different way of measuring the same thing. These corporations don’t just exist in a bubble, many of them are going to be behind the food production either directly or indirectly (e.g. energy companies providing fuel for machinery).
Food is responsible for about a quarter of greenhouse gas emissions[1]. I agree that it’s not realistic to assume this will be solved individually, more pressure needs to be put on these large corporations from governments, but the quickest way you or I can make our own (individually small, collectively large) impact is by cutting out meat from our diet (specifically beef[2]). We are end-consumers of those 100 largest corporations one way or another.
(Not a vegetarian/vegan btw. I’m not trying to shame, I’m certainly not perfect! I just wanted to share the info that it’s not someone else’s problem. We’re all in this together)

This comment makes me so, so angry. Like, shouting angry. It's a person who hasn't engaged with a topic AT ALL except to find one headline that downplays the concerns of others. It's the quintessential bad faith comment, created of willful malice or ignorance (and I don't mean that be aggressive, but descriptive). Which is more true: are you trying to comfort yourself with this comment, or do you find those who work…

Another bad-faith contribution, a snarky comment befitting of a default subreddit. Doesn't even logically build from what I posted, nowhere have I committed the "appeal to authority" logical fallacy, but you have made the leap.
And for what? Why? Ideological reasons? A sincerely held belief that the extinction probability of polar bears is dramatically overstated based on some insight that doesn't seem to broadly available?

I’m not following. I understood the original claim to be that we can’t question the polar bear narrative. Did I misunderstand?

Ah, then I would like to apologize.
I interpreted your comment as a snarky response to me, not actually imploring others to trust those dedicated their lives to understanding the issue. Perhaps I'm too primed on this subject to assume bad-faith engagement because that's so often what I get. That's more about me than you.
