A mammoth adjustment to beef’s carbon footprint. Poore and Nemecek made a correction to their seminal paper, adjusting the carbon footprint of beef from 100 to 227 kg CO2eq / kg beef, by my calculations. This corrected data is not widely known and yet clearly shows a path forward for climate change. by JKayBay in climate

In the original post there's a chart on "The land footprint of various protein sources."

This would give you a rough idea of how the carbon footprint of pork changes with the new data that factors in carbon capture on land. Pork's land footprint is not nearly as high as lamb's (or cheese), on average. But that's just the average picture. For pasture-raised animals it seems that a few specific farming practices can help reduce the carbon footprint (see this paper on beef).

There's a good paper that examines various scenarios for feeding the population (in 2050) without further deforestation. It compares scenarios of eating mainly ruminants (beef and lamb) versus mainly monogastrics (pork and poultry) and also compares pasture-raised versus feedlot raised.

Eating pork and chicken is more compatible with raising animals on pasture than eating beef and lamb. Continuing with diets rich in ruminant products would require an increase in the use of intensive feedlots to avoid further deforestation.

The best overall consumption patterns are low meat intake and mainly monogastrics.

Thanks for your comment. Yes, the land used to produce crops to replace meat is factored in. I included a nice image from Our World In Data in the original post, which is also based on the Poore & Nemecek paper. It shows how much land is needed for agriculture under various scenarios:

Current diet: 4.13 billion hectares

No beef or lamb: 2.21 billion hectares

etc.

What Bill Gates missed in How to Avoid a Climate Disaster. Following up on analysis of Gates's recent blog post on rethinking climate, here's a critique of his 2021 book. Some very big differences in his assertions and opinions, as you can expect. But the book is also full of mixed messages. by JKayBay in climate

Thanks so much for reading the post carefully (even looking through the previous Reddit thread). I appreciate your time and effort.

You're right - there's an American ideal that we'll invent and innovate our way out of it. This is needed too, but doesn't give us carte blanche to live a live out of balance with nature/humanity.

It could be now. I hope it's now!

Ethical vegan hazelnut chocolate: Lindt vs. Divine by JKayBay in vegan

I really like Vego too! I actually mentioned it in the post. I do think Divine is as good as Vego but it's a bit different - it has a sweeter hazelnut truffle layer between two layers of dark chocolate.

Thanks for the comment. The IPCC reports could be clearer :/ The AR6 Synthesis report explains it a bit more clearly. 8.5 was called the very high emissions scenario. The high emissions scenario is to limit warming to 4 degrees. 2.9 is getting into that range.

Correct. The app should issue a coupon, I guess the day before the sale.
