Sunday assorted links
1. Carbon emissions embedded in trade.
2. How zoos convince animals to get vaccinated.
3. How will radical on-line ideology evolve? It is important whether or not this is true.
4. Some of them are frauds. And more from the NYT, is the debate really this insipid? I think so.
5. How fast do people improve their chess? And an HN thread on same.
6. In some ways, this is a better article than it will seem to you: “Why we should talk about what Kyrsten Sinema is wearing” (NYT)
