The difference is basically a spectrum from pure engineering to pure science. At first, pure science is really volatile, where as pure engineering can be a simple matter of talent and funding. Execution risk is much lower on the engineering side. There are many climate related issues that are bound by engineering.

Not quite accurate, some climate cos getting funded at Seed and preseed by Fifty Years and Lower Carbon. Trick is small number of great teams here, who also see a distinctive advantage to going through YC. YC can’t overcome that without significant effort.

Well said. I imagine a group like Lower Carbon Capital (https://lowercarboncapital.com/) would be better suited to provide expertise.
