I'm sure the US could feed all those people but can the planet survive doubling US greenhouse gas emissions?

Feeding is going to be a lot harder as more land is eroded.

Though the US could cut emissions in the neighborhood of entire developed countries in Europe right now if they just stopped military spending.

The planet and nature would survive just fine - it’s just that people wouldn’t.
