      If you had to gauge a random stranger's intelligence + creativity with a single question, what would it be?

      Fun Q! Some ideas: + Should Canada join the EU? + What's an unusual (or fun) approach to climate change? + How would the world change if money - the actual tokens - could have negative value, e.g., a bill with a value of (-1) dollars?

      We all breath out 1kg of CO2 each day or ~3billion tonnes collectively each year. Does this contribute to global warming? If so, what should we do about it?

      AFAIK, the first-order answer is it doesn't contribute. That Carbon has its origins in plant matter, which we grow. So what's going on is: CO2 in the air => plant matter => (animals) => humans => CO2 in the air. There are complications, but that's the basic story.

      It may, in fact, have a _negative_ effect, since that cycle is very inefficient, and requires far more CO2 in than comes out. I.e., human crops are (probably) a pretty good net carbon sink.

      No. Agriculture makes up ~15% of co2e emissions via methane/n2o. Big leakages in non-co2 food production.. likely the opposite

      I was referring to CO2 emissions (per my last sentence), not overall forcing.
