Adaptation is also a viable solution. It's not out of the realm of plausibility we will be able to convert energy directly into food stocks via bioreactors. G

Adaptation is also a viable solution. It's not out of the realm of plausibility we will be able to convert energy directly into food stocks via bioreactors. Global weather/climate induced crop failure is literally the only doomsday scenario for mankind w.r.t. climate change. If we can figure out how to synthesize carbohydrates, lipids and proteins with low energy inputs, climate change won't be such a big deal.
