I'll assume the "obvious solution" is a cold-turkey (or over the next 10 years) complete or almost complete cessation of all CO2 emmissions. Where will the fertilizer come from? What happens to the parts supply chain and fuel sources of agricultural machines? How will we make concrete and steel in the quantities we need? How will we transport food across continents? In summary: How can we do that without a death toll of tens of millions? I mean we are slowly working on it, solar+storage is now just the most cost-efficient source of electricity. But anyone that thinks it is simple or obvious either doesn't inhabit the real world, or is a murderous psychopath.
