5.2.1 Globally, the potential for food production could increase if
local average temperatures rise by 1 to 3 °C, but would decrease if temperatures rise further.
By the end of this century, according to the new research, some «megapolitan» regions of the U.S. could
see local average temperatures rise by as much as 3 degrees Celsius, in addition to whatever global warming may do.
By comparing different countries, compute the «sensitivities» dX / dT and dX / dC where T is
the local average temperature and C the fossil fuel consumption.
