Average human height at age 2 is about 868mm, the growth rate by age 2 usually continues at a fairly steady rate of about 2½ inches (6 centimeters).
The IPCC intervenes uses great algorithms to extrapolate the data and concludes at age 60 humans will be 4348 mm tall - clearly unsustainable and impose a medically induced height restriction to ensure we don't outgrow the limits of our environment.
Oh sorry about that we selectively omitted humans stop growing at adolescence, but that's just a triviality, let Joh Bjelke worry about that.
