(Phys.org) —Recent studies have shown that the Earth's tropical belt—demarcated, roughly, by the Tropics of Cancer and Capricorn—has progressively expanded since at least the late 1970s. Several explanations for this widening have been proposed, such as radiative forcing due to greenhouse gas increase and stratospheric ozone depletion.
