Solved cryptogram

Double the temperature of a glowing object and it radiates sixteen times as much energy.

What it means

The power radiated by a hot surface climbs as the fourth power of its absolute temperature, so small increases in heat produce large increases in output. This is why a filament that is only modestly hotter is dramatically brighter, why a star's surface temperature dominates its luminosity, and why the Earth's climate is so sensitive to changes in how much heat it can shed to space.

The claim comes from NIST.
