Hypocausts were heating systems that distributed the heat from an underground fire throughout a space beneath the floor. The heat was absorbed by the floor and then radiated into the room above. The effect on thermal comfort must have been similar to that of a modern-day hot water or electricity-based radiant floor heating system.

The impacts of non-CO2 aircraft emissions at high altitudes came to prominence back in 1999 following publication of a special report by the International Panel on Climate Change (IPCC) on aviation. This estimated the total historic impact of aviation on the climate to have been two to four times higher than for CO2 emissions alone.
