The Rocket Mass Heater takes this useful, clean-burning heat, adds a self-feeding wood box, and channels the exhaust through a masonry block to store touchable warmth for hours or days.(Masonry heat storage is also seen in Roman hypocausts, Chinese 'kang' stoves, European masonry heaters, and ancient masonry dwellings and hearths).Natural processes absorb the equivalent of all natural emissions plus about 57% of man-made emissions, leaving an additional 16 billion metric tons of CO2 in the atmosphere each year. † In permafrost regions, perennial snow accumulations trap air bubbles that leave records of past airborne CO2 concentrations,   and because regional CO2 concentrations vary by less than 10 parts per million over the Earth, these local records are globally representative.  * Instruments located on satellites can measure certain properties of oxygen that vary with temperature.Data from these instruments is used to calculate the average temperatures of different layers of the Earth’s atmosphere.  * The lowermost layer of the atmosphere, which is called the “lower troposphere,” ranges from ground level to about five miles (8 km) high.  According to satellite data correlated and adjusted by the National Space Science and Technology Center at the University of Alabama Huntsville, the average temperature of the lower troposphere increased by 0.60ºF (0.33ºC) between the 1980s and 2000s, mostly from 1997 to 2010: * Sources of uncertainty in satellite-derived temperatures involve variations in satellite orbits, variations in measuring instruments, and variations in the calculations used to translate raw data into temperatures.  * According to temperature measurements taken near the Earth’s surface that are correlated and adjusted by NASA’s Goddard Institute for Space Studies, the Earth’s average temperature warmed by 1.5ºF (0.8ºC) between the 1880s and 2000s, mostly during 1907–19–2014: * According to temperature measurements taken near the Earth’s surface that are correlated and adjusted by the Climatic Research Unit of the University of East Anglia in the U.(KJV) And Samuel said, Hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord?Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
Variations on the same concepts include Fox-stoves or Badger-stoves, cooking Rocket Stoves, Dakota firepits, traditional furnaces, kilns, modern incinerators, smokestacks, bell-stoves, and millions of humble tea-stoves and household hearths developed by resourceful people all around the world.
Common denominator besides the vertical "heat riser" may include a passion for channeling that heat in more efficient ways (for example through cooking directly over the chimney, or using thermal mass to store long-term heat, or adapted cooking facilities such as well-insulated ovens and pot sleeves), and creative use of basic materials such as scrap metal, adobe, and other local resources.
