Carbon Dioxide (CO2)
CO2 is the basis of life on Earth. While CO2 courses through the planetary fabric of earth, water, plants and the atmosphere, it also runs through our lives as the defining anthropogenic imprint on the world humanity has created. Small amounts of CO2 added to the atmosphere since the industrial revolution have enhanced surface warming and the dynamics of the Earth system. Small changes in the climate system can wield a host of disruptions to the lifeways of society involving food and water availability, energy production and our economic systems. The CO2 profile as a greenhouse gas (GHG) is shown below with other GHG’s and their warming potential, atmospheric lifetime, molecular weight and radiative forcing. Note that a full GHG budget would include measurements for all of the gases listed, however, rarely are such full budgets measured in practice. PαC intends to increase the number of GHG’s directly measured by the System of Systems network resulting in a multi-gas GHG emissions measurement and reduction approach.
