That would mean more time to address whatever problems man-made climate change may cause
Alex Parfenov/DreamstimeProbably the most vexing problem in climate change science is determining how hot the planet would become if the amount of carbon dioxide in the atmosphere doubles from it pre-industrial level of 280 parts per million. Known as equilibrium climate sensitivity (ECS), the Intergovernment Panel on Climate Change’s Fifth Assessment Report put the likely range of ECS as being between 1.5 and 4.5 degrees Celsius.
The current level of carbon dioxide in the atmosphere is around 403 parts per million. Carbon dioxide in the atmosphere is now increasing annually at about 3 parts per million. If that rate of increase keeps up, the amount of carbon dioxide in the atmosphere will double by the end of the century.
