Introduction to
climate change
7. Atmospheric CO2 has increased from a
pre-industrial concentration of about 280 ppmv to about 367 ppmv at
present (ppmv= parts per million by volume). CO2 concentration data
from before 1958 are from ice core measurements taken in Antarctica
and from 1958 onwards are from the Mauna Loa measurement site. The
smooth curve is based on a hundred year running mean. It is evident
that the rapid increase in CO2 concentrations has been occurring since
the onset of industrialization. The increase has closely followed the
increase in CO2 emissions from fossil fuels.
