Carbon dioxide (CO2) concentrations (in parts per million) for the last 1,100 years, measured from air trapped in ice cores (up to 1977) and directly in Hawaii (from 1958 onwards).

A much-discussed aspect of the utilisation of fossil fuels for energy and material production in the last 20 years, anthropogenic emission of greenhouse gases as a result of their combustion can be correlated to objective measurements of climate change. Though alternative explanations to the greenhouse effect are offered by sceptics for the increase of global temperature, it is a fact that CO2 concentration in the atmosphere has increased radically as from the advent of the Industrial Revolution (see Figure), which hailed a rocketing increase in coal extraction and burning.
