Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. They measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America. They attributed this upward trend to rising CO2 levels from fossil fuel emissions.
