We are indeed in one of the warmer periods of Earth's ever changing weather.
The climate of Earth is a complex and chaotic system influenced by many variables, which include changes in solar radiation, cloud cover, ocean currents, volcanic activity, planetary orbits and El Nino events. Changes in the climate occur slowly but continuously. For millions of years the planet has been either warming or cooling. Carbon dioxide is a trace gas with a concentration of 0.04 per cent of the atmosphere. It has the ability to absorb a narrow band of energy and prevent that particular wavelength of heat from escaping to space. It can, therefore, be called a greenhouse gas. However, its effect on the climate is so small as to be insignificant when compared with water vapour and, more importantly, the sun.
