Condfiguring A Non-Linear Process Control System Using Virtual Instrumentation

Abstract

It was in 1896 when S. Arrhenius first noticed the potential effect of human activities on the carbon cycle and the implications for climate change. He put forward the theory that CO₂ in the atmosphere was an important greenhouse gas and that it was a by-product of burning fossil fuels. In 1958, Charles Keeling began the observations at Mauna Loa Observatory, 3650m up a mountain in Hawaii, regarded as far enough away from any carbon dioxide source to be a reliable measuring point. Measurements of CO₂ in the atmosphere have been continuous for almost 50 years. In recent decades, CO₂ increased on average by 1.4 parts per million (ppm) a year because of the amount of fossil fuels burnt.
