===Presence of CO₂===

One of the primary concerns of Global Warming research is the increased presence of carbon dioxide in the atmosphere. Original claims stated that the increase in carbon dioxide - which is a greenhouse gas - were caused primarily through the burning of [[fossil fuels]], and that such increases were the foremost cause of global temperatures rising. Historically, Global temperature changes precede changes in carbon dioxide in the atmosphere.<ref> [http://www.skepticalscience.com/co2-lags-temperature.htm]</ref>
