Any type of gas that becomes stuck in the atmosphere can be considered a greenhouse gas that contributes to the greenhouse effect. Carbon dioxide gases are the most common of these, commonly referred to as carbon emissions. Methane and nitrous oxide are some other greenhouse gases. Typically, emissions are the byproduct of burning fossil fuels and conducting various agricultural activities. Every time we burn fossil fuels, it releases carbon into the atmosphere. This carbon creates a little invisible ring around the atmosphere, trapping the heat from the sun and causing the Earth’s temperature to rise. It almost acts as an unwanted sunbed turned on high.
