Which gases are causing the most change? The main greenhouse gas responsible for recent climate change is carbon dioxide (CO2). This has been released in huge quantities by our modern way of life. Levels have also increased due to the destruction of rainforests, which play an important role in absorbing CO2. Human activities are increasing other greenhouse gases too, such as methane and nitrous oxide. Methane is produced by bacteria that live in places like landfill sites, peat bogs and in the guts of animals like cows and sheep. Nitrous oxide is increased by the use of nitrogen fertiliser in agriculture. Both these gases have a powerful greenhouse effect and also contribute to climate change. However, they have not been released in such large quantities as CO2 and methane does not last for as long in the atmosphere. So, while they make a significant contribution to climate change, it is man-made CO2 which has by far the greatest influence.
