Greenhouse gases - CO2, methane, and nitrous oxide - create a heat-trapping effect in the atmosphere. Instead of biodegrading, they bio-accumulate by forming tight bonds. These resulting compound molecules do not break down in the atmosphere. Instead, they build up in the air, The accumulation of carbon dioxide in the air stems from several activities, including deforestation and burning of fossil fuels. In addition to creating warmer temperatures, excess carbon dioxide lets stronger sun rays penetrate the atmosphere, which also causes rising temperatures.
Temperatures are not rising as significantly as predicted, there are many factors that are not included in the models such as the positioning of heat sinks near instruments. The problem is humans think that we are in control, that we can control our environment. If we were serious we would limit population and stop destruction of forests to grow crops such as soya, palm and corn. Forests are needed to sequestrate carbon. The oceans playa huge role in climate and sequestrating carbon
