Organic greenhouse gases are identified by many experts as contributors to the warming of the planet, as these gases build up in the atmosphere, trapping heat and causing temperature increases. Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and fluorinated gases, absorb and absorb energy from the sun, creating an overall warming effect. This phenomenon is known as the “Greenhouse Effect”. Greenhouse gases are a naturally occurring part of the atmosphere, but the increase of human-generated emissions of​ greenhouse gases has caused a rapid acceleration of the greenhouse effect, leading to a rapid rise in global temperatures and the phenomenon known as global warming.
The CO2 emissions from automobiles and industrial activity account for much of the additional emissions and are considered by many as the largest contributors to the “anthropogenic” portion of the greenhouse gas effect. In addition, other activities such as the burning of fossil fuels, deforestation and agricultural practices have all been linked to an increase in greenhouse gas (GHG) emissions. The release of gases like CH4, N2O and Fluorinated gases, from industrial and agricultural procedures, also adds to the build-up of GHGs in the atmosphere.
The warming resulting from GHGs is intensifying global climate change, causing extreme changes in local weather, resulting in higher rates of drought, flooding and other extreme weather conditions. The United Nations Intergovernmental Panel on Climate Change (IPCC) has estimated that the average global surface temperature has increased by 1.1 degrees Celsius since the 19th century. Over the last three decades, the overall rate of warming has been amplified, with average global temperatures rising by approximately 0.2°C per decade according to the US National Oceanic and Atmospheric Administration (NOAA).
These dramatic increases in temperature have caused significant changes in ice-covered regions. The IPCC has reported that the Arctic is warming at almost twice the rate of the rest of the planet, causing an overall shrinkage of the Arctic sea ice cover, as well as glacier and ice sheet loss in Greenland and Antarctica. Warmer oceans are also impacting sea life, resulting in coral bleaching, as well as increases in ocean acidification.
In addition to the effects already discussed, global warming will also cause more frequent and intense spells of intense weather related phenomena, such as extreme heat waves, heavy rains and floods, hurricanes, and violent storms. This, in combination with the higher temperatures, will result in an overall increase in the frequency and intensity of weather related disasters, as well as in drought and famine.
With these impacts in mind, it is clear that reducing emissions of GHGs is paramount in order to prevent further global warming, as well as reduce the intensity of its effects. Governments, industries, and consumers alike must take proactive action to reduce emissions, by investing in renewable energy sources, implementing more stringent emission standards, and engaging in sustainable practices. Additionally, citizens must be educated on energy efficiency and sustainable living practices, in order to help reduce the amount of GHGs being produced.
In conclusion, greenhouse gases are undeniably a key factor in global warming, and drastic action must be taken in order to reduce the amount of GHGs being released into the atmosphere. It is our responsibility to take care of our planet and ensure its longevity for future generations. Taking proactive steps now will ensure a more sustainable future for all.
