Writing an Informative Climate Change Essay

A climate change essay would harp on the variations that develop in climate over a lengthy period of time, typically over a decade. It can occur due to natural processes that occur within the earth or can be due to external reasons mostly due to changes in the atmospheric composition or how land is used. The three main essential elements that support life on earth are water, the oxygen-rich air we breathe, and the earth’s surface temperature. The atmosphere with its composition of 78% nitrogen and 21% oxygen plays an important part in reflecting about 30% of the incoming energy from the sun. The balance reaches the earth thus helping in maintaining the surface temperature of 15 degrees centigrade approximately. The balance 0.036% carbon dioxide helps photosynthesis in plants.

Every day, the sun’s energy in the visible spectrum, ultraviolet, and infra red rays is absorbed by the seas, and land across the earth. The delicate balance of how much Earth actually needs to sustain life is maintained by absorbing the heat needed and releasing the balance in the form of infra red rays. For example, a climate change essay could include an experiment where a vessel of water is kept over fire. It starts getting hot. When we keep our hands over the lid, we can feel the head radiating into our hands. These infra red rays cannot be seen but is felt by our hand. The emitted heat is not all lost in space but partly absorbed by greenhouse gases (GHGs), that are present in small quantities in the atmosphere. A custom essay could establish that these GHGs play an important role in re-emitting the absorbed heat back to the earths’ surface. If this did not take place, the earth’s surface temperature would drop to about -18 degrees centigrade, which would make it unable to support life in any form.

The ill effects of the Industrial Revolution that began approximately 150 years ago have had its effect on the atmosphere. Essay questions need to be asked as to how man-made activities have significantly increased GHGs in the atmosphere. The gradual increase in the levels of GHGs has increased global warming and led to the phenomenon we call climate change. Scientists from the Intergovernmental Panel on Climate Change (IPCC) has established through various assignments that the earth’s surface temperature has increased by 0.74 °C over a 100-year period from 1906-2005.

Reference to a reliable essay guide over the internet would indicate that variations in the temperature have occurred earlier in Europe during the Middle Ages. The Little Ice Age brought about famine and other calamities. Even recent studies have indicated that measurements of increasing temperature varies over different layers of the lower atmosphere and when measured at different places over the globe. It has made it difficult to measure how much effect man-made activities have had to effect these changes. One thing is for certain though. Man has to pay great attention to reducing the GHGs in the atmosphere. Each country has to play its part. A climate change essay can be a good starting point to highlight the changes that need to take place.
