Increased levels of carbon dioxide (CO2) in the atmosphere have resulted in the warming of the troposphere and cooling of the stratosphere which is caused by two mechanisms. One mechanism involves the conversion of translational energy of motion or translational kinetic energy (KE) into Infrared radiation (IR) and the other method involves the absorption of IR energy by CO2 in the troposphere such that it is no longer available to the stratosphere. The former dominates and will be discussed first. For simplicity, both methods will be explained by considering a model of a fictitious planet with an atmosphere consisting of CO2 and an inert gas such as nitrogen (N2) at pressures equivalent to those on earth. This atmosphere will have a troposphere and a stratosphere with the tropopause at 10 km. The initial concentration of CO2 will be 100 parts per million (ppm) and will be increased to 1000 ppm. These parameters were chosen in order to generate graphs which enable the reader to easily understand the mechanisms discussed herein. Furthermore, in keeping with the concept of simplicity, the heating of the earth and atmosphere due to solar insolation will not be discussed. A short digression into the nature of radiation and its interaction with CO2 in the gaseous state follows.
In a digital world communication is of importance. Often scientific topics are hard to comprehend due to terminology. My goal is to spread science in an easy understanding way for everyone. In this way, we can as a community tackle #fakenews and teach the wide public. STEM education is of utmost importance in a rapid changing technological world. Our generation is obligated with the task to tackle issues like climate change.
On my website, I'll provide blogs about scientific topic's and write about my experiences with pseudo-science spreaders on social media.
All content is reviewed within my inner circle of contacts with experience in the field, however there are no spelling and language checks, I apologize for this inconvenience.
I hope that you enjoy my writings and learn from them!
Before we start, take a look at the ocean currents. This is going to be playing a very important role in sea level rise. As cold water gets heated, and hot water gets cooled due to these currents. What happens with the water in our oceans is called thermal expansion. Get ready for some facts on Seal level rise!
Late May 2021 I got diagnosed with skin cancer. As a science enthousiast I found myself with the question. "Can it be related to climate change?" The answer is Yes!
Anonymous twitter troll @DawnTJ90 still fails to apologize toward Solar Physicist Dr. Theodosios Chatzistergos for intentionally quote mining.
