Visualising Pollution with Schlieren Optics

In this experiment we have altered the colours of the schlieren results to relate to the colours used in pollution maps. The colours progress from blue to red to indicate the increase of pollutants in the atmosphere over time. Blue suggests a low amount of greenhouse gases, thus a lower global temperature and Red implies the increases of both greenhouse gases and temperature. The proliferation of greenhouse gases  can also be denoted through the way the visuals get more erratic and chaotic towards the end. Also the circumference of the circle blurs as it turns red; indicating the deterioration of the ozone layer.
