Ratings & Reviews performance provides an overview of what users think of your app. Here are the key metrics to help you identify how your app is rated by users and how successful is your review management strategy.
5.0This app provides a very simple simulation of the accumulation of carbon dioxide in Earth's atmosphere. Explore the consequences of climate change and global warming by adjusting the settings of this simulation. Use the simulation to explore what can be done to slow, stop, or even reverse global warming. The simulation assumes that global warming is caused by the increasing concentration of carbon dioxide in our atmosphere and that this increase is a direct result of the burning of fossil fuels. This app is not a complete climate simulation; that would require a supercomputer, massive amounts of data and processing time. Instead, the simulation uses the changes in atmospheric carbon dioxide over the last 20 years to project those changes into the future to 2100. If the rate of change over the last 20 years continues unchanged, then carbon dioxide will continue to accumulate in the atmosphere causing the planet to warm and sea levels to rise. Controls provide settings that allow you to simulate the result of changing the sources of energy production. Increasing the use of green energy and burning less fossil fuel will slow the warming of the planet. Energy conservation and carbon capture are also settings that can be controlled for each simulation. The default scenario for the settings is a "do nothing" scenario. If we do nothing to mitigate carbon dioxide in the atmosphere the planet will continue to warm to at least 3°C by the year 2100. To illustrate the consequences of global warming, popups will display "tipping points" and other consequences that may occur as a result of global warming. Climate change is real and global warming is happening now. However, it is a complex subject that is difficult to get your head around. Hopefully this app will encourage you to explore the subject in depth and do what you can to mitigate the consequences.
