solved There is overall scientific consensus on climate change. This consensus
There is overall scientific consensus on climate change. This consensus is in two main areas. One is that the climate has been very stable for centuries but it is starting to change in a big way. The other is that human activity has caused these changes (mostly through the release of greenhouse gases, especially CO2 into the atmosphere.) Â Â Land use changes also play an important role. Â Why do you think that the populace is unwilling to accept the results? Be specific.
Before humans evolved, the average amount of CO2 in the atmosphere was between 180-280 ppm. Recent reports have stated that by 2050 we should expect that CO2 levels will be >550 ppm along with current readings that put it over 400 ppm for the first time in over a million years. Discuss the effects of this amount of CO2 on the food chain. (There is information in the U of A podcasts that will help with this.)
One of the big problems we’ve learned about in climate science is the idea of “feedback”. Some effects of larger CO2 concentrations actually make it more likely that CO2 will increase (through “positive feedback”). Write about one of the positive feedback mechanisms that are discussed in the climate change podcasts. Be specific.
In his book “The Madhouse Effect”, Michael Mann discusses the stages of climate change denial. Find a recent news article that illustrates one of these phases. Discuss the details of the news item and how it illustrates denial. Be specific.
Look at the Carbon Dioxide data from the EPA. Â Would these numbers have affected the choices that you would have made in the Energy I module? Â Do they makes some sources much worse than others?
In some ways the COVID-19 crisis is is similar to and different from the global crisis over climate change. Â What are some of the similarities and some of the differences between the two situations?
