Pick one of the erroneous statements below and correct them, briefly explaining why they are incorrect based on scientific evidence and scholarly sources or by going back to definitions and using them clearly.

#1. The greenhouse effect and global warming are the exact same thing.

#2. Global warming means that the weather will be warmer and generally “nicer”. The cooler than usual winters and milder and rainy summers show that global warming is not happening.

#3. Stratospheric ozone depletion causes global warming.

#4. Carbon dioxide (CO2) causes stratospheric ozone depletion.  (This is a good time to review CHEM 297 to explain why this statement is incorrect.)

#5. Ozone pollution is not a serious air pollution problem. In fact, it can help solve the ozone layer problem.

#6. Electric cars are not better than gasoline-powered cars because electricity is mostly produced from coal, so total carbon emissions are about the same.

#7. Renewable energy is too expensive. It would hurt the economy to make a switch from fossil fuels to renewable energy.

#8. Biofuels are an environmentally friendly alternative to gasoline, because they are renewable and a carbon-free source of energy.

Please select a statement not previously covered by one of your classmates or add on to what your classmates have discussed with additional insights.
