Question

The United States leads the world in energy consumption. Which effect of energy use is the source of the greatest disagreement among American politicians? engine mileage climate change gasoline prices oil drilling

Answer 1

This is a bit tricky, but in general, it is climate change that is the source of the greatest disagreement among American politicians, because some people still think it doesn't exist.

Answer 2

The right answer from the options above is Climate change.

This is the variation in the state of the climate system, which lasts for sufficiently long periods of time until a new Balance. It can affect meteorological values as much as their variability and extremes.  Current climate change is very expected to be completely anthropogenic and is mostly related to the rise of the greenhouse effect due to industrial emissions from the burning of fossil fuels. The probable contributions of natural forcing and inside variability to the change in global temperature since 1951 are negligible.
