Your friend Jessica says she doesn’t believe in climate change, since the Earth has always gone through warming cycles. She says all the impacts we are experiencing now are a result of those cycles, and they will eventually slow down and stop as the Earth comes out of the cycle. “Plus,” she says, “it’s been really cold this winter, so there can’t be a changing climate.” Reference: Ref 10-3 Climate models show that when we consider both anthropogenic and natural forcers together, the result is:

If current rates of use and extraction do not change, known natural gas reserves are expected to last _____ years.

What is a major drawback of clean coal technologies?

A shift of only a few degrees Fahrenheit in the average global temperature will likely result in more frequent and extreme heat waves. Which example BEST describes this phenomenon?

If current rates of use and extraction do not change, known natural gas reserves are expected to last _____ years.

Which reason is NOT one why our energy supplies may become unreliable or unaffordable?

Without greenhouse gases, the average temperature on Earth would be:

_____ is/are anything that alters the balance of incoming solar radiation relative to the amount of heat that escapes out into space.
