B) by quoting Winston Churchill to show that he also believes that climate change is a serious issue. C) by comparing the inaction of the world leaders of today to the inaction of leaders in the past. D) by showing the differences in the effects of climate change and World War II.  

The correct answers are C) by comparing the inaction of the world leaders of today to the inaction of leaders in the past.

The excerpt that develops Gore’s theme that climate change is a problem that must be addressed is “by comparing the inaction of the world leaders of today to the inaction of leaders in the past.”

Al Gore develops the urgency of attending the issues that climate change brings when in the excerpt he makes reference to the comparison made by Winston Churchill to Hitler’s threat: “They go on in strange paradox,, decided only to be undecided, resolved to be irresolute, adamant for drift, solid for fluidity, all-powerful to be impotent”.  This way, Al Gore is comparing the inaction of the world leaders of today to the inaction of leaders in the past.
