Question

In the 2006 documentary An Inconvenient Truth, former Vice President Al Gore strives to inform the public

Answer 1

Answer:

there is some disagreement about the existence and impact of global warming

Explanation:

The passage above shows that there is, somehow, a disagreement when it comes to the existence and impact of global warming. Although President Gore tries to tell the people of the dangers of global warming, some says that global warming is not true. Other people say that it has an effect  or impact on the animals. The ideas stemming from this issue are opposing each other. This means that not everyone has the same opinion regarding the existence and impact of global warming in the world; thus, the disagreement.
