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