Question

Read the excerpt from "Climate Change: An Overview.”

Today, ninety-seven percent of climate experts agree that humans are causing climate change. No scientific body of international or national standing dissents from this view. (A few maintain a non-committal position.) That is not to say that the research is universally accepted. As long as scientists have been positing that human emissions of greenhouse gases are heating up the planet, others have denied their arguments.

The statistic in this excerpt supports the idea that

carbon emissions and climate change are not related.
scientists are divided about the impact of carbon emissions.
scientists and the general public disagree about carbon emissions.
carbon emissions are directly related to climate change.

Answer 1

carbon emissions are directly related to climate change.

The 97% agreement among climate experts indicates a strong consensus that human (greenhouse gas/carbon) emissions are causing climate change.
