Read the excerpts about climate change.

Article 1, found on the website of the Natural Resources Defense Council, a certified charitable organization, supports global warming.

Global warming doesn't create hurricanes, but it does make them stronger and more dangerous. Because the ocean is getting warmer, tropical storms can pick up more energy and become more powerful. So global warming could turn, say, a category 3 storm into a much more dangerous category 4 storm. In fact, scientists have found that the destructive potential of hurricanes has greatly increased along with ocean temperature over the past 35 years.

Article 2 was written by Michael Fumento, writer for the New York Post editorial blog, who does not support global warming.

Back in 2005 I and others reviewed the entire hurricane record, which goes back over a century, and found no increase of any kind. Yes, we sometimes get bad storms—but no frequently now than in the past. The advocates simply ignored that evidence.

Fact is, the earth was cooling and warming long before greenhouse gases could have been a factor. The [global warming supporters] have been proved wrong time and time again.



Which best justifies the accuracy of the claim?

Although Article 1 mentions evidence discovered by scientists, more research is needed about the data source to determine if the claim is scientific.

Article 1 is a scientific claim because it says that global warming doesn’t create hurricanes.

Although Article 2 mentions the study of a hurricane record, it is a scientific claim because the author himself reviewed it and is therefore an expert.

Article 2 uses a scientific claim because the author says the Earth is in a cooling cycle.
