" When you analyze all the data, there is a warming trend according to science. But the jury is out on the degree of how much is manmade. "
- Rob Portman

Rob Portman's statement reflects a nuanced view on climate change, acknowledging that scientific data indicate an ongoing warming trend but suggesting uncertainty about the extent to which this trend can be attributed directly to human activities. He implies that while there is a clear consensus among scientists regarding global temperature increases, the specific contribution of human actions remains under debate.

By saying "the jury is out," Portman expresses that despite overwhelming evidence supporting climate change, there are still questions about how much of it is caused by humans versus natural processes. This phrase encapsulates a cautious approach to interpreting scientific data, recognizing the complexity of environmental issues and the need for further investigation before making definitive claims. It highlights a balance between accepting established science while also acknowledging areas where more research is needed.
