Which of the following statements is best supported by this study? A. Most climate scientists dispute the theory of human influence on global warming. B. Global warming is most likely alarmist propaganda based on false data. C. Global warming is definitely not caused by human influence on nature. D. Most climate scientists believe that there is evidence that explains global warming.

Respuesta :

“Most climate scientists believe that there is evidence that explains global warming”  is best supported by this study.

 

The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 yearscaused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere (click the following link for a summary and graphs about the cause and effects of global warming).

 

The correct answer between all the choices given is the last choice or letter D. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
Depending on exactly how you measure the expert consensus, it’s somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding 97% consensus among publishing climate scientists.
A survey of all peer-reviewed abstracts on the subject 'global climate change' published between 1993 and 2003 shows that not a single paper rejected the consensus position that global warming is man caused (Orestes 2004). 75% of the papers agreed with the consensus position while 25% made no comment either way (focused on methods or paleo-climate analysis).
Hence,the best answer is : 
D. Most climate scientists believe that there is evidence that explains global warming.
