Let’s count the reasons why Marco Rubio should be eliminated from consideration not only as a presidential candidate but as a US Senator. He’s in way over his head. Having an education and professional certifications are essential elements for being qualified to become an elected official. But, there are many additional considerations that include relevant skill, knowledge, and experience as well as sound judgment. Rubio is a strike out at many of these things. Having him in office longer does not address his deficiencies, and apparently it makes him worse off.
His latest foray into the land of ignorance is his personal belief that climate change is not caused by humans. That is so outrageously stupid that he must be removed from all consideration. He has failed at all that he attempted to accomplish including immigration reform. Acts of ignorance are just like acts of lying. You cannot trust a liar, nor can you trust a person of ignorance and bad judgment.
“Potential 2016 presidential candidate Sen. Marco Rubio isn't willing to blame human activity for the dramatic changes in weather in the world and doesn't think we can do much about it.
“I do not believe that human activity is causing these dramatic changes to our climate the way these scientists are portraying it and I do not believe that the laws they propose we pass will do anything about it, except it will destroy our economy,” Rubio, R-Fla., told ABC on Sunday.
Rubio made his comments as the White House has been trying to move climate change back to the forefront. Last week, the Obama administration released theNational Climate Assessment, the result of four years of research by hundreds of scientists and experts.”
"Scientists have pieced together a picture of Earth’s climate, dating back hundreds of thousands of years, by analyzing a number of indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, and by studying changes in Earth’s orbit around the sun. 
The historical record shows that the climate system varies naturally over a wide range of time scales. In general, climate changes prior to the Industrial Revolution in the 1700s can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas (GHG) concentrations. 
Recent climate changes, however, cannot be explained by natural causes alone. Research indicates that natural causes are very unlikely to explain most observed warming, especially warming since the mid-20th century. Rather, human activities can very likely explain most of that warming.
