Clearly, they are ignoring the very definition of any scientific theory. Wikipedia says it best:
"A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation."Simply, the theory of CO2 caused global warming is neither well-substantiated nor repeatedly confirmable. The proof comes from the simple fact that there has been no global warming for nearly 18 years. This despite the fact that global atmospheric CO2 levels have risen 61% in the last 24 years, and continue to rise at a rate of about 2% a year. So, in essence, the connection between CO2 and global warming is broken and climate scientists have no explanation for this. Well, just maybe, they have no explanation because their theory is seriously flawed. Flawed because it appears that factors other than CO2 are truly influencing temperature.
Rubio also stated that our go-it alone laws in controlling climate change aren't going to control world atmospheric CO2 levels and are only going to destroy our own economy. Again, he's right. As noted before, CO2 levels have risen 61% in 24 years. At the same time, the U.S. has reduced its carbon emissions to levels that haven't been seen since 1994. This despite the fact that our population has increased by almost 20% in those same twenty years. In terms of reducing carbon emissions, the U.S. is the world leader. Yet, CO2 levels continue to rise because countries such as China and India are more than offsetting any reductions in carbon dioxide by the U.S. or any other industrialized nations.
