If not one Senator asks him to explain the graph which shows that, through large periods of time, global warming precedes CO2 increases, then I will know that not one person in Congress cares about the science, but merely the politics of the issue.
"global warming precedes CO2 increases,"
Good point! That, and a mention of Milankovitch Cycles, and a discussion of the Maunder Minimum are my keys for checking "science".
If the senators ask serious questions they'll have to agree that the man made theory is just that......man made......and not scientific at all.
