What exactly is “global warming” anyway? That’s really four questions:

1. Is the globe warming? *******Probably********(Lie). Global temperatures have risen**********(Lie). Climate changes. Always has. Always will.

2. Is the warming caused by man? Maybe. There’s decent evidence that at least some of it is*********(Lie).

"Probably" is a lie? And by the way, global temperatures HAVE risen over the period in which records have been kept.

"Maybe. There's decent evidence that at least some of it is" qualifies as an expression of opinion. Sort of like YOUR opinion that "man could not possibly" cause it.

The globe is warming since 1979 unless you don't believe satellites function as they were designed: http://www.drroyspencer.com/latest-global-temperatures/ The source of that warming can be CO2 in theory. The rise in CO2 is manmade with nearly no doubt based on estimates of fossil fuel use. There is definitely natural variation and that includes some of the warming measured by the satellite.

To say some scientific claim is a "lie" means there is "proof" which automatically means it is not science, but dogma.
