Dear Skeptic: What issues should be debated?

Dear Society Driven Global Warming Skeptic: Can you outline the issues that need to be debated?

Of late, skeptics such as Dr. Spencer, Anthony Watts, Mr. McIntyre, etc... et al.

Have been displaying great indignation that genuine practicing scientists and other climate experts refuse to "debate" with them.

In traveling around the blogosphere I read comments from many sincere folks who mirror Mr. Watts' vocal and melodramatic indignation over at WattsUpWithThat.com.

And me, 

I wonder, 

in light of the past decades of the experts debating,

and challenging each other - 

and in light of all we have observed,

and all we have learned regarding the physics:

What is it that the Dr. Spencers and Anthony Watts of the world want to debate anyways?

Dear Skeptic,

can you outline the issues regarding our current society driven global warming knowledge that needs to be debated?
