So what do you say to this denialists?

As I posted in the last piece, there is a cavalcade of climate conspiracy theorists out there. "Climate change is a hoax!" they cry.

So I just wonder what they think of this story from Penn State Live: 'Supra-glacial lakes' are the focus of a new Penn State study. They write the following:
University Park, Pa. -- Rising temperatures on the Greenland ice sheet cause the creation of large surface lakes called supra-glacial lakes. Now a Penn State geographer will investigate why these lakes form and their implications...

"Learning where lakes are, how they form, and how that changes through the melt season can help us really understand a lot about important processes that control how the Greenland ice sheet responds to warming," Lampkin said.

Supra-glacial lakes form when melting water collects in pools in the lower levels of the ice sheet in melt or ablation zones. These lakes drain rapidly through cracks in the ice channeling water to beneath the ice sheet, affecting how ice sheets move and how pieces calve off into the ocean.
I wonder what tomorrow's Young Americans for Freedom and 9/12 Project protesters about so-called "Climategate" think of this direct empirical evidence positively correlated with rising human-produced atmospheric greenhouse gases. Is this a joke to them? To my mind, that is willful ignorance. When will there be enough evidence for them?
