… Mercury—and That's Bad News.

"As Arctic permafrost thaws, it unleashes a vicious cycle—the unfrozen soil releases its carbon reserves that intensify climate change, in turn accelerating the thaw. Now researchers have reported another disturbing discovery: The permafrost holds a much greater cache of mercury than thought—and as the ground warms, it could potentially release that toxic metal on the world.

In the new study, published this week in Geophysical Research Letters, an international team of scientists drilled 13 permafrost soil cores at various locations in Alaska. Back at their lab they analyzed the frozen cores to measure factors such as moisture, organic carbon and mercury content. The 50- to 100-centimeter cores spanned a time between 22,000 and 2,400 years ago, meaning the vast majority of mercury they hold came from nonhuman sources. The researchers used their measurements to extrapolate an estimate of how much mercury is stored in the entire Northern Hemisphere's permafrost…"

"meaning the vast majority of mercury they hold came from nonhuman sources."

Has anyone told Giorgio A. Tsoukalos yet?

He says it's possible. :)

Dan

Has anyone ever noticed that you never see Dan and Giorgio in the same place at the same time? Hmmm, makes me wonder… Is it even possible?

(Dramatic pause)

Yes it is …

Dan

Or, is it?

The real question is: Which one is actually the evil twin?

Perhaps the making of a new TMP Poll!

Dave

I'm not telling. :)
