You're absolutely right in that:
"It is hard to imagine two environs more different than
the Amazon rainforest and the Canadian Arctic.
Yet here too researchers have found high emissions of
greenhouse gases from reservoirs."

Thanks for the link Randal,
However, I find that the accompanying diagram, "Hydropower Polluters," is
not very useful -- one could even say its misleading.
The map only provides surface areas of dammed waters, in millions of
It says *nothing* about the relative importance of each hectare, in terms of
GHG production, at various latitudes.
