The more we learn about this one, the better. No one knows the likelihood of, say, Greece, to pull an example out of the air, pulling out of the Eurozone and reverting to the drachma. I'd guess not, but the potential is obviously real and growing.
In the midst of all of the economic and financial uncertainty, it's easy to forget the looming issue of climate change. Yet if we do not act and find a solution, issues such as the size of Greece's debt may unfortunately be somewhat academic.
