The real challenge is figuring out whether a particular storm or flood was due to climate change or natural variables, said Chris Field, founding director of the Carnegie Institution's Department of Global Ecology.
Clues to how one currency will move against another are found in a slew of variables, including interest rates, budget deficits, surpluses and the political climate.
This is why one of the most vital projects of this new century, defined by climate change and growing energy and resource scarcity, is to figure out a way to build these variables back into our economic system.
