change what behavior? And if we changed will it have an impact?
I saw a PBS documentary on Niagra Falls this weekend. To perserv its beauty and to generate power only about 25% of the natural water flow actually goes over the falls. How do we know that this is not a major contributor to global warming in the nortern hemishere. Water vapor is a greenhouse gas. This major manipulation of water may be doing more harm than anyone has considered.

Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many "facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
