Water is life, some would state. Water resources determined success of some of the world’s greatest cities: Baghdad, London, Rome, Singapore. Environmental consequences of climate change can be observed in water resources: floods devastate; drought strangles. Earth, the water planet, may be running out of water. Will “Water Act!” convened in Paris by the Fulbright Association produce consensus and action regarding world water?
As water becomes more scarce on earth, the element begins to be discovered in space. Earth’s solar system contains 23 oceans. Europa, Jupiter’s moon, may house a sub-surface ocean “vigorously convecting” with Hadley cells and ice plumes 124 miles high. Water movement on Europa may mean life; circulating from equator to poles, as evidenced by plumes, moving water may create the fertile environment for life. Findings of Krista Soderlund of University of Texas Institute for Geophysics and colleagues may indicate it is more likely to find life in Europa’s ocean than its land surface: water is a life-giving medium. Planetary Resources is aiming to harvest minerals, and water, from asteroids. Finding water in space may bode well for building a better future; perhaps Gerard K. O’Neill’s vision will be realized, guided in part by the United Nations Outer Space Treaty and Unispace.
Meanwhile, on earth, the world seeks to protect and preserve what water we still have. California continues to address change; citizens successfully met Governor Edmund G. Brown’s challenge to reduce water usage 25%. Differentiating water utilization for people, agriculture, building, industry, and technology might be the way of the future, as suggested by Régine Engström, Executive Director of Eau de Paris, proposing “non-potable water systems may help build tomorrow’s sustainable city.” The 2015 United Nations Climate Change Conference convening in France will seek goals of ambition, fairness, post-2020 financing, and pre-2020 actions regarding climate change and environment. What should COP21 recommend regarding water?
