A growing world population, global warming, growing fossil fuel use and greenhouse gas emissions and ongoing, growing disparities in the distribution of wealth and income and business-as-usual political economy – all threaten national, regional and international efforts to assure all members of society fair access to sustainable water resources. ...

PREHISTORIC SHORELINES Researchers explored ancient rock formations on South Africa’s coast. They are looking for critical clues from records of past climate change to help predict sea level rise in a warming world.

BREDASDORP, South Africa — A scruffy crew of scientists barreled down a dirt road, their two-car caravan kicking up dust. After searching all day for ancient beaches miles inland from the modern shoreline, they were about to give up.

Suddenly, the lead car screeched to a halt. Paul J. Hearty, a geologist from North Carolina, leapt out and seized a white object on the side of the road: a fossilized seashell. He beamed. In minutes, the team had collected dozens more. ... Read more about How High Could the Tide Go?

Feeding the 9 Billion: The tragedy of waste

By 2075, the United Nations’ mid-range projection for global population growth predicts that human numbers will peak at about 9.5 billion people. This means that there could be an extra three billion mouths to feed by the end of the century, a period in which substantial changes are anticipated in the wealth, calorific intake and dietary preferences of people in developing countries across the world. ...

By the middle of the century, the scores of billions it cost to compensate the greater New York City area for being unprepared for superstorm Sandy may seem like a bargain. Without major adaptation measures to increase the level of storm protection beyond a 1-in-100-year event, the value of the city’s buildings, transportation, and utilities utility infrastructures currently at risk from storm surges and flooding — an estimated $320 billion — will be worth $2 trillion by 2070, according to continuing studies by the Organization for Economic Cooperation and Development (OECD). ...
