From EARTH Magazine -- "Virtual water" was coined in 1993 to help explain why long-predicted water wars driven by water and food security had not occurred among the arid nations of the Middle East and North Africa. The virtual water notion refers basically to the total amount of freshwater, either from rainfall or irrigation, used in the production of food commodities, including crops and fodder-fed livestock, or other goods and services - agricultural, industrial or otherwise.
In the last century the coastline of Louisiana’s Lower Mississippi Delta has experienced an enormous loss of land.

From EARTH Magazine -- The last several decades have seen Arctic sea-ice minimums drop by more than half in area and more than three-quarters in volume.

From NSF -- Just in time for World Oceans Day on June 8, cometh El Niño. But is El Niño really on the horizon? How certain are we of its arrival? And how will we know it's here? What effect will it have on the weather, on coastal species and on what's on our dinner tables?
