Water Balance and Climate Change
In the context of the US National Assessment of the Potential Consequences of Climate Variability and Change (National Assessment on Climate Change) published in 2000, which was part of the US Global Change Research Program (Global Change Research Act), the National Ecology Institute of the National University of Mexico (UNAM) carried out a study on Impacts of Climate Change and Climate Variability in Mexico for the Mexican Ministry of Environment and Natural Resources. According to the study Mexico will experience less or normal summer precipitation and increased precipitation during winter. The report also details predicted impact by regions. For example, in the Lerma-Chapala basin the predicted increase in temperature coupled with a decrease in rainfall could result in severe water supply shortages, exacerbated by growth in population and industries. In northern areas and regions with large populations, especially in Central Mexico erosion and drought severity will increase with higher temperatures and rainfall variations in these arid and semi arid regions. Agricultural practices may also have to change, with a severe drought in Chihuahua in 2012, which some scientists attribute to climate change, leading to 350,000 head of cattle starving to death due to a shortage of pasture caused by a lack of rain.
Researchers have also predicted that tensions between Mexico and the US over shared water resources could increase as climate change increases water scarcity in both countries.

Famous quotes containing the words water, balance, climate and/or change:
“If there’s water in the big rivers, the small rivers will be full.”
—Chinese proverb.
“Partisanship should be kept out of the pulpit.... The blindest of partisans are preachers. All politicians expect and find more candor, fairness, and truth in politicians than in partisan preachers. They are not replied to—no chance to reply to them.... The balance wheel of free institutions is free discussion. The pulpit allows no free discussion.”
—Rutherford Birchard Hayes (1822–1893)
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
“The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
Always yield to the Hands-On Imperative!
All information should be free.
Mistrust authority—promote decentralization.
Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.”
—Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)
