CALIFORNIA SHOULD BE PREPARING FOR A 100 - 200 YEAR MEGADROUGHT

According to core samples taken by scientists, California is in the driest period since the 1500's. The scientist being interviewed said California should be prepared for a ONE HUNDRED YEAR DROUGHT. The evidence is there, and like all 'natural' cycles, the trees do not lie. Regular mega droughts are part of what happens on just about every continent and in every state. California is no exception to this rule. For some before and after pictures that describe what 1,000 words may have difficulty with, click on the following link, which shows the effect that the drought is having on reservoirs in California.

EVIDENCE OF PAST MEGADROUGHTS


The tree ring sample below is the direct evidence of the 'natural' cycles of historical mega droughts, and provides enough evidence to forecast future mega droughts. If California does not get ready and plan for this, there could be massive suffering and consequences. But this natural megadrought cycle does not include human caused global warming, which will only make the next (or present day?) megadrought cycle worse, according to several university studies, detailed below. Why will the next (or present) megadrought be worse?



SNOWPACK DISAPPEARING, PROVIDES MOST DRINKING WATER

Due to global warming around the world, glaciers and snowpacks in the mountains are disappearing. Historically, these glaciers and annual snowpacks melted gradually over the spring and summer months, providing a stable and dependable source of drinking water for cities, as well as for agriculture, industry and animal raising. 

Mega drought in West? Dry conditions increasingly worsen (more details about snowpack and relationship to water supply in the following video)

Fresh water sources are shrinking or disappearing due to a combination of global warming which is causing the receding and disappearing glaciers, plus little or no snowpack during the winter months. The end result is less and less fresh water that can be safely stored and used.

WILDFIRES ACCELERATING AND GROWING LARGER, LONGER AND MORE SEVERE


Reservoirs are down to between 30 or 17% of normal or this time of year. Wildfires are happening in January, 2014, which is supposed to the rainiest and wettest part of the year, with 0 fires in 2013, but over 400 in 2014. As Michio Kaku said, this is "the drought from Hell", worse than anything seen up to the 1800's. He calls this a potential catastrophe, or a train wreck in slow motion. 



WHAT IS A MEGADROUGHT?


Wikipedia; "A megadrought (or mega-drought) is a prolonged drought lasting two decades or longer. Past megadroughts have been associated with persistent multiyear La Niña conditions (cooler than normal water temperatures in the tropical eastern Pacific Ocean).[1] The term megadrought is generally used to describe the length of a drought, and not its acute intensity. 

In scientific literature the term is used to describe decades-long droughts or multi-decadal droughts. Multiyear droughts of less than a decade, such as the Dust Bowl drought of the 1930s, are generally not described as megadroughts even though they are of a long duration. In popular literature multiyear or even single year droughts are occasionally described as megadroughts based upon their severity, the economic damage they inflict or other criteria, but this is the exception and not the rule.

Megadroughts have historically led to the mass migration of humans away from drought affected lands, resulting in a significant population decline from pre-drought levels. They are suspected of playing a primary role in the collapse of several pre-industrial civilizations, including the Anasazi of the North American Southwest,[2] the Khmer Empire of Cambodia,[3] the Mayan of Mesoamerica,[4] the Tiwanaku of Bolivia,[5] and the Yuan Dynasty of China.[6] The African Sahel region in particular has suffered multiple megadroughts throughout history, with the most recent lasting from approximately 1400 AD to 1750 AD.[7] 

North America experienced at least four megadroughts during the Medieval Warm Period.[8]

HISTORICAL EVIDENCE

Montezuma Bald Cypress tree, 900 years old

There are several sources for establishing the past occurrence and frequency of megadroughts, including:

When megadroughts occur, lakes dry up and trees and other plants grow in the dry lake beds. When the drought ends the lakes refill, when this happens the trees are submerged and die. In some locations these trees have remained preserved and can be studied giving accurate radio-carbon dates, and the tree rings of the same long dead trees can be studied. Such trees have been found in Mono and Tenaya lakes in California, Lake Bosumtwi in Ghana; and various other lakes.[9]
http://en.wikipedia.org/wiki/Megadrought

TREE RINGS PROVIDE EVIDENCE OF MEGADROUGHTS


Dendrochronology, the dating and study of annual rings in trees. The tree-ring data indicate that the Western states have experienced droughts that lasted ten times longer than anything the modern U.S. has seen. Based on annual tree rings, NOAA has recorded patterns of drought covering most of the U.S. for every year since 1700. Certain species of trees have given evidence over a longer period, in particular Montezuma Cypress and Bristlecone pine trees.

UNIVERSITY OF ARKANSAS PROVIDES MORE EVIDENCE


The University of Arkansas has produced a 1,238-year tree-ring based chronology of weather condition in central Mexico by examining core samples taken from living Montezuma Cypress trees.

UNIVERSITY OF REGINA RESEARCHER SAYS IT COULD GET MUCH WORSE


But University of Regina paleoclimatologist Jeannine-Marie St. Jacques says that decade-long drought is nowhere near as bad as it can get. St. Jacques and her colleagues have been studying tree ring data and, at the American Association for the Advancement of Science conference in Vancouver over the weekend, she explained the reality of droughts. "What we're seeing in the climate records is these megadroughts, and they don't last a decade—they last 20 years, 30 years, maybe 60 years, and they'll be semi-continental in expanse," she told the Regina Leader-Post by phone from Vancouver.

MEGADROUGHTS DOCUMENTED IN CALIFORNIA


During a 200 year mega drought in the Sierra Nevada that lasted from the 9th and 12th centuries, trees would grow on newly exposed shoreline at Fallen Leaf Lake, then as the lake grew once again, the trees were preserved under cold water. [11]

NORTHERN ARIZONA UNIVERSITY RESEARCHERS SAYS SOUTHWEST MAY BE HEADED FOR MEGADROUGHT


Two Northern Arizona University researchers have dug deep into the past to determine what the future may hold for water availability in the southwestern United States. For more on this, click on the following link..

Southwestern U.S. headed for ‘extended megadrought’
But, a new study recently published in the science journal, Nature, suggests the Southwest is headed for a mega drought. Scott Anderson was one of the researchers on the study. He's a professor of paleoecology and environmental sciences at NAU. He spoke with KNAU's Gillian Ferris Kohl about the study.

MORE EVIDENCE: ANCIENT SEDIMENT CORE SAMPLES PROVIDE EVIDENCE OF MEGADROUGHTS LASTING 100's TO 1,000 YEARS


Sediment core samples taken at the volcanic caldera in Valles Caldera, New Mexico and other locations. The cores from Valles Caldera go back 550,000 years and show evidence of megadroughts that lasted as long as 1,000 years during the mid-Pleistocene Epoch during which summer rains were almost non-existent. Plant and pollen remains found in core samples from the bottom of lakes have been also studied and added to the record.

Fossil corals on Palmyra Atoll. Using the relationship between tropical Pacific sea surface temperatures and the oxygen isotope ratio in living corals to convert fossil coral records into sea surface temperatures. This has been used to establish the occurrence and frequency of La Niña conditions.[10]

WATER WARS A REAL POSSIBILITY

When people get desperate, they do crazy things. What happens if and when a major city like Los Angeles or San Diego runs out of water during a megadrought, (as it will)? The article below goes into some of the issues involved in larger more severe droughts and megadroughts. What happens if small towns run out of water before the big cities, and they are located next to the aquaduct that carries water from their area past them to the big cities?

SUMMARY AND QUESTIONS


The question is; assuming that a 'natural' megadrought condition continues for 30, 100 or 200+ years or more, both in California and in other areas of the world, how many people can be supported with the MUCH smaller amount of water that can flow through the 'new normal' water system? 

What drastic changes would have to be made to minimize suffering, losses and maximize the number of people that can be supported? An obvious first step is to reduce water use through the largest variety of methods possible. A second and very simple strategy is to increase storage capacity of water that does arrive via rain, but at the building site, not behind dams.

A third strategy is to increase water saving through creative methods.

A fourth strategy is to increase creative means of creating and/or gathering more water from unusual sources. AGRP has the capability to do a pilot project around generating rain via other than chemical methods, using out of the box thinking and techniques that have proven successful in other countries. (Contact AGRP for more details.)

Assuming that sufficient winter rains do not arrive in 2014, RADICAL and QUICK changes will have to be made in many areas of California, as the water supplies in reservoirs run out. Absolute worst case, megadroughts may even mean mass migrations or emergency relocations of large numbers of people, and that also needs to be planned for as a contingency.

Having a contingency plan in place for worst case and starting to make preparations would be a prudent and conservative thing to do, correct? Wouldn't that be better than just hoping for a best case scenario? Doing nothing and wishing that everything goes back to normal does not work. Denial is ok, but that only works for so long.

IDEAS AND SOLUTIONS


Post any additional potential solutions or ideas in the comments section below, and AGRP will add that to this article...

To end on a positive note, some scientific climate modeling projections based on historical data show that more rain could fall in the future, combined with increasing temperatures. But no one knows for absolutely sure, so it is best to prepare and start taking actions towards the worst case scenario..
