The Great Mega Drought
The U.S. Southwest and Central Plains regions are likely to be scorched by a decades-long “mega drought” in the second half of this century if climate change continues unabated, scientists from NASA and Cornell and Columbia universities have warned.
In a study published by the journal Science Advances this week, the researchers forecast that future drought risk in the area is likely to exceed even the driest conditions experienced during extensive Medieval-era periods that have been dubbed “megadroughts.”
There is an 80 per cent chance of an extended drought between 2050 and 2099 unless aggressive steps are taken to mitigate the impacts of climate change, the article predicted.
Richard Seager, a senior researcher at Lamont-Doherty Earth Observatory of Columbia University, looked at 19 computer models of the future under current global warming trends. He found remarkable consistency: Sometime before 2050, the models predicted, the Southwest will be gripped in a dry spell akin to the Great Dust Bowl drought that lasted through most of the 1930s.
“Ultimately, the consistency of our results suggests an exceptionally high risk of a multidecadal megadrought … (and) a level of aridity exceeding even the persistent megadroughts that characterized the Medieval era,” the scientists wrote.
The researchers said their results point to a remarkably drier future, one that presents a substantial challenge and “falls far outside the contemporary experience of natural and human systems in Western North America.”

They said the number of people living in the U.S. Southwest and Central Plains, and the volume of water they need, had increased rapidly over recent decades and that these trends are expected to continue for years to come.
Future droughts will occur in a significantly warmer world, the study added, and conditions are likely to be a major added stress on both natural ecosystems and agriculture.
It said recent years have seen the widespread depletion of nonrenewable groundwater reservoirs.
“Combined with the likelihood of a much drier future and increased demand, the loss of groundwater and higher temperatures will likely exacerbate the impacts of future droughts, presenting a major adaptation challenge,” it said.
Ironically, the total economic cost of climate change in the United States will be major and nationwide in scope, but remains uncounted, unplanned for and largely hidden in public debate, says a study from the University of Maryland.
There is an increasing interest in the Canadian Prairie Provinces in regarding water as a commodity and selling some of it to pay for the development required to put the portion retained in Canada to use. We estimate an additional 600 m3s for Canadian use and a 600 m3s (19 billion m3) export to the Midwest at a fair auction price of .13/m³s. This means annual water export revenue of US$2.5 Billion/year from this canal alone.
Water is explicitly included as an “agricultural good” under article 711 of the Free Trade Agreement. If Canada diverts water to provide drought relief to Canadian farmers, we cannot discriminate against similar needs by U.S. farmers.
There are plans to build a $423 million 337-mile (542 km) long pipeline to distribute water from the Missouri River to water short citizens in South Dakota, Iowa and Minnesota for a roughly 5,000 square mile area, which is the size of Connecticut. By comparison, in Australia, they plan to build a 3700-kilometre canal (2300 miles) to bring water from the Kimberley to Perth.
The longer we wait, the more investment will be required and the more difficult it will become to make the needed changes. Everyone is just waiting, hoping that rain will solve the problem. There is no Plan B. We have to move now in our own prairie provinces before the real crisis while there is time.
HUG HYDRO ELECTRICITY We have developed the Proprietary HUG, which can become the power of future technology — the vortex power of water, which increases the velocity of the flow in HUGs by four times:
|Costs (Actual) Estimated|
|1987-89||Northern Plains: Drought Relief: $4Billion||$40 Billion|
|Summer 1993||Southeast U.S.||$1.0 (1.3) Billion|
|Summer 1998||Southern: from Texas/Oklahoma eastward to the Carolinas. Central Texas has been in a severe drought for nearly a decade.||$6.0-$9.0(6.6-9.9) Billion|
|Summer 1999||Eastern: Very dry summer and high temperatures, mainly in eastern U.S., with extensive agricultural losses||$1.0 (1.1) Billion|
|Spring-Summer 2000||South-central and Southeast states: losses to agriculture and related industries||$4.0 (4.2) Billion|
|Spring through early Fall 2002||Large portions of 30 states (40% of the nation): Moderate to Extreme drought including the western states, the Great Plains, & much of the eastern U.S.||Over $10.0 ($11-12) Billion|

OUR NORTHYDRO STRATEGY
Stage 1 To introduce a smaller version of the HUG: for Fish and Hunting Camps
Stage 2 HUG Hydro electricity and irrigation in remote areas: to support work in Africa. Stage 3 To capture energy from Run of River, Rapids and Waterfalls with the HUG
Stage 4 To Introduce the HUG Water Transfer System to crisis areas
Stage 5 To introduce commercially viable HUG Tidal Energy
