Mexico Holds One of the Keys to Reversing Climate Change.

Unfortunately…

Mexico has not used that key and the solution remains securely locked. Mexico has expressed a commitment to helping solve Climate Change by their signing the Paris Accord, but seems oblivious to this easy opportunity which only they can accomplish.

What is this easy opportunity?

Fill Laguna Salada with ocean water from the Sea of Cortez.

What is Laguna Salada?

Laguna Salada is a below-sea-level depression which until recently has been filled with salt water.

Why is it dry?

In the past; Laguna Salada has been filled by water from the Colorado River. In recent years people have found more and more uses for the Colorado River water which inhibits the refilling of Laguna Salada because the Colorado River water is diverted before can arrive at Laguna Salada. See time-lapse video of Laguna Salada from 1984 to 2017 which illustrates the total loss of all water over time.

Why is this an easy opportunity?

Move the Water! into Laguna Salada from The Sea of Cortez.

There is an existing water path between Laguna Salada and the Sea of Cortez. This water path (dry creek bed) was straightened and shortened in recent years. The work that needs to be accomplished today is to make that canal deeper so that the non-existing out-flow from Laguna Salada is reversed to an in-flow from the Sea of Cortez. The effort required to is minimal because the canal already exists, its path is defined, and its length is about 60 miles (120 kilometers). There is minimal excavation required.

How does this help reverse Climate Change?

The first thing…

The first thing it accomplishes is a reduction of the ocean level. The oceans are rising because of the melting of the glaciers. The water that melts off them can flow into Laguna Salada. Any water which flows out of the ocean into Laguna Salada is water which is not in the ocean anymore, so the ocean level is lower.

The second thing…

The second thing is that Laguna Salada is located in a very hot, very dry, very windy place. This means that the water in Laguna Salada will evaporate quickly and be carried away from Laguna Salada. As the water evaporates, the ocean level will be further reduced to refill Laguna Salada.

The third thing…

The third thing is that the water which evaporates into the atmosphere will be carried away from Laguna Salada. Water vapor carried east or west will return to Laguna Salada as rain water flowing down from the flanking mountains. Water vapor carried south it will return to the Sea of Cortez. Water vapor carried north it will indirectly replenish the Colorado River watershed; which will begin to reverse the mega-drought and help the whole Colorado River watershed and it’s the varied water users.

The fourth thing…

The evaporation of water from Laguna Salada should lower local ambient temperatures. According to the USGS; heat is removed from the environment during evaporation, leading to a net cooling. In climates where the humidity is low and the temperatures are hot, evaporation can lower the air temperature by 20 degrees F.

The fifth thing…

Where ever the evaporated moisture falls it will encourage plant growth. Plant growth will help heal the atmosphere by absorbing carbon and by cooling the local environment.

The sixth thing…

Mexico holds part of another key…

After Laguna Salada is filled with sea water, a canal should be built north to the USA border so the USA can join with it and refill the Salton Sea. Refilling the Salton Sea continues all the above benefits to a second location.

  1. Best to use giothermal power to pump salten sea water to sea of cortez and pump clean water back from the sea as needed, with no danger of over flow.

    1. Using geothermal power requires the use of energy to create the geothermal energy. Use of energy generates unwanted exhaust into the atmosphere. In this case, the energy use would be ongoing for decades, constantly exhausting into the atmosphere.

      Conversely, creating an open gravity flow water path from Sea of Cortez to Salton Sea uses energy only in its creation, after that only gravity is used to Move the Water! This is sustainable for decades with no further energy use.

      Move the Water! also provides the opportunity to generate electric energy from the water flow. This type of energy does not pollute our atmosphere. If you wish to pump water from Salton Sea to circulate the water, this clean energy could be used for that task.

      1. The geothermal power plants located near Niland and Calipatria at the southern end of the Salton Sea work by tapping into super heated brine from the San Andreas fault.
        Once the immense pressure is released, this very hot and very salty water at temperatures of up to 600 degrees Fahrenheit, flashes into steam that then turns turbines and produces electricity.
        The byproduct seen escaping through vents is also steam (not smoke). Technically water vapor is a greenhouse gas. However, allowing extra water vapor in this region has positive benefits as mentioned in your article.
        Another added benefit of geothermal power plants along this portion of the fault line is the brine is one of the richest sources of Lithium in the world. This is the essential ingredient for Lithium ion batteries. Geothermal power plants can be retrofitted to capture Lithium from the brine during the steam collection process.
        Then the rest of the brine is allowed to return to the fault.
        This makes the combination of geothermal energy production and Lithium extraction the most environmentally friendly on the planet.
        It is difficult to find any downside to this.

  2. Work with Cucapah people to create salt-water fishery, bird habitat and jobs for local people. Use gravity for the connection to the Sea of Cortez. Avoid large amounts of construction use whatever is in place. What is the minimum required to get this going?

    1. You ask: < What is the minimum required to get this going? >
      That is an excellent question. I guess the minimum would be to get the concept into public discussion so more know of it and can see its benefits. Ultimately it will take recognition and action from the Federal Governments that this must be done, but they will not act unless they are pushed to do so by public awareness and comments.

    2. The Laguna Salada would make a great stepping stone towards revitalizing the area between the Colorado River Delta and the Salton Sea.
      The importation of sea water to save the dwindling Salton Sea has been shot down for now. However, on the Baja side, Laguna Salada would make a suitable backup site.
      It is much closer to the Sea of Cortez and is 9 feet below sea level. It also is along the path of the Colorado River Delta (when there is enough water to flow this far).
      I have read that at very high tides in the northern Gulf of California, that Laguna Salada fills with sea water temporarily.
      This would be an easy solution to offset water loss in the Salton Sea and provide migratory birds with habitat.

  3. Whether or not Mexico invests in getting this project done will eventually be a mute point.
    As the sea continues to rise, the very fact that Laguna Salada is below current sea levels by something like 9 feet, will ultimately result in a net inflow once the slight elevation of topography just north of the Sea of Cortez is eroded.
    In addition, the Pacific Plate boundary is directly below this entire area. Though technically the San Andreas fault doesn’t start until the middle of the Salton Sea near Bombay Beach, a rift by another name still exists under Laguna Salada and the Colorado River delta.
    Frequent earthquakes with epicenters all along this section are working to extend the northern reaches of the Gulf of California. The depressions that Laguna Salada and the Salton Sea inhabit are just further evidence of this process.
    If another large magnitude earthquake like the one from Easter Sunday 2010 were to occur between the northern shores of the Sea of Cortez and Laguna Salada, it would most likely result in an unchecked flood of ocean water.
    If you look at a topographic map of the area, once the loose alluvial deposits are breached just north of the Sea, it is all downhill from there until somewhere in the southern part of the Coachella Valley.
