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.

Ecologic disaster in Mexico

In the mid 1900’s, Mexico experienced an ecologic disaster created by the draining of the Colorado River at the USA/MX border. This left over 60 miles of riverbed devoid of moisture. The Colorado River had been depositing a huge volume of water into the delta and Sea of Cortez. The loss of this flowing water destroyed 3,000 sq-mi of wet, verdant, green land and created a 3,000 sq-mi parched, dry, brown desert. This change from green to brown is a local climate change. The humidity level is greatly decreased so the area can no longer contribute to its hydrologic cycle. The 3,000 sq-mi desert is now in a constant state of drought. This was the first domino to fall in the domino-droughts.

Paris Accord

Implementation of the Paris Agreement requires nationally determined contributions (NDCs). Each NDC is meant to align with the Paris Agreement temperature goal, taking into account different national circumstances. In the NDC, countries take action to build resilience to adapt to the impacts of climate change.

What is Laguna Salada, Baja, MX.
Time lapse photography, 1984 to 2023, showing dehydration of Laguna Salada, Baja, MX.

Laguna Salada is a below-sea-level depression just north-northwest of the Colorado River delta has been filled with salt water. Laguna Salada was being kept full by the now drained Colorado River and moisture evaporated from the previously green delta. In 1999, with the Colorado river being dry south of Mexicali, Baja, MX., and the delta a desert; Laguna Salada went completely dry. The domino-droughts began in 2000 and morphed into the current mega-drought.

What Is The Easy Opportunity?

Fill Laguna Salada with ocean water from the Sea of Cortez. Reversing the Coyote Canal and refilling Laguna Salada will meet the Paris Accord NDC goal. 

Why Is This Easy?

Visualize the Coyote Canal as a nice wide water path from the Sea of Cortez into Laguna Salada.

The Coyote Canal is an existing water path between Laguna Salada and the Sea of Cortez. This dry creek bed was straightened and shortened in recent years. The work that needs to be accomplished today is to make that canal deeper and wider 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 rainwater 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…

Wherever 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…

This will add moisture to the Colorado River delta because of the flow from the ocean through the delta to Laguna Salada. this moisture will aid in rehydrating the Colorado River delta.

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.
