Saguaro Near the Catalina Mountains

Tucson, High Desert – 2006

Across the desert floor saguaros bake in the hot, dry air. It is the time when the saguaro fruit sets and ripens. Birds, bees, javelinas, coyotes, bobcats – and people – dine on the sweet red fruit. The Desert People will make syrup or jam and ceremonial wine for the rain dance inviting the wind and clouds to bring the precious gift of water once more.

After the harvest is the time of waiting and watching. We see voluminous clouds pile up over the mountains – swirling dark clouds over a living desert. Even their shadows cast welcome relief.

We wait … immersed in an ocean of heat. We sweat and burn in light that cuts like a hundred blades into unprotected skin. On the Fourth of July midtown rockets burst on an obsidian sky while desert creatures prowl in the cool moonlight.  This day marks the arrival of the monsoon. Even the word, its utterance, a desert dweller’s mantra, offers relief:  monsoon!

And then it happens … the first dollops of rain splash down! Perhaps we see it far across the valley falling in just one particular area. We are jealous, but encouraged, for we know that soon it will fall on us, too. Our lives are made more certain with the rain. No creature can live without this precious rain. No, none.

The summer rhythms of this desert remind us of our vulnerability. That is the gift of the Saguaro season. We are dependent. Humbly we may realize it. We stand outside like fools and let it fall on us, run down our faces and spine where its coolness makes us shiver when only a second ago we were sweltering.

People in their cars, navigating flooded intersections, are amused. In washes, valleys and hillsides the shallow roots of columnar cacti, the ancient trees of our land, pump in the crystal substance as it trickles or gushes through the sand and stone. Their fluted forms expand with the tidal rhythm.

It is a desert baptism among people who still appreciate the desert’s rhythmic character. They catch rainwater in barrels and dig wide basins in the earth to hold the precious rain and prepare the soil for native seeds saved from last year’s harvest of squash, beans, corn, melons, and greens. They collect the mesquite beans and pound the pods into sweet flour to make bread that heals the body.  The harvest is bountiful when the gardening is blessed and prayers go forth in gratitude and hope.

When the big clouds roll up from the Gulf of California, the old women lift their harvesting sticks to pull down the clouds and bring the rain. The Tohono O’odham, The Desert People, keep vigilance over the city and the land around it and even the Europeans are learning to pray, in their own way. The Mexicans and Spanish have always kept the seasonal rhythms of land and seed and they pray to their spiritual guides, and all together raise their faces in prayerful patience as the clouds move up from Mexico over the Santa Catalinas swirling dark and black over the Old Pueblo. Somewhere I imagine there may also be a jaguar looking up in want of rain.

Sonoran Desert

Phoenix, Low Desert – 1999

At midnight the heat radiates from the cement driveway under my feet. I stand in the white moonlight gazing up at twinkling stars. The dark outline of tall trees and roof tops form a stage-drop where city glow breaks the blackness of night.

This is my summer ritual: star-gazing in my pajamas. I wake out of some consciousness that tells my snoozing brain I can open the doors and go out to a cool 90 degrees. I lay in a chaise lounge in the middle of the driveway under a sparkling dome of heaven. The air is gentle, warm, caressing. Like other desert creatures, I have become nocturnal. The moon is my muse.

It’s summertime in Phoenix, Arizona. Temperatures soar over 110 ̊. After June, the buildings and streets absorb the day’s solar energy and then slowly release it through the night. Even though the sun goes down, the built environment radiates like an oven.  The hum of air conditioners is a constant auditory feature of modern desert life.

In the old parts of town residents open aqueducts in their yards. Encircled by an earthen berm, the lawns hold the precious ground water releasing it slowly to soak deeply into the sandy soil and keep their urban lawns green. In the 1900’s people moved to the desert for its dry climate and to escape allergy-causing vegetation. However, the mulberry and olive trees they imported with them resulted in Phoenix becoming the asthma capital of the west by 2000. The average low temperature has increased by 10 ̊ in just 40 years—the result of miles and miles of asphalt and concrete which act like a heat sponge.

Native trees have been reduced by introduction of non-natives (exotics) like the Tamarisk tree in areas where the water table once ran close to the ground. For thousands of years these habitats supported the greatest species diversity in the state.  Beavers and otters abound in rivers and streams, and fauna like deer and Coati mundi inhabited native forests. Memories of Arizona’s extensive green belts have faded with each new generation. Who will remember what has been lost?

Gazing at the twinkling night sky above me, I imagine the ancient Hohokam people—who laid down the original grid of canals still in use today— how they, too, must have lain outside in the cool of moonlight thousands of years before me. Did they work and cavort at night like the desert’s creatures, and sleep in the cool of their adobe huts, or under a shady ramada of reeds, during the blistering heat of daytime? What happened to their great city and 200,000 inhabitants? Why did they leave this valley and its two rivers, the Salt and the Gila, leaving only their canals behind?  Am I part of a Great Reenactment?

I watch the dark outline of a big, brown bat drinking nectar from a tall saguaro’s bloom in my neighbor’s yard. Afar I hear coyotes yipping from a hilltop in a suburban sea. In the wee hours of the warm, dry night, I drift into a deep sleep under a canopy of stars.

Places – Imperial Valley

Yuma, Arizona Farm Fields

Imperial Valley, Below Sea Level, 1990

The Colorado River was a wild, red fury in its natural state. It flooded its banks in southern Arizona and Northern Mexico on its way from the Rockies to the delta on the Sea of Cortez, Gulf of California. This was true for thousands of years. Early people learned its rhythms and developed cultures in sync with the river’s seasonal flows. They are called The Colorado River Indian Tribes—distinct communities that still exist along the river’s course. Their history encompasses the dramatic changes wrought by damming the great river to create one of the most extensive desert gardens known to humankind.

When I crossed the Continental Divide atop the Laguna Mountains, under a brilliant star-studded black sky, I was entering a dimension so subtle it would take me years to define it. Something more than gravity pulled me down the steep, winding road as it descended into the Imperial Valley. The sun was just breaking above a distant horizon as my vehicle finally leveled out onto the valley floor. Immediately an aroma of soil, mist, and something close to boiled peanuts filled my nostrils. It is a scent that I have only experienced in this part of the U.S. – distinct and overtaking. It is not unpleasant but haunting in a way. You know it is not natural for the valley but something created by a great deal of struggle, sweat, and industry.

In the far distance a range of ruddy red mountains formed the eastern border of the valley with Picacho Peak soaring into unbroken blue. I recall my daughter’s reminiscence after moving to Washington, D.C. from Arizona: “Mom, I miss that big dome of sky that made me feel protected under its blue canopy.”

Openness, expansion, mystery and fear were the emotions that churned in me that day.

The Imperial Valley stretches over 100 miles from the foothills of the Laguna Mountains in southern California to Yuma, Arizona at the juncture of California, Arizona and Mexico. It is a vast alluvial plain, rich in minerals and, before the irrigation of the valley, a low desert dotted by barrel cactus and rolling tumbleweed. Once the dams and extensive canals were built (a colorful history of drastic measures, tragic mishaps, and powerful men with big dreams and money to back them) the desert floor flowered into one of America’s most productive bread baskets. In 1990 the lettuce crop alone harvested $16M for growers.

As the sun rose higher, row upon row of lettuce and blue canals appeared and disappeared from view like an old-time flickering movie. Egrets and gulls flew above or walked among the rows! Did they migrate from the oceans of southern California or up from the delta on the Sea of Cortez?The whole experience was surreal. Then I began to notice the heat…oh, dear. My un-air-conditioned beach mobile! I was unprepared for this region of the world. I was sweating profusely now and had brought only a small bottle of water with me. Suddenly I felt threatened. Where was the nearest town?  Where were the people? I saw nothing but huge sprinklers like warriors from Star Wars on thin metal legs rolling across fields throwing streams of precious Colorado River water onto American grown vegetables and cotton. On and on I drove, past a feedlot that stank for miles, past an ostrich farm and more green flushed with blue sparkling water. Was there any water left in the Rio Colorado? I wondered.

The heat grew ever more oppressive. At below sea level, the Imperial Valley is a heat sponge. I nearly fainted before finding a small town and limped into Wendy’s where I remained for three hours slumped over a table. The waitresses were empathetic. Many California beach combers succumbed to the valley’s record temperatures. It reached 119 degrees that day in May.

PLACES

Okefenokee Wildlife Refuge

Places define much of what we become and in myriad ways determine the things we do.  Far from a “backdrop” to the drama of our lives, the places we inhabit, grow to love, and defend fiercely as we would our children, are intimately a part of us.  We breathe their air, drink their waters…eat from the table of their mantles until they form our flesh and blood and point of view. In turn our breath is taken up in tree trunks and leaves and our excrement is filtered into the earth. Our voices can be heard moving over the land where they mingle with the buzzing hordes and songs of feathered choruses. We are not apart from a place but knit tightly into it in mutual exchanges. We are relations.

My family history begins in the Smoky Mountains where many Irish, Welsh, and Scottish immigrants settled. Although I was born there, at the end of WWII my father returned to the States and whisked up my family into a 16-year journey of military life. We moved from coast to coast in the U.S. with one gentle, magical time in Honolulu on Oahu. It would not be a State of the U.S.A. until 1959, years after we left.

Changing places frequently lends to a sense of loss and confusion precisely for the reasons that place is not a location but the source of our biological and psychological lives. I am only now beginning to appreciate this fact, now looking back. As hard as it was to be continuously uprooted and thrown upon new soil, I learned to grasp hold quickly and savor the rich, diverse places on my “dance card” in life.

World Waking Up to Climate Change

In the past few days we have learned that major investors and businesses are getting in step with climate action. BlackRock investing firm announced they would no longer invest in businesses that are not meeting climate change objectives.

“Awareness is rapidly changing, and I believe we are on the edge of a fundamental reshaping of finance,” Mr. Fink wrote in the letter, which was obtained by The New York Times. “The evidence on climate risk is compelling investors to reassess core assumptions about modern finance.” ~ New York Times 1-14-20

Microsoft announced a Net Negative carbon footprint plan to reduce its emissions and to eliminate its carbon footprint completely by 2030.

The scientific consensus is clear. The world confronts an urgent carbon problem. The carbon in our atmosphere has created a blanket of gas that traps heat and is changing the world’s climate. Already, the planet’s temperature has risen by 1 degree centigrade. If we don’t curb emissions, and temperatures continue to climb, science tells us that the results will be catastrophic. ~ Microsoft Commitment to Sustainability

IPBES Report on Biodiversity and Ecosystems

Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)
Summary PDF for Policy-Makers (and the public)

Biodiversity is a key driver of ecosystem health and resilience. The more variety of genes and groups of genes in a particular habitat (# and kinds of living plants and animals, invertebrates, etc) the greater is its resiliency to impacts such as climate change, and human development and habitation.

A good example can be seen in our coastal ecosystems where an abundance of grasses, landforms, certain trees, sea grasses and coral reefs, promote resiliency to storms, development, etc. Dense human habitation along coastal areas has polluted waters that kill sea grasses, result in erosion of beaches which once provided a barrier to incoming storms and sea level rise.

Read the report and chat with your local city council and with your representations. Send them this short summary report. summary_for_policymakers_ipbes_global_assessment
