This project revolves around how the human action has changed the world in an unstoppable tide, centered on the effects on mountain ranges¹ and developed as a dialog between generations, taking the photographs that my father took in the 70s to talk about the present day. Humans have fundamentally altered global patterns of biodiversity and ecosystem processes, replacing themwith new ones of anthropogenic origin². Mountain areas and specifically glaciers are a very sensitive component of the biosphere³.

Alexander von Humboldt analized he data on humidity, temperature and plant species that he recorded at different altitudes as he climbed with Aimé Bonpland to the summit of Chimborazo⁴. Shortly thereafter, he organized the temperature data in the different regions of the planet and created the first isotherm map (lines of equal temperature), which inspired the creation of isobars (lines of equal atmospheric pressure) and prompted the birth of a new climate science. It was at the end of the 20th century that some researchers began to reveal an unexpected and disturbing reality. Human activity was shifting some of those lines, especially those that have to do with life. The increase in temperature due to our emissions, the invasion of ecosystems and our conflicts are altering the configuration of the planet on a scale never seen before.

The intense bombings of World War II changed the height of the ionosphere⁵ and nuclear tests carried out during the following decades altered the atmospheric configuration and even moved the Earth's radiation belts⁶. Our CO2 emissions are contributing to the acidification of the ocean and the line that marks the acidity level that prevents the formation of shells of millions of microorganisms is moving at an accelerated rate. These critical zones, which are generically known as “saturation horizons”, have moved by 50 to 200 meters compared to the levels they were at the beginning of the 19th century⁷.

A few years ago, upon returning to Chimborazo and reviewing Humboldt and Bonpland's data, a team of researchers discovered that, two centuries later, the lines marked by the two naturalists had also shifted⁸. The growth limit of many of the plant species they had documented in 1802 had risen more than 500 meters, from 4,600 to 5,185 meters. On Teide, a team of Spanish researchers recently discovered that the violets documented by Humboldt as he passed through Tenerife in 1799 had also risen from 3,300 to 3,700 meters, a 400-meter upward race that will soon leave them with no room to escape⁹.

Observations show general decline in the cryosphere (snow, glaciers, permafrost, lake and river ice) due to climate change in recent decades. The cryosphere is an integral element of high mountain regions, which are home to roughly 10% of the global population. Widespread cryosphere changes affect physical, biological and human systems in the mountains and surrounding lowlands, with impacts evident even in the ocean¹⁰.

This process embodies to me the expression of how unconsciously we are immerse in the irrefrenable change of the planet's face. About the glaciers in the Patagonia, a journalist¹¹ recently wrote: “The hordes of visitors who celebrate every time a huge chunk of the imposing Perito Moreno glacier breaks off, ignore the danger for the inhabitants of El Chalten that the imposing ice mass is retreating at full speed due to the impact of climate change.” More recently, a huge portion of a glacier in the Swiss Alps has broken off from the mountainside, sending rock, mud and ice crashing onto the village of Blatten¹². There are no reports of casualties, although the village of Blatten is now largely buried under rubble. “Nature is stronger than man. The mountain people know that. But today we experienced an extraordinary event. The event has left us speechless, and it’s shocking to see the images,” said Federal Councillor Albert Rösti.

At the heart of Vallibierna, where just a few hikers seeked for isolation in the wilderness half a century ago, now massive race trails take place¹³. The romantic myth of the victorian explorer has decayed as these unknown regions, the wilderness, have disappeared. There are no ‘Hic sunt Draconis’ left and these glaciers don’t exist anymore.
