Fog is a low-lying cloud and its moisture is generally locally generated. Fog appears when water vapor condenses into tiny droplets that are suspended in the air. It is highly influenced by nearby bodies of water, wind and topography. According to the generally accepted definition, fog reduces visibility to less than one kilometer. Giants redwoods, the biggest and oldest trees on the planet, receive almost 40% of their moisture from coastal fog through fog drip. Insects depend on wet fog as their principal source of water.

In particularly dry regions where rain is rare or non-existent, like along the Peruvian coastal region, in Mexico, Bolivia, Colombia, people have been trying to catch - to harvest - water from fog using mesh strung up on hillsides. Tiny droplets condense on the netting and dribble down into pipes that carry the water into containers where it can be used to irrigate crops or even as drinking water. Each net can capture between 200 and 400 liters of fresh water per day. More technologies are being developed. For instance, two Chilean architects are developing fog harvesting towers to collect water as high as possible in the fog.

Cloud forests or water forests are generally tropical or subtropical moist forests characterized by a frequent, persistent or seasonal low-level cloud cover, usually at the canopy level. Cloud forests are amongst the most biodiversity rich ecosystems, with a large number of species directly or indirectly depending on them. Only 1% of the woodland consists of cloud forests. In the 1970’s they comprised over 11% of all tropical forests. A total of 736 cloud forests have been identified in 59 countries by the UN’s World Conservation Monitoring Center. Half of these cloud forests are located in Latin America. Because of their dependency on local climate, these forests are affected by climate change. It would greatly impact species living in those areas like frogs and lizards, for example and cause the extinction of species.

Fireflies belong to the family of beetles that has more than 2,000 species, most of them light emitting. They produce light, through a chemical reaction inside their abdomen, primarily at dusk, to attract males. They live in marshes or in wet and wooded areas where their larvae find abundant food. Moist atmospheric conditions are very important for them to thrive. Fireflies have attracted humans since ancient times. Japanese have a particular reverence for fireflies and have set aside parks specifically for them, called hotaru. There is even a festival of fireflies each year in June. In poetry, they are a metaphor for passionate love.

When looking at the skyand all the aerial phenomena, we observed how artists through the ages had themselves looked at the sky and at the way light is reflected. We particularly loved looking at Japanese master Hiroshi Sugimoto’s “Seascapes”.  Shot in different parts of the world, always the same way, always in black and white, his photographs seem to fuse sea and sky and allow us to look at the Earth as a meditative experience

Wind is the natural movement of air or other gasses. It is caused by differences in atmospheric pressure which are mainly due to temperature differences. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area resulting in winds of different speeds. The two major factors of large scale wind patterns are the differences in heat between the Equator and the Poles and the rotation of the planet. In arid climates, winds are the major source of erosion. But a positive role the wind plays is in seed dispersal. Seeds can float on the breeze or flutter to the ground.

Seeds are the embryonic stage of a plant’s life cycle. It is often contained within a fruit to help its spreading. Seeds serve several functions for the plants that produce them. Key among these functions are embryo nourishment, dispersal to a new location, and dormancy when growth stops during unfavorable times. Plants have evolved in many ways to disperse their offspring by dispersing their seeds - by wind, by water, by animals (for instance, seeds with hooks which attach to the fur or wool of animals). The seed we have embroidered on some of the garments is the Starflower - or Lomelosia stellata. Also known under the name Scabiosa stellata, it is native of southwestern Europe. The name Scabiosa is derived from the latin word ‘Scabere’ which means “to scratch”. It is found in abandoned fields, roadsides. Seeds from starflowers are dispersed by wind.

Rain water is droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water. Global warming is causing changes in the precipitation patterns globally. Current climate models indicate that rising temperatures will intensify the Earth’s water cycle, increasing evaporation. Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. The fine particulate matter produced by car exhaust and other human sources of pollution forms cloud condensation nuclei, leads to the production of clouds and increases the likelihood of rain. In some parts of the world, changes in atmospheric humidity and heat caused by climate change are expected to increase the intensity and frequency of extreme weather and flood events caused by atmospheric rivers.
