Earth's Driest Desert now has Flowers Thanks to Climate Change

The driest desert, now adorned with a breathtaking array of flowers, is a sight to behold. This unexpected transformation, sparked by the rare occurrence of rains in North Chile, has turned a portion of the Atacama desert into a canvas of white and purple blooms.

Researchers have uncovered a fascinating link between these blooming plants and climate change. The sight of plants in full bloom in the middle of winter, a rare occurrence in the Atacama Desert, adds to the intrigue.

Some claim that the unusual bloom results from rain in North Chile during the fall season in the Southern Hemisphere.

A local term for morning fog, "camanchaca," along with approximately 0.4 inches (11 millimetres) of rain, fell in mid-April and sparked plants that can remain dormant for up to 15 years. The white "sighs of the field" and the vivid fuchsia-coloured "pata de guanaco" flowers were the species that created the scene.

The flowering mainly occurred in areas ranging from 115 to 155 square miles. César Pizarro, the head of Scientific Research and Biodiversity Conservation at the National Forestry Corporation (Conaf) in Atacama, affirmed this.

When about 200 different types of flowers bloom, a full flowering desert can often cover 5,800 square miles and occurs primarily between September and October due to winter rainfall.

Most of the time, flowers bloom in the spring, July, August, and June. The El Nino effect, which raises precipitation in Chile above average, is mostly to blame.

There was a lot of blooming a few years ago in 2015 when there were rains in March, but it's unclear if it will happen this time. Experts predict that before La Nina arrives, this state will persist for one additional month.

Regardless, if La Nina strikes again, these flower patches might be the only ones to appear this decade. The Atacama desert's uncommon winter flowering also raises issues.

Government's Actions on the Flower-Covered Desert

According to sources, Cesar Pizarro, the head of biodiversity protection at the National Forestry Corporation (CONAF), a government-run institution in Chile, said that the blooms are not yet widely distributed enough to be officially included in the "flowering desert."

However, he noted that more rain is predicted, which means the blossoms might disperse farther.

In 2022, the Chilean government announced the establishment of a new national park in the Atacama desert to preserve these uncommon blooms and the fauna they sustain, such as insects, reptiles, and birds.

Flowers Also Bloom in Antarctica

Scientific research last year found that one of the elements mentioned for the flowers' blossoming, climate change, was also why flowers grew in Antarctica.

The two blooming plants in question, the Antarctic Hair Grass (Deschampsia antarctica) and the Antarctic Pearlwort (Colobanthus quitensis), are native to Antarctica. Their growth rates have increased dramatically due to rising temperatures, which are primarily attributable to human activity.

According to reports, these activities led to an unparalleled rate of warming of the Antarctic terrain. Sources at the time indicated that Antarctica's distinct ecosystem- distinguished by its harsh circumstances and sparse biodiversity- is perfectly adapted to the harsh environment of the continent.

This delicate equilibrium, which has evolved over centuries, is now under threat. The rapid shifts caused by climate change could lead to lasting ecological harm, a prospect that should concern us all.
