Assistant: Title: Kiel sahara polvo nutras la amazonan arbaron
Caption: The Sahara Desert
is one of the least hospitable climates on Earth.
Its barren plateaus,
rocky peaks, and shifting sands
envelop the northern third of Africa,
which sees very little rain, vegetation, and life.
Meanwhile, across the Atlantic Ocean
thrives the world's largest rainforest.
The lush, vibrant
Amazon basin, located in northeast South America,
supports a vast network of unparalleled
ecological diversity.
So, what do these seemingly different climates have in common?
They are intimately connected by a 16,000 kilometers long
intermittent atmospheric river of dust.
Every year,
intense Saharan winds  send enormous clouds of dust
on a trans-Atlantic journey to the Amazon basin.
This dust, much of it originating in an ancient lakebed in Chad,
is rich in phosphorus.
When it reaches the rainforest,
the remains of long-dead organisms of the Sahara
provide crucial nutrients to the rainforest's living flora.
Phosphorus, which is essential to plant growth,
is in short supply in the Amazon.
Desert dust dumped into the forest
every year helps to diminish this deficit.
NASA researchers are studying this link
between Amazon and Sahara,
to understand how it operates
and how it might be affected by climate change.
Data from the french-american satellite CALIPSO
launched in 2006,
helped us to answer a few questions.
For the first time, CALIPSO has quantified the amount of dust
that makes the trans-continental voyage
and the numbers are impressive:
of the 200 million metric tons
(or nearly 700,000 semi trucks' worth)
of dust that leave the Sahara each year,
30,5 million tons, or 15% of the total
are scattered over the Amazon basin.
Creatures of the Amazon
and perhaps around the globe
may want to consider sending the Sahara a thank you.
