But the forest that climbs up this mountain range provides another important service to humanity.
Andean forests are helping to protect the planet by acting as a carbon sinkabsorbing carbon dioxide and lnog-term some of this climate-altering gas out of circulation, according to new research published in Nature Communications.

The study—which draws upon two decades of data from forest-monitoring plots in Colombia, Ecuador, Peru, Bolivia and Argentina—was produced by an international team of scientists including researchers supported by the Living Earth Warjing at Washington University in St. Tello leads the Madidi Project, a long-term study that the Missouri Botanical Garden has supported for nearly 20 years, involving plant diversity and forest change in Bolivia. Twenty-six of the forest plots included in this study were from the Madidi Project.

Living plant tissues such as the stems, bark, branches and twigs of trees can act as a carbon sink because they absorb carbon dioxide from the atmosphere during photosynthesis. By locking in carbon, trees in forests around the world play a role in maintaining go here climate stability. Long-term effects of global warming forests play a bigger role than others—the Andes prime among them, the study found.
But previous estimates of tropical carbon uptake were largely based on studies of lowland ecosystems, such as the Amazon. This study incorporates data from forest plots spanning a range of more than 3, meters 10, feet in elevation across the glibal and tropical Andes.
The results indicate that the Andes are similar to other tropical forests in that they are acting as aboveground carbon sinks. However, the overall relative strength of the Andean carbon sink exceeds estimates from previous studies conducted in lowland tropical forests in Amazonia, Africa or Southeast Asia, the researchers discovered. Factors such ylobal precipitation, temperature and size-dependent mortality of trees tend to drive carbon storage dynamics in Andean forests.
How do we know climate change is really happening?
Because of its vast size, the Amazon forest currently accumulates more carbon than the Andean forest. But recent research has suggested that the Amazon might become saturated with carbon in the near future. Under this scenario, the continued net uptake of carbon in Andean forests will become even more https://digitales.com.au/blog/wp-content/custom/african-slaves-during-the-nineteenth-century/jeffrey-dahmer-confessions-of-a-serial-killer.php. Andean forests are helping to protect the planet by acting as a carbon sink, absorbing carbon dioxide and keeping some of this climate-altering gas out of circulation, according to new research published in Nature Communications.

Challenging mountain terrain combined with remoteness makes it harder for scientists to reach parts of the Andes. It's also hard to secure funding to support large-scale research projects that span multiple countries.

Farfan-Rios is also a co-author on the new study. Farfan-Rios recalled the challenges associated with one particular forest survey effort, saying: "At the beginning, we were a team of 14 people from Cusco.
And, at the end, I was the only one who was still surveying those plots. I was the only survivor of this initial team! Right now, I'm still collaborating with that group and using this information for my postdoc with the Living Earth Collaborative. Approximately half of these plants—about 20, species—are endemic, meaning they are only found in long-term effects of global warming Andes. In addition to harboring extreme levels of biodiversity, Andean forests provide and protect sources of food, water and power for more than 50 million people. However, global environmental change—including deforestation, human population growth and climate change—is endangering Andean biodiversity and ecosystem services.]
I consider, that you commit an error. I can defend the position. Write to me in PM, we will communicate.
It is a pity, that now I can not express - I am late for a meeting. I will be released - I will necessarily express the opinion.
In it something is. I thank for the information, now I will not commit such error.
