Amazon Rainforest Water Cycle at Risk: Urgent Measures Needed to Prevent Collapse by 2050
In a groundbreaking study published in Nature, scientists reveal alarming findings about the Amazon rainforest’s water cycle, emphasizing the urgent need for action to prevent its collapse by 2050. The focus keyword “Amazon” takes center stage in highlighting the critical issue.
The research, led by ecologist Bernardo Flores and his team at the University of Santa Catarina, identifies multiple stressors, including warming temperatures, extreme droughts, deforestation, and wildfires, that are intensifying and causing water stress in the forest. Flores emphasizes the severity of the situation, stating, “It can reach a point where the forest is no longer capable of persisting.”
The Amazon, home to about 10% of the world’s land-based biodiversity, plays a crucial role in storing carbon and acting as a carbon sink. However, the study warns that pushing the rainforest past its limit could accelerate climate change and have devastating consequences for local communities, particularly Indigenous groups dependent on the forest.
With approximately 15% of the Amazon already lost, Flores underscores the urgency of the situation, stating that losing an additional 10% could trigger a large-scale tipping point. Areas once lush rainforests could resemble landscapes akin to the U.S. Midwest, as seen by researcher Ernesto Alvarado in his past studies.
The study aligns with previous research indicating that the Amazon could become unstable with a 2-6 degree Celsius rise in global temperatures above pre-industrial averages. However, the new study adds spatial detail, pinpointing specific locations at the highest risk by 2050.
The silver lining lies in limiting warming to 1.5 degrees Celsius, aligning with the goal of the 2015 Paris climate agreement. This, the study suggests, could provide a safety margin to prevent ecosystems from transitioning away from the forest.
The focus keyword “Amazon” is strategically placed throughout the article, underlining the importance of this environmental crisis. The time for action is now, as the Amazon’s water cycle hangs in the balance, and the consequences of inaction could be irreversible, leading to the loss of numerous species and a shift from carbon sink to emission source.
