Amazon’s drought raises concerns of an impending tipping point for the Rainforest

amazon drought

The Amazon rainforest, often referred to as the lungs of the Earth, is facing a severe drought in Brazil that has far-reaching consequences. The dry spell, the fourth in less than 20 years, has damaged the forest ecosystem. This has led to depleted rivers, and fuelled wildfires, enveloping the region’s largest city in smoke. As the Amazon basin contributes a significant portion of the world’s freshwater, the ongoing drought is triggering concerns among scientists about a potential tipping point that could irreversibly alter the rainforest.

The term “tipping point” was introduced by climatologists Carlos Nobre and Thomas Lovejoy in 2018, emphasizing the impact of environmental destruction. It includes deforestation, climate change, and fires, on the Amazon. Their research suggested that maintaining 20% to 25% of the Amazon intact is crucial to prevent portions of it from transforming into a drier ecosystem resembling a savannah.

What is causing the Amazon drought?

Deforestation, exacerbated by global warming, has been identified as a major contributor to the current crisis. Models indicate that if global temperatures exceed 3.5 degrees Celsius above pre-industrial levels, the Amazon could reach a tipping point. It could lead to widespread die-off, independent of tree cover loss. A significant portion of the Amazon has already been lost, with 13% of the original rainforest disappearing since European colonization. The eastern part, particularly vulnerable, has lost 31% of its forest cover. Additionally, 38% of the Amazon has been degraded, indicating a decline in resilience, especially in the “arc of deforestation.”

The current drought, potentially worse than the 2005 event, has led to record-low river levels and increased concerns about the region’s drying conditions. The city of Manaus experienced the lowest Rio Negro level in 121 years.

The repercussions extend beyond the immediate environmental crisis. The Amazon, currently a carbon sink, could become a net carbon emitter if too many trees die and rot. This can exacerbate climate change. The 2005 drought resulted in the forest emitting more greenhouse gases than the annual emissions of Europe and Japan combined.

Efforts in motion

While some researchers argue that certain parts of the Amazon may have already reached a tipping point, efforts are underway to mitigate further damage. Suggestions include designating unprotected public land as environmental reserves or Indigenous territories and restoring 6% of the forest’s original area. Despite a recent drop in deforestation rates, Brazil’s commitment to reforesting 12 million hectares by 2030 faces challenges. Estimates indicate that substantial investments are needed to fulfill this pledge. The fate of the Amazon, it seems, hangs in the balance, with urgent action required to avert irreversible ecological consequences.

With even large forests like Amazon facing droughts, it is time for some quick and urgent action to combat climate change and the looming water crisis. Water filters from Doulton can be a small step at the domestic level. It not only saves water while filtering but also ensures that the cost is kept minimal and quality paramount.
