What’s Going On?

The Amazon is dying. Unprecedented Droughts in 2023 and 2024

The Amazon rainforest, the world’s largest tropical rainforest and a vital carbon sink, has been reeling from back-to-back years of unprecedented drought. The dry conditions in 2023 were alarming enough, but 2024 brought an even worse crisis, pushing ecosystems, local communities, and global climate stability to the brink.

2023: A Warning Sign

In 2023, rainfall across the Amazon basin fell drastically below historical averages, with some regions experiencing a 50% drop in precipitation during the critical dry season (June–September). River levels plummeted, and the Negro River near Manaus reached a 120-year low of 12.7 meters in September. This record-setting drought stressed the biotic pump—a mechanism where forests recycle moisture through evapotranspiration to sustain rainfall—and led to widespread water shortages. Approximately 60% of the basin faced moderate to severe drought conditions, devastating aquatic ecosystems, and increasing tree mortality.

The impacts of this drought were stark:

  • Forest Stress: Reduced rainfall disrupted the Amazon's ability to absorb carbon, amplifying global warming effects.

  • Biodiversity Loss: Low water levels killed fish and aquatic species, while forest fires—exacerbated by dry conditions—ravaged wildlife habitats.

  • Economic Consequences: Local communities reliant on rivers for transportation, fishing, and agriculture saw their livelihoods dry up along with the rivers.

Despite the alarm bells ringing in 2023, the following year brought an even graver crisis.

2024: The Worst Drought on Record

By 2024, the Amazon was facing the worst drought in its recorded history. Rainfall deficits deepened, and more than 70% of the basin experienced drought conditions, with many areas in extreme drought. Rivers critical to transportation and water supply, such as the Solimões and Madeira, reached historically low levels, leaving towns and cities isolated.

The causes of the 2024 drought were multifaceted. Intensified global warming and El Niño events played a major role, driving temperatures higher and reducing moisture availability in the region. These conditions further weakened the biotic pump, which depends on a healthy forest canopy to maintain its rainfall-generating cycle.

The consequences of the 2024 drought were devastating:

  • Rainfall Deviation: Monthly rainfall in some areas was 60% below average, causing prolonged dry seasons that stretched far beyond typical patterns.

  • Carbon Emissions: The drought-affected forest released more carbon than it absorbed. With massive tree die-offs and increased forest fires, the Amazon shifted from being a carbon sink to a net emitter.

  • Local Hardship: Communities that rely on the Amazon's rivers and ecosystems for their livelihoods faced food and water insecurity on an unprecedented scale.

  • Global Implications: The Amazon's role as a climate stabilizer weakened further, contributing to a feedback loop of warming and extreme weather globally.

A Call for Action

The droughts of 2023 and 2024 are a stark reminder of the urgency to protect and restore the Amazon. These back-to-back disasters highlight the dangerous tipping point we are approaching. Scientists estimate that the Amazon stores 150-200 billion metric tons of CO2. Its collapse would release vast amounts of this carbon into the atmosphere, accelerating climate change.

To reverse this trajectory, we must:

  1. Stop Deforestation: Halting deforestation is essential to preserving the Amazon's biotic pump and its role as a global climate stabilizer.

  2. Invest in Restoration: Reforesting degraded areas can restore the Amazon’s hydrological cycle and carbon sequestration abilities.

  3. Strengthen Climate Policies: Global leaders must prioritize the Amazon in climate negotiations, recognizing its irreplaceable value to the planet.

The Amazon Is Our Lifeline

The Amazon's back-to-back droughts are not just a regional crisis—they are a global emergency. Protecting this rainforest is not optional; it is a necessity for the survival of our planet. The time to act is now, before the Amazon reaches the point of no return.
