Congo Lakes Leaking Ancient Carbon
24 Feb
Summary
- Two large Congo lakes release ancient carbon from peatlands.
- Peatlands store carbon locked away for over 3,000 years.
- This release poses a potential threat to global climate stability.
Scientists have discovered that two significant lakes in the Democratic Republic of Congo, Mai Ndombe and Tumba, are releasing carbon that has been stored for millennia in surrounding peatlands. These tropical peatlands, crucial for climate regulation, were believed to hold their carbon securely for thousands of years.
New research reveals that up to 40% of the carbon dioxide emissions from these lakes originate from ancient peat deposits, some exceeding 3,000 years old. This ancient carbon is escaping the peatland reservoir, a phenomenon that could threaten climate stability.
The Congo Basin's peatlands hold a substantial portion of the world's tropical peatland carbon. Researchers are concerned that this release could intensify due to climate change or land-use alterations, such as deforestation for agriculture.
Further investigation is required to fully understand the complex ecosystems of the Congo Basin and the implications of this ancient carbon release on global climate patterns.
