New Research Reveals Southern Ocean Absorbing More Carbon Than Previously Estimated
SYDNEY, October 26, 2023 – According to a study published today in the journal Nature, the Southern Ocean has been found to absorb significantly higher levels of atmospheric carbon dioxide than earlier models suggested. The findings, released by an international team of climate scientists from nine countries, indicate that this vast water body encircling Antarctica accounts for an increased share of global carbon sequestration, with a 20 percent rise in uptake rates over the past decade compared to prior forecasts. The research, which utilized data from autonomous floats and satellite observations collected between 2010 and 2023, identified that enhanced wind-driven upwelling and biological processes in the region are driving this shift. Dr. Elizabeth Chen, lead author from the University of Tasmania, stated, "This discovery revises our understanding of the Southern Ocean's role in the climate system, potentially impacting future policy decisions on emission targets." The study further warns that continued ocean warming could eventually compromise this absorption capacity, underscoring the need for robust monitoring. The findings have prompted new debates among global policymakers, with the United Nations Climate Secretariat calling for an urgent review of current carbon budget models.
