The Influence of Anthropogenic Aerosols and Greenhouse Gases on Oceanic Heat Distribution
Introduction
The University of California, Riverside-led team has conducted a study to investigate the impact of anthropogenic aerosols and greenhouse gases (GHGs) on the storage and distribution of heat in the world’s oceans since the industrial age. The researchers utilized coupled climate model simulations to quantify and isolate the effects of both factors, revealing their distinct roles in shaping the pattern of heat uptake, redistribution, and storage in the oceans.
Key Findings
The study indicates that anthropogenic aerosols, driven by human activity, have a greater influence on altering the distribution of oceanic heat compared to the effects of globally increasing GHGs. Changes in ocean circulation and interbasin heat transport driven by anthropogenic aerosols play a significant role in modifying stored heat, particularly in the Atlantic and Indo-Pacific Oceans. These findings are crucial for developing effective climate mitigation strategies and understanding the implications of individual anthropogenic forcings on regional sea level change.
Implications for Sustainable Development Goals (SDGs)
The Sustainable Development Goals (SDGs) aim to address climate change and its impacts. This study enhances our understanding of the effects of anthropogenic aerosols and GHGs, which have been identified as key drivers of climate change. By comprehending the specific effects of these forcings on oceanic heat redistribution, strategies can be developed to mitigate climate change and achieve SDG 13: Climate Action.
Methodology
The researchers conducted several coupled climate model simulations focused on the historical period. These simulations included:
- HIST-AER: Examined the impact of human-induced aerosol changes during the historical period.
- HIST-GHG: Focused on the effects of human-induced greenhouse gas changes during the historical period.
- HIST: Encompassed all forcings, including human-induced aerosol and greenhouse gas changes, land use modifications, and volcanic eruptions during the historical period.
- piControl: Set all forcings to preindustrial levels.
Researcher Insights
Wei Liu, the lead researcher, highlighted the importance of understanding the effects of specific anthropogenic forcings on oceanic heat redistribution. This understanding will contribute to the development of strategies to mitigate climate change and achieve SDG 13: Climate Action. Shouwei Li, the first author of the study, emphasized the effectiveness of aerosol-driven changes in ocean circulation and interbasin heat transport in altering oceanic heat distribution compared to the impact of increasing greenhouse gases on this distribution.
Validation and Collaboration
The research team validated their findings by comparing their model simulations with observational data. The observed oceanic warming closely aligned with the warming patterns predicted by their model simulations. Wei Liu collaborated with researchers from the University of California, Riverside, Woods Hole Oceanographic Institution, and Pennsylvania State University in conducting this research.
Conclusion
This study enhances our understanding of the influence of anthropogenic aerosols and greenhouse gases on oceanic heat distribution. By quantifying and isolating the effects of these factors, the researchers have revealed their distinct roles in shaping the pattern of heat uptake, redistribution, and storage in the oceans. These findings are crucial for developing effective climate mitigation strategies and achieving SDG 13: Climate Action.

SDGs, Targets, and Indicators
-
SDG 13: Climate Action
- Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters
- Target 13.2: Integrate climate change measures into national policies, strategies, and planning
- Target 13.3: Improve education, awareness-raising, and human and institutional capacity on climate change mitigation, adaptation, impact reduction, and early warning
- Target 13.b: Promote mechanisms to raise capacity for effective climate change-related planning and management in least developed countries and small island developing states
The article discusses the effects of anthropogenic aerosols and greenhouse gases on the storage and distribution of heat in the world’s oceans. Understanding these effects is crucial for developing effective climate mitigation strategies (Target 13.2) and improving education and awareness on climate change (Target 13.3).

SDG 14: Life Below Water
- Target 14.3: Minimize and address the impacts of ocean acidification
- Target 14.5: By 2020, conserve at least 10 percent of coastal and marine areas
- Target 14.a: Increase scientific knowledge, develop research capacity, and transfer marine technology
The article mentions that changes in ocean circulation and interbasin heat transport driven by anthropogenic aerosols have a greater impact on altering the distribution of oceanic heat. These changes can have implications for regional sea level rise, which is a concern for coastal areas and marine ecosystems (Target 14.3 and Target 14.5).
