COP28 placed a central focus on the Ocean, covering key challenges and opportunities for its role in climate change mitigation and adaptation. The international community, represented by organizations such as Mercator Ocean International, actively participated in discussions and initiatives aimed at fostering sustainable Ocean management and addressing climate change impacts on marine ecosystems.
Key agenda highlights of Karina von Schuckmann, MOi Special Envoy for COP28
|“Where is global warming in relation to the long-term temperature goal?”
– COP28 IPCC Pavilion event
Kicking-off her nearly two weeks at the conference, Dr. von Schuckmann participated in the Science for Climate Action Pavilion, which hosted side events of the World Meteorological Organization (WMO), the Intergovernmental Panel on Climate Change (IPCC), MERI Foundation and the National Center of Meteorology of the UAE (NCM). She presented in a session entitled “Where is global warming in relation to the long-term temperature goal?” on “Tracking climate change between IPCC reports”, delivered together with Dr. Matt Palmer, also a lead author of the sixth IPCC Assessment Report (AR6), she focused on the needs and solutions for monitoring climate change between IPCC report cycles.
In our changing climate, we depend on indicators tracking the state of the Earth system to assess the impact of human activities and to make well-informed decisions. IPCC reports serve as the authoritative scientific evidence for climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). These reports are used to make assessments of where we are in terms of the Paris Agreement long-term temperature goal (LTTG) and provide information relevant to the Global Stocktake (GST). However, due to their publication cycles every 5-10 years, there are gaps in information and lag behind the rapid changes occurring in the Earth system.
Addressing this gap, Dr. von Schuckmann and Dr. Palmer presented on a recent initiative, the Indicators of Global Climate Change (IGCC), an international science community effort established in 2023, that aims to provide annual updates on essential climate indicators. It ensures ongoing public awareness of crucial aspects of global warming. MOi, a project partner, lends its expertise to analyse the Earth Energy Imbalance (EEI), a key parameter for assessing the magnitude of human-induced global warming. Over the past two decades, the EEI has more than doubled. Notably, this indicator is inextricably linked to Ocean heat dynamics, as the Ocean absorbs approximately 90% of the heat generated by human activities within the Earth system.[i]

As part of the UNFCC Earth Information Day, Dr. von Schuckmann participated in a World Café plenary session. She served as an expert of the world café topic: “Global climate indicators – from the global observing system to knowledge transfer at the science-policy nexus – what can we further do?”
This World Café session served as a dialogue platform on the science-policy nexus, acting as a catalyst for broader discussions. Focused on the global monitoring of climate change, it addresses the challenges in transferring knowledge from science to policy. Specifically, this session initiated discussions on the significance of indicators and regular reporting, such as the WMO State of the Climate and IGCC.
The GCOS Global Climate Indicators cover a comprehensive set of parameters detailing the evolving climate across various facets of the Earth system. These indicators show vital information related to key domains of climate change, including temperature and energy, atmospheric composition, Ocean and water, and the cryosphere. Serving as the foundation for the annual WMO Statement of the State of the Global Climate, these indicators contribute essential insights submitted to the Conference of Parties of the UNFCCC. Moreover, the Copernicus Climate Change Service (C3S) and the Copernicus Marine Service, implemented by MOi under the European Commission, utilize these indicators for their annual European State of the Climate and the Ocean State Report.
MOi contributed to the latest WMO State of the Global Climate report 2022, and Dr. von Schuckmann was a lead author lending her expertise on the Ocean’s absorption of heat, a key element in quantifying and understanding global warming. MOi also contributed to regional WMO reports on Europe, Asia and Pacific with expertise on sea surface temperature and marine heatwaves, for example.
