Polar Ecosystems: A Roadmap for Understanding and Preserving Biodiversity
Polar regions contain vast, undiscovered biodiversity but are both the most-threatened and least-understood areas of the world.
Introduction
Scientists from the University of East Anglia (UEA) and the British Antarctic Survey (BAS) are calling for a roadmap of polar ecosystems to fill the knowledge gap, preserve polar life, and protect our planet’s health. This study aims to map all biodiversity in polar regions, including the atmosphere, deep sea, land, and oceans.
The Importance of Action
The authors emphasize the need for concerted action to mitigate the impact of warming on polar ecosystems. This includes conservation efforts, sustainable management of habitats, and the sustainable bioprospecting of novel genes and compounds for societal gain. These actions are crucial for achieving the Sustainable Development Goals (SDGs).
Polar Ecosystems at Risk
Polar ecosystems are the most threatened due to their sensitivity to global warming. These ecosystems are being lost at a rapid pace, resulting in the loss of biodiversity and ecosystem services. The carbon cycle, which plays a vital role in climate regulation, is also affected.
Research Findings
The study, titled “Multi-omics for studying and understanding polar life,” published in Nature Communications, highlights the interconnectedness of polar environmental and ecological processes with everyday life and the planet’s health. Climate-induced changes in polar regions are already altering species distributions and ecosystem function.
Impacts on Polar Life
Global warming has led to shifts in species distribution, affecting the food chain in polar regions. Polar life, including microbes, seals, whales, and polar bears, depends on low temperatures and substantial snow and ice cover. These conditions are being impacted by global warming.
Arctic and Antarctic Impacts
The Arctic is experiencing temperature increases four times faster than elsewhere, leading to destabilization of the Arctic jet stream and increased likelihood of extreme weather events. Permafrost melting and collapsing Arctic coastlines are altering ecological interactions and releasing ancient carbon stores and potentially harmful bacteria.
In the Southern Ocean and Antarctic continent, warming has led to the loss of sea ice and glaciers. The Southern Ocean plays a crucial role in heat absorption and carbon drawdown, making it a significant natural negative feedback against climate change.
Preserving Biodiversity
The impacts of climate change on biodiversity and ecosystem functioning in both the Arctic and Antarctic serve as indicators of the consequences of global warming. Understanding the unique organisms in polar regions is essential for answering global questions and providing benefits for society.
The Role of Genomic Screening
Genomic screening can identify populations under stress and monitor invasive species, enabling early interventions. Obtaining full genome sequences for diverse organisms in polar ecosystems will revolutionize our understanding of evolution in cold environments and adaptive responses to a warming world.
Conclusion
The roadmap for polar ecosystems is crucial for achieving the SDGs and preserving biodiversity. It is essential to act now to prevent a substantial loss of knowledge regarding evolutionary adaptation to the cold. The study published in Nature Communications provides a foundation for future research and conservation efforts.
‘Multi-omics for studying and understanding polar life’ is published on 20 November 2023 in Nature Communications.
SDGs, Targets, and Indicators Analysis
1. Which SDGs are addressed or connected to the issues highlighted in the article?
- SDG 13: Climate Action
- SDG 14: Life Below Water
- SDG 15: Life on Land
The article discusses the threats to polar ecosystems due to global warming and emphasizes the need for conservation efforts and sustainable management of these unique habitats. These issues align with the goals of SDG 13, which focuses on taking urgent action to combat climate change and its impacts. Additionally, the article mentions the impact of climate change on the carbon cycle and the regulation of the climate, which relates to SDG 14 (Life Below Water) and SDG 15 (Life on Land), as these goals aim to protect and restore ecosystems in oceans and on land.
2. What specific targets under those SDGs can be identified based on the article’s content?
- SDG 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters.
- SDG 13.3: Improve education, awareness-raising, and human and institutional capacity on climate change mitigation, adaptation, impact reduction, and early warning.
- SDG 14.2: Sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts.
- SDG 15.5: Take urgent and significant action to reduce degradation of natural habitats, halt the loss of biodiversity, and protect and prevent the extinction of threatened species.
Based on the article’s content, the targets mentioned above can be identified. The need to strengthen resilience and adaptive capacity to climate-related hazards and improve education and awareness on climate change mitigation aligns with SDG 13.1 and SDG 13.3. The call for sustainable management and protection of marine and coastal ecosystems corresponds to SDG 14.2, while the urgency to take action to reduce degradation of natural habitats and prevent the extinction of threatened species relates to SDG 15.5.
3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?
- Indicator: Species distributions and shifts
- Indicator: Melting permafrost and collapsing Arctic coastlines
- Indicator: Uptake of anthropogenic heat and carbon drawdown in the Southern Ocean
- Indicator: Genomic screening for identifying populations under stress and monitoring invasive species
The article mentions several indicators that can be used to measure progress towards the identified targets. The shifts in species distributions due to global warming can serve as an indicator of the impact on biodiversity (target SDG 15.5). The melting permafrost and collapsing Arctic coastlines indicate the ecological changes caused by climate change (target SDG 15.5). The uptake of anthropogenic heat and carbon drawdown in the Southern Ocean can be measured to assess the impact of climate change on marine ecosystems (target SDG 14.2). Additionally, genomic screening for identifying populations under stress and monitoring invasive species can contribute to understanding the adaptive responses to a warming world (target SDG 13.1).
