Protecting Nature Essential for Climate Goals, Warns Leading Scientist at COP28
Johan Rockström, director of the Potsdam Institute for Climate Impact Research, has emphasized the critical role of protecting natural ecosystems in achieving climate goals. Speaking at COP28 in Dubai, Rockström warned that even with a fossil fuel phase-out, climate breakdown remains inevitable unless efforts are made to safeguard the natural world. He highlighted the importance of retaining carbon sinks, such as forests, wetlands, and peatlands, as integral components in limiting global temperature increases. The scientist urged a focus on preventing the destruction of natural landscapes and habitats to ensure a safe future for humanity within the 1.5°C limit.
Johan Rockström, a prominent climate scientist and director of the Potsdam Institute for Climate Impact Research, issued a stark warning at COP28, emphasizing that efforts to combat climate change must extend beyond a mere phase-out of fossil fuels. According to Rockström, human-induced destruction of nature is pushing the planet to a precarious point, and without concurrent measures to protect the natural world, achieving climate goals remains elusive.
Rockström highlighted a crucial aspect of climate models, indicating that they rely on the preservation of natural "carbon sinks" like forests, wetlands, and peatlands. These ecosystems play a pivotal role in absorbing and storing carbon dioxide, mitigating the impact of excess atmospheric carbon. The scientist stressed that the destruction of these carbon sinks would accelerate the rise in carbon dioxide levels, undermining global efforts to limit temperature increases.
Speaking from COP28 in Dubai, Rockström pointed to the Amazon rainforest as a poignant example of the urgent need for nature protection. The Amazon, facing threats from logging, rising temperatures, and regional drought, is approaching a potential tipping point. Rockström highlighted the complex dynamics involved in deforestation, which can trigger a "tipping point" leading to a transition from a forested state to a savannah-like condition.
Rockström referenced research suggesting that the Amazon could tolerate up to 3°C of heating before reaching a tipping point. However, ongoing deforestation, currently at approximately 17%, brings the ecosystem dangerously close to this threshold. The scientist cautioned that once a tipping point is crossed, irreversible changes occur, making it imperative to prevent such scenarios.
Similar environmental challenges are observed in other significant forest systems globally, including Africa's Congo basin and the forests of southeast Asia, along with the impact of bark beetles and wildfires in boreal forest ecosystems.
At COP28, where discussions on fossil fuel phase-out are ongoing, Rockström's warning underscores the interconnectedness of climate action and nature preservation. While debates persist on commitments to phase out or phase down fossil fuels, the scientist stresses the urgency of protecting natural systems simultaneously.
Razan Al Mubarak, the president of the International Union for Conservation of Nature, echoed Rockström's sentiments, emphasizing the necessity of both fossil fuel phase-out and nature preservation. The ongoing discussions at COP28 involve disagreements among governments on fossil fuel commitments, with vulnerable countries advocating for an unconditional phase-out.
Rockström concludes by calling for a decisive agreement to protect remaining intact nature, emphasizing the need to halt the destruction of ecosystems. The scientist urges a comprehensive approach that combines a phase-out of fossil fuels with robust measures to safeguard the world's natural heritage, providing the best chance to meet climate goals.

FAQs: Q1: Why does Johan Rockström emphasize the importance of protecting natural ecosystems alongside a fossil fuel phase-out? A1: Rockström highlights that a fossil fuel phase-out alone may not prevent climate breakdown, stressing the crucial role of natural "carbon sinks" like forests. Preserving these ecosystems is vital for limiting global temperature increases.
Q2: What is the example provided by Rockström to illustrate the urgency of protecting nature? A2: Rockström points to the Amazon rainforest, where a combination of threats, including deforestation, logging, and rising temperatures, is pushing the ecosystem toward a potential tipping point.
Q3: What are the ongoing discussions at COP28 related to fossil fuels? A3: Governments at COP28 are engaged in debates over commitments to either phase out or phase down fossil fuels. Vulnerable countries, including small island states, advocate for an unconditional phase-out.
Q4: What does Rockström call for in terms of protecting nature and addressing climate change? A4: Rockström urges a comprehensive agreement to protect intact nature, emphasizing the need to stop the destruction of ecosystems. He advocates for a combined approach of fossil fuel phase-out and nature preservation.
Q5: Why is the interconnectedness of climate action and nature preservation emphasized at COP28? A5: Rockström and others stress that achieving climate goals requires addressing both fossil fuel emissions and the protection of natural systems. The ongoing discussions involve finding a balance between these interconnected priorities.
