🗞️ Driving the news: A new study reveals that the reduction of Sulphur pollution from global shipping in 2020 caused a "termination shock," significantly accelerating global heating
• The cut in pollution has been linked to the record-high ocean surface temperatures in 2023
🔭 The context: Until 2020, shipping emissions produced particles that blocked sunlight and helped form clouds, reducing global heating
• The study estimates an additional 0.2 watts per square meter of heat trapped over the oceans, potentially doubling the warming rate since 1880
🌍 Why it matters for the planet: This sudden reduction in cooling pollution has revealed the complex role of aerosols in climate regulation, highlighting the risks and potential impacts of geoengineering
• Understanding these effects is crucial for developing effective climate mitigation strategies
⏭️ What's next: Further research using more sophisticated climate models is expected later in 2024 to refine the understanding of the temperature rise caused by the pollution cut
• Scientists stress the importance of addressing the root causes of global warming—fossil fuel emissions
💬 One quote: “We did inadvertent geoengineering for 50 or 100 years over the ocean,” said Dr. Tianle Yuan, who led the study
📈 One stat: The 2020 regulation slashed Sulphur content in fuels by 80%, reducing these cooling effects and inadvertently increasing heat trapped at the Earth's surface
