🗞️ Driving the news: A study by the Alfred Wegener Institute (AWI) shows that climate change could cause the Arctic jellyfish to expand their habitat northward
• Seven of eight studied species might thrive in warmer waters by mid-century, with only one species seeing a habitat reduction, resulting in an exponential rise of the jellyfish population

🔭 The context: Jellyfish are often overlooked in ecological studies despite their important role in the marine ecosystem
• The AWI research utilized computer models to simulate rising temperatures and sea ice retreat to fill this knowledge gap

🌍 Why it matters for the planet: Jellyfish expansion would disrupt the marine food web, impacting fish populations and the overall marine biodiversity
• Overfishing and nutrient contamination could exacerbate this shift, leading to what some researchers call "ocean jellification”

⏭️ What's next: The potential dominance of jellyfish in oceans could hinder fish population recovery, and cause disruptions to fish supply globally
• Monitoring jellyfish trends is crucial for future marine resource management

💬 One quote: “The projected expansion of the jellyfish habitats could have tremendous, cascading impacts on the entire food web” (Dmitrii Pantiukhin, AWI)

📈 One stat: The lion's mane jellyfish could nearly triple the size of its current habitat as oceans warm
