Arctic Changes Threaten Global Climate Stability

A study published in Nature Climate Change reveals significant shifts in Antarctic phytoplankton communities over nearly three decades, driven by reduced sea ice and iron availability, leading to a decline in diatoms crucial for carbon sequestration. These changes threaten to disrupt the marine food web and accelerate global climate change by decreasing the ocean's ability to store carbon, highlighting the importance of long-term data collection in understanding climate impacts.
