Monday, 10 February 2025 () Kelp is being negatively impacted by climate change. Warming ocean temperatures have led to shorter growing and harvesting seasons, including for sugar kelp, one of the most commonly farmed kelp species. The loss of kelp populations can significantly impact ecosystems, and potentially the growing demand for sustainably farming food, feed, fertilizer, medicine, and cosmetics. To give kelp a chance against climate change, scientists have identified kelp species with natural adaptations to cope with heat.
