Photosynthesis is fundamental to life on Earth, allowing plants and microalgae to convert sunlight and carbon dioxide into organic compounds. However, this essential process is highly vulnerable to heat. As global temperatures rise and heat waves become more frequent, declining photosynthetic efficiency threatens agricultural productivity and the large-scale cultivation of microalgae for biofuels and other valuable products.
