California's majestic redwoods face unprecedented stress as rising temperatures disrupt their evolved photosynthetic processes. These ancient giants, perfectly adapted to cool, foggy coastal conditions, are experiencing thermal stress that impairs their ability to convert sunlight into energy. Recent scientific research reveals that when temperatures climb beyond their optimal range, these iconic trees significantly reduce photosynthesis rates, threatening their growth and long-term survival. This climate-driven phenomenon raises critical concerns about the future of North America's most towering forest ecosystems.
