Climate change is altering marine ecosystems in numerous ways, making long-term impacts quite unpredictable. Not only are ocean temperatures rising, but there are changes in nutrient supplies, water chemistry, marine food chains, wind patterns, sea currents, and extreme weather events such as cyclones. In turn, these changes affect marine plants and animals. Environmental changes alter the abundance, distributions, breeding cycles and movements of marine life – including species that billions of people depend on for sustenance and income.
