ClimateWatch Science Advisor
As a result of climate change, warm tropical ocean currents are expected to strengthen and persist for longer periods in southern coastal area normally dominated by cooler waters. The consequent increases in water temperature are likely to result in unfavourable growing conditions for cool water algae species, causing a loss of seaweed in some areas.
Where To Look
