One of the most significant features of global warming is that its changes will no longer take decades to appear, they are instant. Over the past many years, Pakistan has witnessed rather perturbing changes with regard to global warming in the form of extreme climate change, natural disasters and environmental degradation. To make matters worse, the WWF-Pakistan has reported coral bleaching in some areas of Churna Island, calling it a grave threat to the coastal biodiversity of Pakistan. When subjected to warm water, corals will expel the algae living in their tissues causing them to turn completely white, hence the term bleaching. While this may be a first for Pakistan, the phenomenon has been occurring in different parts of the world since 2014.
