The world is figuring out how to move forward in the face of the COVID-19 pandemic by finding newer ways to support economic development, animal and human well being, and ecosystem integrity. As the priority in many parts of the world is to stay home, safe and healthy, work continues to address the ongoing crisis of nature loss which also threatens long-term health and prosperity. In fact, nature, now more than ever, is sending warning signals calling for our attention.

One such warning is from the Great Barrier Reef along Australia’s northeast coast. In March 2020, the area suffered a third mass coral bleaching event in five years due to increasingly warmer temperatures recorded in February 2020.

There have also been reports that widespread bleaching in the first quarter of the year has also occurred in East Africa.

Coral reef scientists predict that bleaching events will be more frequent, more widespread and more severe. For instance, the 2017 Coral Bleaching Futures report by the United Nations Environment Programme (UNEP) predicted, “Increasingly coral bleaching would be among the greatest threats to coral reefs due to climate change.” Annual Severe Bleaching (ASB) is projected to occur within this century for 99 per cent of the world’s coral reefs. The average projected year of ASB is 2043, the report adds. Read more…
