This report examines how ocean warming, acidification and more frequent extreme weather events are affecting the Great Barrier Reef’s health and the risks to its unique ecosystems in an increasingly warming climate. The report argues urgent action worldwide to reduce greenhouse gas emissions and limit the increase of global warming is essential to keep open...

This report covers the first assessment of a recent coral bleaching event at Tongareva, the largest and most remote atoll in the Cook Islands, in January 2019 and explores what can be done to mitigate the risks of climate change for there.

The update was produced in response to World Heritage Committee Decision 41 COM7 (Krakow/UNESCO, 2017) to make available the most current knowledge regarding the impacts of climate change on World Heritage properties.

This report shows how the Great Barrier Reef could be hit with repeat coral bleaching events every two years by 2034, under current greenhouse gas pollution rates.

This analysis showed that World Heritage properties containing coral reefs have been increasingly exposed to heat stress during recent years. Nearly half (13) of the 29 World Heritage Listed reef properties were exposed to levels of heat stress that cause coral bleaching, on average, more than twice per decade during the 1985- 2013 period.
