This week’s segment discusses how climate change is becoming more threatening to natural wonders around the world. 

Transcript: Climate change now threatens one in four Natural World Heritage sites.

This is the Iowa Environmental Focus.

There are a total of 206 Natural World Heritage properties elected by UNESCO or the United Nations Educational, Scientific and Cultural Organization. The organization announced at November’s United Nations climate change summit in Bonn, Germany that sixty-two of these sites are now considered to be at risk due to climate change, up from 35 sites listed in 2014.

A variety of sites are threatened, but coral reefs and wetlands are among the most fragile ecosystems. Rising sea temperatures have killed off colorful algae that used to adorn the Belize Barrier Reef and Australia’s Great Barrier Reef. The Everglades are also threatened by climate change as sea level rise brings salt water into the wetland ecosystem.

Proper management can reduce risk for some threatened natural heritage sites. The report tells of replenished elephant and chimpanzee populations in Ivory Coast’s Comoé national park due to successful management and international support.
