The avertable death of world heritage sites

By Martin Wagner and Noni Austin

Climate change has claimed another victim. Almost one-quarter of the coral in Australia’s Great Barrier Reef World Heritage Area — one of the world’s richest and most complex ecosystems — has died this year, in the worst mass coral bleaching in recorded history. Even in the far northern reaches of the reef, long at a sufficient distance from human pressures like coastal development to preserve, to a large extent, coral health, a staggering 50 percent of the coral has died.

The above-average sea temperatures that triggered this bleaching were made 175 times more likely by climate change. As the ocean continues to absorb heat from the atmosphere, large-scale coral bleaching like that which has decimated the Great Barrier Reef — not to mention other destructive phenomena spurred by rising temperatures — is likely to become even more frequent and devastating.

The future of priceless World Heritage sites — and, indeed, the planet — depends on the immediate reduction of climate change-inducing greenhouse-gas emissions. Yet, many of the governments responsible for protecting these sites within their borders are not only failing to take strong climate action; they are actively pursuing dirty energy projects like coal mines and coal-fired power plants.

Even as the Great Barrier Reef dies before our eyes, Australia continues to increase its exploitation of dirty fossil fuels. In the past year, the Australian government has approved both the massive Carmichael coal mine and the Abbot Point terminal, located near the reef, to facilitate the global export of output from the Carmichael mine. The emissions attributable to the Carmichael mine will be some of the highest resulting from a single project anywhere in the world.

And the problem is not limited to Australia. In low-lying Bangladesh, one of the countries most vulnerable to climate change, the government supports a proposal to build two huge coal-fired power plants adjacent to the Sundarbans World Heritage site. India, too, supports the proposal.

Not only will these power plants emit large quantities of greenhouse gases, they will also devastate the Sundarbans, where the Ganges and other rivers meet the Bay of Bengal in a spectacular delta of mangrove islands that is home to endangered Bengal tigers and river dolphins.

The power plants will pollute the waters with toxic coal ash, bring constant coal barge traffic and require the dredging of riverbeds. Mercury from the smokestacks will accumulate in the marine life, permanently contaminating the food supply of hundreds of thousands of people and vulnerable wildlife.

It is true that Bangladesh is energy poor, a problem that must be addressed if it is to continue to develop economically. However, there are alternatives. The country has significant potential for renewable energy production and it is already a world leader in rooftop solar energy.

Of course, the responsibility to avert dangerous anthropogenic climate change does not fall only on countries that are home to World Heritage sites. However, knowing what we know today, initiating such damaging dirty energy projects is indefensible.

With governments failing to protect our natural heritage, the World Heritage Committee must step up, in order to help bring an end to the relentless exploitation of fossil fuels. Specifically, the committee should make recommendations to governments to reduce fossil fuel-related threats, identify sites that are in particular danger from such threats and carry out monitoring missions.
