Thirteen of the ports with the highest supertanker traffic will be seriously damaged by just 1 metre of sea level rise, the analysis found. The researchers said two low-lying ports in Saudi Arabia – Ras Tanura and Yanbu – were particularly vulnerable. Both are operated by Aramco, the Saudi state oil firm, and 98% of the country’s oil exports leave via these ports.
The oil ports of Houston and Galveston in the US, the world’s biggest oil producer, are also on the list, as are ports in the United Arab Emirates, China, Singapore and the Netherlands.
The latest science published by the International Cryosphere Climate Initiative (ICCI) shows 1 metre of sea level rise is now inevitable within a century or so and could come as early as 2070 if ice sheets collapse and emissions are not curbed. An even more catastrophic rise of 3 metres is probably inevitable in the next millennium or two and could arrive as soon as the early 2100s.
Pam Pearson, the ICCI director, said: “It’s ironic these oil tanker ports are below 1 metre of sea level rise and need to have their eyes on these potentially higher rates of sea level rise, which themselves come from continued fossil fuel use.”
Sea level rise is the most profound long-term impact of the climate crisis, redrawing the map of the world and affecting many major cities from New York to Shanghai. But Pearson said government and corporate short-term interests meant it was being overlooked. “Basic information [from scientific assessments of sea level rise] don’t seem to have gotten into the consciousness of governments,” she said.
Aramco declined to comment.
