What’s Causing the Panama Canal Logjam
However, the biggest issue with the logjam concerns energy, with petroleum products being the primary commodities shipped through the canal. As Akron University’s Andrew Thomas told Al Jazeera, “Since the U.S. shale energy revolution with fracking, [the canal] has become the main way energy is moved from the east coast of the United States to China, India, Korea and Japan.” Many companies, such as the Houston-based natural gas company Cheniere Energy, are choosing to forgo the wait and instead sail around Cape Horn, which can add days to a ship’s travel time. Other container ships are using the Panama Canal Railway to move their cargo from the Pacific side to the Atlantic side, where it is reloaded back onto the ships to continue the voyage. The delays have already increased shipping costs and stoked concerns of rising inflation.
The situation is drawing comparisons to the crisis in Egypt’s Suez Canal in 2021, when a massive container ship ran aground for six days, blocking more than three hundred ships and preventing nearly $10 billion worth of cargo from moving through the canal each day.
What’s the role of climate change?
The impasse highlights the consequences of climate change on global trade and shipping as droughts and other climate disruptions are increasingly challenging crucial supply chains around the world.
Panama is one of the world’s wettest countries; the 75 inches (191 centimeters) of rainfall it receives per year provides plenty of freshwater for Gatún Lake and the canal. But meteorologists say the return of El Niño, a weather pattern characterized by unusually warm ocean temperatures in the Pacific, is making the country drier and hotter. (El Niño occurs every two to seven years on average, though it has become more frequent.) Total rainfall in Panama this year is already at historic lows, experts say, and they warn of even drier conditions next year.
This type of drought, and the resulting shipping restrictions, has happened before. But experts say this year’s situation is especially concerning because it is indicative of a larger climate shift; while drought cycles historically occur once every five years, they are now happening “once every three years,” Canal Administrator Ricaurte Vásquez Morales said.
What could be done?
Canal authorities opened an additional traffic lane in 2016 to accommodate an increasing volume of larger ships that could carry significantly more cargo. However, the additional traffic placed more pressure on the canal’s watershed, and experts say another expansion wouldn’t address today’s water problems. If drought conditions persist, officials could further reduce the number of daily transits beginning in October, threatening to interrupt shipping schedules as the holiday season approaches.
The ACP is also reportedly looking to accelerate a contract with the U.S. Army Corps of Engineers, who built the original canal, to divert four other rivers into the watershed over the next ten years. Other options include constructing a dam on the Indio River to the west of the canal, Vásquez says, or extracting water from Bayano Lake, Panama’s second-largest lake. Regardless, the economic costs are mounting; current shipping restrictions are likely to result in a $200 million drop in revenue next year.
