Climate Change Cripples Panama Canal. Fixing it Could Take Years

"Parched conditions have crippled a waterway that handles $270 billion a year in global trade," reports Bloomberg. "And there are no easy solutions. "The Panama Canal Authority is weighing potential fixes that include an artificial lake to pump water into the canal and cloud seeding to boost rainfall, but both options would take years to implement, if they're even feasible. "With water levels languishing at six feet (1.8 meters) below normal, the canal authority capped the number of vessels that can cross. The limits imposed late last year were the strictest since 1989... Some shippers are paying millions of dollars to jump the growing queue, while others are taking longer, costlier routes around Africa or South America. The constraints have since eased slightly due to a rainier-than-expected November, but at 24 ships a day, the maximum is still well below the pre-drought daily capacity of about 38. As the dry season takes hold, the bottleneck is poised to worsen again... The canal's travails reflect how climate change is altering global trade flows. Drought created chokepoints last year on the Mississippi River in the US and the Rhine in Europe. In the UK, rising sea levels are elevating the risk of flooding along the Thames. Melting ice is creating new shipping routes in the Arctic. Under normal circumstances, the Panama Canal handles about 3% of global maritime trade volumes and 46% of containers moving from Northeast Asia to the US East Coast... In the long term, the primary solution to chronic water shortages will be to dam up the Indio River and then drill a tunnel through a mountain to pipe fresh water 8 kilometers (5 miles) into Lake Gatun, the canal's main reservoir. The project, along with additional conservation measures, will cost about $2 billion, Erick Cordoba, the manager of the water division at the canal authority estimates. He says it will take at least six years to dam up and fill the site. The US Army Corps of Engineers is conducting a feasibility study. The Indio River reservoir would increase vessel traffic by 11 to 15 a day, enough to keep Panama's top moneymaker working at capacity while guaranteeing fresh water for Panama City... The country will need to dam even more rivers to guarantee water through the end of the century.
