For the past two weeks, mainstream media headlines have been awash with news of sweltering temperatures ravaging Europe and parts of North America. At least one segment – the recent record-setting heatwave in the UK – was made 10 times more likely due to climate change, according to the well-regarded World Weather Attribution group.

Quite noteworthy is the declining water level of major rivers, lakes and inland seas across the globe. These water bodies are a link to power, transportation, shipping and recreational activities for millions of people.

The Colorado River drought in the US is a classic case of falling dominoes in a country’s inland water system. Albeit overuse of the Colorado River basin is among several factors leading to its decline, climate change has exacerbated the situation. As the atmosphere becomes warmer, the Rocky Mountain snowpack that feeds the river is diminishing over time. Less water flow in the Colorado River basin means the $1.4 trillion economy it drives is in perils.

Lake Mead and Lake Powell, the two largest water reservoirs in USA, are supported by the Colorado River basin and have shrunk to record lows. Their combined storage has declined from 95 percent full in 2000 to approximately 25 percent full this year.

Last year, Boulder Harbor ramp, a major marina on the western shores of Lake Mead, had to close down. At the time, the channel depth was about two and a half feet deep - too low to provide safe lake access.

The Colorado River once flowed across the U.S border into Mexico, emptying into the Sea of Cortez. With the river barely passing the border, a once thriving marine ecosystem of the region’s delta is vanishing.

Across the Atlantic, the Danube, Europe’s second largest river, has also started showing signs of decline. The Danube’s lower reaches, which straddle Romania, have seen a significant water level drop.

Romania is a major grains and sunflower exporter in EU with part of its farms depending on Danube River basin for irrigation. The government has already warned that this year it could export much less corn after drought battered harvests. Water storage have been an issue, with levels about half of the multiyear average this year.

Besides agriculture, Danube’s low water levels in Romania also put at risk the river’s transportation and the output of the power plant along the river basin.

Meanwhile, the Rhine River has also been affected by the changing climatic regime. As one of Europe’s important inland waterways, its current low water levels is disconcerting, specifically in Germany.

“The Rhine is a crucial inland waterway, on which goods are shipped to and from the industrial heartlands of southern and western Germany. Low water levels mean that river barges will have to travel with  reduced freight to limit their draft or even cease operating altogether,” Salomon Fiedler, an economist at Berenberg Bank, said in a note last week.

Recently, the water levels at Kaub, a key chokepoint for water-borne freight, stood at 71 centimeters (cm) - below the 78 cm level recommended benchmark for navigation.

Data from the Federal Institute for Hydrology in Germany shows that the water levels are likely to decline even further in coming weeks and stay below the benchmark for the foreseeable future. A normal water level at Kaub’s measuring station is usually around 200 cm.

Approximately 80 percent of Europe’s inland waterway freight transport relies on the Rhine River. It passes through major cities and ports like Cologne, Dusseldorf, Rotterdam and Basel.

In Germany, it is crucial for transporting agricultural products, coal, oil and chemicals. In the past, Germany’s manufacturing has been severely affected when the water levels on the river declined.

In the 3rd century BC, Rhodian seafarers sailing the wine-dark waters of the Mediterranean established the foundations of maritime law. Regulating everything from bills of lading to standards of passenger behavior, their guidelines were formalized in the 7th century AD under the Byzantine Empire. Constantinople’s role is fitting, for today maritime governance involves a truly byzantine world including national governments, international organizations and classification societies. Class societies occupy an unusual role in ensuring safety at sea. They’re both rule-makers and...

Besides congestion, strikes at major ports in Europe, Asia and North America have become another addition to multiple challenges facing shippers. UK is the latest country teetering on the edge of a potential port strike. This could severely affect shipping at Felixstowe and Liverpool, two of UK’s major ports. Interestingly, the port strikes have spread to countries like Germany, where they have not occurred in the last three decades. But why are port workers downing their tools at a time...

Energy majors BP and Iberdrola announced plans to form a new joint venture designed to help in the acceleration of decarbonization of transport and industrial sectors. Together, the companies intend to collaborate to develop large-scale green hydrogen production that could be used in the maritime and other industries as well as efforts to significantly expand the fast EV public charging infrastructure to support the adoption of electric vehicles.  “Creating the lower carbon energy solutions that our customers want and need...

Transnet National Ports Authority (TNPA) South Africa has issued a request for information for project ideas for the supply of renewable energy at South Africa’s main commercial ports. The ports targeted under TNPA’s renewable energy program include Port Elizabeth, Ngqura, East London, Mossel Bay, Saldanha Bay, Cape Town, Durban and Richards Bay. In issuing the call on Monday, TNPA said the RFI process would allow it to understand the renewable energy market. Specifically, the aim is to expand use of...
