Scorching heat and persistent drought continue to grip Europe, with France, Spain, Italy, Germany, Hungary, and Romania among the hardest-hit nations. Temperatures have recently soared past 40-43掳C in many areas, while the Rhine and Danube rivers have fallen to multi-decade lows. This extreme weather has evolved from a meteorological disaster into a multifaceted economic shock, impacting energy, logistics, and agriculture, and forcing several nuclear power plants to face the threat of shutdown. Concurrently, geopolitical factors are relentlessly pushing natural gas prices higher, sounding an alarm for the region's slowly recovering economy.

Liquid cooling challenges have crippled nuclear plants. On the 13th, Romania's state nuclear power company announced that the Danube River's water level had dropped to a historic low this week, causing a cooling water shortage at the country's sole nuclear facility, the Cernavod膬 Nuclear Power Plant. The only operational reactor was disconnected from the grid, leading to a complete shutdown. On the 3rd, the Romanian military blasted a section of underwater rock in the Danube to direct river flow toward the reactor. Affected by the weather, the company had already shut down one reactor on July 28th. The two reactors typically supply approximately 20% of Romania's electricity. Prime Minister Marcel Ciolacu previously announced that car manufacturers Dacia and Ford had agreed to suspend production at their Romanian factories until August 19th, voluntarily reducing electricity consumption by about 200 megawatts. The Danube River, stretching over 2,800 kilometers through more than a dozen European countries before emptying into the Black Sea, has hit its lowest level in 30 years due to consecutive heatwaves and severe drought. In neighboring Hungary, the country's only nuclear plant, the Paks Nuclear Power Plant, is also facing a cooling water shortage due to the low level of the Danube. This plant typically provides about half of Hungary's electricity needs, and its output fell to roughly 10% of its designed capacity at the beginning of the month. Rainfall this week has provided some relief, allowing the Paks plant to restart one turbine unit. Hungarian Prime Minister P茅ter Magyar stated on social media Monday that two of the plant's eight turbine units have resumed power generation. In France, where approximately 70% of electricity comes from nuclear power, the number of reactor shutdowns this summer has hit a record high due to the ongoing extreme heat, wildfires, and drought. Most nuclear plants are built near rivers or coastlines to use local water sources for cooling. European governments are now studying various solutions to mitigate the vulnerability of nuclear power to heatwaves and low water levels, such as upgrading cooling systems and scheduling maintenance to avoid peak extreme heat periods.

Economic challenges have emerged. Since the onset of the Russia-Ukraine conflict, Europe has been under the constant threat of an energy crisis. While the economy showed surprising resilience in the second quarter, the recovery's foundation is not solid. July inflation rebounded slightly, the US-Iran conflict has disrupted oil prices, and import price pressures are resurfacing. The combination of geopolitical energy shocks and extreme heat and drought has become a significant new downside risk for the third quarter, leaving the European Central Bank in a dilemma between growth and inflation. Analysis from First Financial shows that this week, both European and British natural gas futures contracts surged over 8%. The uncertain resolution of the Middle East conflict and the potential reopening of the Strait of Hormuz remain persistent supply-side concerns. Meanwhile, a fierce heatwave in Southern and Central Europe is boosting demand for electricity for cooling, which in turn increases gas-fired power generation, further diverting natural gas resources that would otherwise be injected into storage. British Prime Minister Andy Burnham convened a government emergency meeting (Cobra) on Wednesday to address the extreme heat, wildfires, and drought. This marks the second time this year the UK has held such a high-level emergency meeting due to a heatwave, as the country faces a high of 38掳C on Thursday. A research report from Triodos Bank in the Netherlands last week estimated that the economic losses from Europe's scorching heat could reach 鈧?80 billion ($207.7 billion), primarily driven by a significant drop in labor productivity. This loss is roughly equivalent to 1% of the EU's GDP, while the 27 member states are expected to grow at a rate of just around 1% this year. The report highlighted the main channels through which heat impacts the EU's GDP: falling agricultural output driving up food prices; constrained energy production and higher electricity costs; impeded transportation and rising logistics costs, with the Rhine River also facing low water levels, forcing cargo ships to sail with reduced loads, which suppresses German industrial production and could alone drag third-quarter GDP by about 0.2 percentage points; and a decrease in labor efficiency. Gareth Redmond-King, International Project Lead at the Energy and Climate Intelligence Unit, stated, "Many would say that treating this as an emergency now is already too late. The extreme heat, and the cascading secondary effects, including wildfires and river droughts, all indicate that the climate system is in crisis. This is not a passing phenomenon."
