![Stronger evidence for a weaker Atlantic overturning
Levke Caesar and Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research on their new paper.
The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations.

![China floods to hit US economy: climate effects through trade chains
Anders Levermann and Sven Willner from the Potsdam Institute for Climate Impact Research on their new paper.
Intensifying river floods could lead to regional production losses worldwide caused by global warming. This might not only hamper local economies around the globe – the effects might also propagate through the global network of trade and supply chains, a study now published in Nature Climate Change shows. It is the first to assess this effect for flooding on a global scale, using a newly developed dynamic economic model. It finds that economic flood damages in China, which could, without further adaption, increase by 80 percent within the next 20 years, might also affect EU and US industries. The US economy might be specifically vulnerable due to its unbalanced trade relation with China. Contrary to US president Trump’s current tariff sanctions, the study suggests that building stronger and thus more balanced trade relations might be a useful strategy to mitigate economic losses caused by intensifying weather extremes.
