Inland seas may face widespread heat waves by midcentury as warming accelerates

Under the lead of the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), climate simulations were used to investigate how 19 inland seas, including the Baltic Sea, are responding to climate change. The researchers found that they have been warming faster than the global ocean since the 2000s. Projections show that marine heat waves will affect around 60% of these seas on an average annual basis as early as the middle of the 21st century. Without adherence to the Paris Agreement targets, up to 90% of these seas would be affected by heat waves. The study contributes to climate change management practices and was published in the journal Communications Earth & Environment.
