In our changing climate, sea levels are rising and a city such as Venice, which is also sinking, is particularly susceptible to such changes.<\/p>\n<p>The weather patterns that have caused the Adriatic storm surge have been driven by a strong meridional (waving) jet stream across the northern hemisphere and this has fed a conveyor belt of low pressure systems into the central Mediterranean.<\/p>\n<p>&nbsp;<\/p>\n<h5><strong>One of the possible effects of a changing climate is that the jet stream<\/strong>\u00a0 : will be more frequently meridional and blocked weather patterns such as these will also become more frequent. If this happens, there is a greater likelihood that these events will combine with astronomical spring tides and hence increase the chance of flooding in Venice.<\/h5>\n<h4><strong>Mose project <\/strong><\/h4>\n<p>The so-called Mose project &#8211; a series of large barriers or floodgates that would be raised from the seabed to shut off the lagoon in the event of rising sea levels and winter storms &#8211; was successfully tested for the first time in 2013.<\/p>\n<p>The project has already cost billions of euros in investment. According to Italy&rsquo;s infrastructure ministry, the flood barriers will be handed over to the Venice city council at the end of 2021 following the \u00ab\u00a0final phase\u00a0\u00bb of testing.<\/p>\n<p>Italy was hit by heavy rainfall on Tuesday with further bad weather forecast in the coming days.
