Warming seas, sea-level rise affect UK coasts and seas

The Marine Climate Change Impacts Partnership (MCCIP) published the 'Report Card 2020'. In this report, it summarises the latest evidence from 26 topics regarding the physical, ecological, and social and economic impacts of climate change on UK coasts and seas. New topics for this year include oxygen, cultural heritage, and transport and infrastructure. According to the report, there is clear evidence that warming seas, reduced oxygen, ocean acidification and sea-level rise are already affecting UK coasts and seas. As a matter of fact, these changes are affecting food webs, with effects seen in seabed-dwelling species, as well as plankton, fish, birds and mammals. What is more, the upper range for the latest UK sea-level rise projections is higher than previous estimates, implying increased coastal-flood risk. The possibility of compound effects from tidal flooding and extreme rainfall is increasing, which can greatly exacerbate flood impacts. In addition, oxygen concentrations in UK seas are expected to fall more than the global average, especially in the North Sea, whike fisheries productivity in some UK waters has been negatively impacted by ocean warming and historical overexploitation. Impacts of climate change have already been observed at a range of heritage sites. Coastal assets will be ...
