Climate change enhances eutrophication effects, makes the seas more acidic and changes the habitats. In recent years climate change has become one of the most significant threats to the Baltic Sea. Read the latest research, comments and analyses on how climate change is affecting the Baltic Sea.

Baltic Breakfast: Impacts of climate change on the Baltic Sea – the known and the uncertain
2021.12.20: The temperature of air and water in the Baltic Sea region has already increased due to global warming, and it will continue to do so. On this, researchers and their models are certain. But when it comes to factors like precipitation and salinity, the uncertainties in the projections are larger. At the latest Baltic Breakfast, Markus Meier and Anna Rutgersson – two of the scientists in the joint HELCOM/Baltic Earth Expert Network on Climate Change – presented the latest scientific knowledge on the topic.
Comment: EU Soil Strategy treads carefully
2021.12.09: Now it is here – the long-awaited proposal for an EU soil strategy. It treads carefully though, since the Commission’s last trial in 2006 to get a soil directive in place failed. So, this proposal mainly suggests long term objectives for soils and only has few hard core legally binding actions.
New study: Climate change can impair the sea's ability to bind contaminants
2021.10.11: Climate change will probably mean increased precipitation and more rainfall. This, in turn, may may lead to a deterioration in the Baltic Sea's ability to bind contaminant such as PCBs and PAHs, according to a new study. The biggest change is likely to take place in the coastal zone.
Comment: Too vague recommendations from Baltic Sea parliamentarians
2021.09.03: The resolution on climate change and biodiversity from the Baltic Sea Parliamentarian Conference holds good ambitions, but lacks the level of concretion required to make real change.
Baltic Breakfast: Blue carbon and methane emissions – how coasts and climate are connected
2021.08.31: The coastal ecosystems in the Baltic Sea are important for the climate – both by taking up carbon dioxide from the atmosphere and by emitting methane. But are the Baltic Sea coasts net sinks or sources of carbon? At a recent Baltic Breakfast webinar, Camilla Gustafsson and Florian Roth presented their research and launched a new policy brief on the topic.
Baltic Breakfast: Seafood consumption from a sustainability perspective
2021.07.20: Is it sustainable to increase seafood consumption and how could consumers be encouraged to make sustainable choices? These issues were in focus during the last Baltic Breakfast webinar where researchers Sara Hornborg and Malin Jonell participated.
Does protecting the seas save the climate?
2021.04.01: Bottom trawling not only has consequences for fish and organisms living on the seabed, but can also affect the circulation of substances in the sea and, by extension, the climate. A large international study has estimated how much carbon that is stored on the bottoms and risks being released when they are trawled. But researchers at the Baltic Sea Centre mean that the calculations are uncertain.
Comment: Poor conditions for algae cultivation in the Baltic Sea
2021.01.28: Algae is described in a new EU initiative as a largely untapped resource that can be used to produce food as well as pharmaceuticals and biofuels, with a limited carbon and environmental footprint. However, in the Baltic Sea the opportunities are small for developing profitable algae farms in the near future.
Comment: A Blue Year for the Baltic
2021.01.22: 2020 – was it only bad? The pandemic tended to overshadow everything else, but let us forget about the terrible corona virus for a minute and consider if 2020 brought any positive news for the Baltic Sea and what we can expect of 2021.

The great plankton change – good or bad for the Baltic Sea ecosystem?
2020.11.16: The phytoplankton community of the Baltic Sea is changing. A trend towards more cyanobacteria and fewer diatoms affects the entire marine ecosystem. The big question for the marine scientists is: How?
Analysis: Baltic Sea fishing has not gone according to (multiannual) plan
2020.10.07: The decline in Baltic Sea cod and herring cannot be blamed solely on old sins. It must also be seen as a signal that something is not right in the administration, writes the Baltic Sea Center's Henrik Hamrén.

Analysis: Proposal for EU countries to have greater autonomy with agriculture
2017.12.19: The EU Commission wants to scrap greening from the Common Agricultural Policy (CAP) and create greater autonomy amongst the member states. “Increasing participation of the individual countries is good, but this presumes that the rules are the same for all; Nor must environmental considerations be undermined”, writes Gun Rudquist.
