Climate and environment Climate and environmental changes have gained an ever greater place in society and are probably our generation’s biggest challenge. We work to increase knowledge about this, and prepare forecasts for changes in the marine environment and climate, with particular emphasis on the North Atlantic and the Arctic. Global climateThe global climate is changing. Understanding which changes have taken place, which changes are ongoing, and likely changes in the future, is of great importance for how we should relate to the planet's biological diversity and for humanity. Local and regional climateClimate change is global, but the results will vary greatly from place to place and through different seasons. Some areas get increased warming in winter, others in summer. Some places will be wetter, others drier, and most areas will be exposed to more extreme weather. Extreme weather situationsClimate change will primarily manifest itself in the form of several extreme weather situations, such as heat waves and droughts, torrential rains and landslides, and floods. Extreme weather has significant costs for both nature and society. Climate effects and adaptationsClimate change will affect us all. The change will be of a direct nature if there is an increase in extreme weather events, or indirectly if extreme weather in an area can affect supply chains, food prices or refugee flows. All parts of society will be affected. Air-sea interactionsEvery second, large amounts of heat, moisture, gases, and energy pass the interface between the ocean and the atmosphere. This creates waves and ocean currents, turbulence and wind systems, low pressure and high pressure. Exchange between air and sea are also important factors that affect the climate on earth.
