Climate change impacts

 

Climate change is one of the most pressing environmental issues today. Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems. Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. Limiting climate change would require substantial and sustained reductions in greenhouse gas emissions which, together with adaptation, can limit climate change risks (IPCC Climate Change Synthesis report, 2014).

Current impacts of climate change in the Baltic Sea Region (BSR) are also evident and are expected to emerge also in the future.

CASCADE project developed an overview on the risk drivers and impacts of climate change in the Baltic Sea Region. CASCADE report an “Overview of climate risk
drivers, hazards and consequences” can be found here.
