Environmental challenges in the Arctic

ByMr Nikolaj Bock

• The European Environment Agency and the Arctic

• What are the main trends & issues?• Climate change• Arctic pollution• Biodiversity

• Arctic challenges• Hydrocarbons & minerals• Shipping (incl. Tourism)• Changing living conditions

• Summary of environmental challenges

Outline

- Established by European Council Regulation (1210/90)- Operational in Copenhagen, Denmark since 1994- Annual budget 2009 of approx. 40 MEuro- Approx. 180 staff members

- EEA has 32 member countries + 6 cooperating countries in the West Balkans.

- EEA is an EU institution

- EEA is dedicated to providing sound, independent information on the environment for decision makers (EC/EP/MS) and the public.

- EEA is coordinating the European Environment Information and Observation Network (EIONET) - A network of 900 experts from 38 countries across Europe in more than 300 national organisations.

Changes in deep water formation (thermohaline circulation) is influenced by sea ice and fresh water

Increased uptake of heat in the Arctic

As the ice cover decays, highly reflecting ice/snow is replaced by highly absorbing ocean, resulting in more solar heat absorption and more melting.

Changes in Arctic September ice thickness

1958-76 average ice thickness 3.02 mFrom submarine data

1993-96 average ice thickness: 1.62 mFrom submarine data

2003-07 average ice thickness: 1.43 mFrom satellite data

Climate model predictions

Based on work by: Polar Science Center, Applied Physics Laboratory, University of Washington

The area of the Greenland ice sheet where there is at least one day of surface melting in the summer increased to a new record extent in 2007

Transportation of pollutants into the Arctic

Air – the fast route Rivers, oceans & sea ice

PCB and DDT in Ringed seal

Highest PCB levels are found in maternal blood from communities that depend on traditional diets that include marine mammals.

PCB contamination in Arctic people

Effects of Climate Change in the Arctic:

Vegetation zones in the Arctic change Altered bird migration

Effects of Climate Change in the Arctic:

Altered fish migration

Arctic biodiversity

• Retreating ice• Migratory patterns• Invasive species

• Changing vegetation• Pollution• Land degradation

Changing living conditions for the Arctic population

• Fisheries• Rein deer herding• Oil/Gas exploration• Mineral exploration• Snow/ice cover• Tourism• Infrastructure (energy/transport)

External pressures

Governance in the Arctic

• UNCLOS• Fisheries• IMO• Indigenous Peoples rights

The challenges facing the Arctic:

• Climate Change (change in snow/ice cover + permafrost)• Long range pollution (air/ocean currents)• Exploitation or damage to natural resources• Overharvesting of certain key fish stocks• Mismanagement of areas of Arctic forest and unsustainable

logging practices • Pollution from mining activities and metal ore processing plants• Impacts of infrastructure developments • Operational accidents in the oil and gas sector• Land fragmentation• Loss of biodiversity• Overall quality of surface and marine waters• Pressure from increasing tourism

Thank you for your attention!
