Climate change and hydrology: Environmental and societal effects

The climate and hydrology of Iceland are highly variable due to natural conditions. Significant changes in these factors over the last 15 years are in harmony with the future scenarios represented and affirmed in the latest IPCC summary report, AR5. The main purpose of IMO is to contribute towards security in society by monitoring, analyzing, interpreting, informing; providing warnings and forecasts and predicting natural hazards. It is important to keep the infrastructure strong so that IMO may fulfill its role.
