	<abstract content_type="html">Here we use lake sediment studies from Sweden to illustrate how
Holocene-aged oxygen isotope records from lakes located in different
hydrological settings, can provide information about climate change. In
particular changes in precipitation, atmospheric circulation and water
balance. We highlight the importance of understanding the present lake
hydrology, and the relationship between climate variables and the oxygen
isotopic composition of precipitation ( Î´&lt;sup&gt;18&lt;/sup&gt;O&lt;sub&gt;p&lt;/sub&gt;) and
lake waters (Î´&lt;sup&gt;18&lt;/sup&gt;O&lt;sub&gt;lakewater&lt;/sub&gt;) for interpretation of the
oxygen isotopic record from the sediments (Î´&lt;sup&gt;18&lt;/sup&gt;O). Both
precipitation reconstructions from Northern Sweden and water balance
reconstructions from South and Central Sweden show that the atmospheric
circulation changed from zonal to a more meridional airflow over the
Holocene. Superimposed on this Holocene trend are Î´&lt;sup&gt;18&lt;/sup&gt;O&lt;sub&gt;p&lt;/sub&gt;
minima resembling intervals of the negative phase of the North Atlantic
Oscillation (NAO), thus suggesting that the climate of Northern Europe is
strongly influenced by atmospheric and oceanic circulation changes over the
North Atlantic.</abstract>
