Ocean Floor Mud Reveals Secrets of Past European Climate

Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe’s climate has changed over the past 3000 years.

Samples of sediment taken from the ocean floor of the North Atlantic Ocean have given researchers an unprecedented insight into the reasons why Europe’s climate has changed over the past 3000 years.

From the warmer climates of Roman times when vineyards flourished in England and Wales to the colder conditions that led to crop failure, famine and pandemics in early medieval times, Europe’s climate has varied over the past three millennia.

For the first time, researchers have been able to pinpoint why this occurs, and the answer lies far out at sea in the North Atlantic Ocean.

Scientists from Cardiff University have studied fossil remains of shell-bearing plankton and grains buried in sediments from the North Atlantic to determine what conditions were like in the ocean on timescales of 10-20 years over a 3000-year period.
