Correction to the editorial addition: Climate was mild when and where they landed.
The Medieval Warm Period (MWP), also known as the
Medieval Climate Optimum or the Medieval Climatic Anomaly,
was a time of warm climate in the North Atlantic region
that lasted from about 950 CE to about 1250 CE.
Climate proxy records show peak warmth occurred
at different times for different regions, which
indicate that the MWP was not a globally uniform event.
The MWP was followed by a regionally cooler period
in the North Atlantic and elsewhere, which is sometimes
called the Little Ice Age.
