After the Holocene varm maximum in the Stone Age
glaciers began, especially in the northern hemisphere, to form and these
often reached its maximum during the Little Ice Age. There was also more
ice than normal in the North Atlantic during this time as we can see
from the map. It shows extent of spring ice during three periods. Light
brown lines show the normal sailing routes from Norway to the west. The
bar charts show both the amount of ice and the time for this at the
Islands coasts. You have to say that it has improved a lot in recent
times |
