Coral skeletons act as archive of desert conditions from Little Ice Age
The Sahara and Arabian deserts did not cool as much as the rest of the Northern Hemisphere during the Little Ice Age, but in fact were drier 200 years ago than they are today, according to a new study. The Little Ice Age was a cool period from around 1450 to 1850. During this time, Europe was very cool and even experienced a “year without a summer” in 1816 due to the 1815 eruption of Mount Tambora, a volcano in Indonesia. Scientists knew Europe experienced significant cooling during the Little Ice Age because of historical data but were unsure how other parts of the world were affected, such as the Sahara and Arabian deserts.
