The Little Ice Age is the most dramatic climate event in the SD Holocene glaciochemical record. [103] The Siple Dome ice core also contained its highest rate of melt layers (up to 8%) between 1550 and 1700, most likely because of warm summers. [104]
7 mar 2022 · Researchers have offered a range of explanations for the Little Ice Age, from volcanic eruptions to the European destruction of indigenous societies in the Americas, which caused forests to...
The Mini-Ice Age roughly spanned the era from 1200 to 1850, when countries in the Northern Hemisphere particularly experienced exceptionally cold winters. The River Thames often froze, from 1607 to 1814 there were frost fairs, and in the winter of 1780 New York Harbour froze, allowing people to walk from Manhattan to Staten Island.
When most people think of ice ages, or “glacial ages,” they often envision cavemen, woolly mammoths, and vast plains of ice—such as those that occurred during the Pleistocene (about 2.6 million to 11,700 years ago) or the late Carboniferous and early Permian periods (about 300 million years ago).
Little Ice Age (LIA), climate interval that occurred from the early 14th century through the mid-19th century, when mountain glaciers expanded at several locations, including the European Alps, New Zealand, Alaska, and the southern Andes, and mean annual temperatures across the Northern Hemisphere.
The Little Ice Age was a period of wide-spread cooling that lasted from the end of the Medieval Warm Period early in the 14th century, until the present-day warming trend that started in the middle to late 19th century (graph below).
From AD 1000 to 1700 there is a general downward trend in ΔT from approximately 0 to −0.6 K. This cooling is not steady, but appears to proceed through a number of almost step-wise decreases, discussed further below.
