These climate oscillations will have been   expressed differently in various parts of the globe, depending on distance   from the equator, ocean position and currents, continental mass and mountain   ranges. Thus in the last ice age the massive Laurentide ice sheet covered   much of the North America as far south as 40°N, including the Great Lakes,   while the Scandinavian ice sheet only reached 52"N covering parts of Britain   and northern Europe. The west coast of North America was not so affected by   ice and neither was northern Russia as compared with their highly glaciated   neighbouring regions. In the southern hemisphere Australia and South America   were not subject to extensive glaciation, but their climates clearly were   considerably modified

这些气候振荡在全球不同地区的表现有所不同，这取决于距赤道的距离、海洋位置和洋流、大陆块和山脉。因此，在上一个冰河时代，巨大的劳伦泰冰原覆盖了北美洲的大部分地区，南至40°N，包括五大湖，而斯堪的纳维亚冰盖仅到52°N，覆盖了英国和北欧部分地区。北美洲西海岸没有受到冰盖的影响，俄罗斯北部与邻近地区相比，也没有受到其高度影响。在南半球，澳大利亚和南美洲没有遭受广泛的冰川作用，但是它们的气候明显地被改变了。
