lasteaiaharidust

Lasteaiaharidust, also known as the Last Glacial Maximum, was a period during the Pleistocene epoch when the Earth's climate was at its coldest point in the last 1.2 million years. This event occurred approximately 26,500 to 20,000 years ago, marking the peak of the last ice age. During this time, vast ice sheets covered significant portions of North America, Europe, and Asia, reaching as far south as the latitude of modern-day London and New York City.

The Last Glacial Maximum is characterized by its extreme cold temperatures, which led to the expansion of glaciers and the formation of large ice sheets. These ice sheets significantly altered global sea levels, causing them to drop by about 120 meters due to the vast amounts of water stored in the glaciers. This had profound effects on coastal regions, leading to the exposure of land that is now submerged in the present-day oceans.

The climate during the Last Glacial Maximum was not uniform globally. While the Northern Hemisphere experienced severe cold, the Southern Hemisphere, particularly Antarctica, was relatively warmer. This temperature gradient contributed to the formation of strong winds and ocean currents, which influenced global climate patterns.

The Last Glacial Maximum played a crucial role in shaping the modern landscape and climate. As the ice sheets retreated, they left behind a variety of landforms, including moraines, drumlins, and eskers. These features provide valuable insights into the dynamics of past ice movements and the subsequent changes in the Earth's surface.

The end of the Last Glacial Maximum marked the beginning of a gradual warming period, leading to the current interglacial period known as the Holocene. This transition was accompanied by significant changes in vegetation, animal populations, and human societies, reflecting the profound impact of climate change on the Earth's ecosystems and human civilizations.
