WebThe Younger Dryas The Younger Dryas is one of the most well-known examples of abrupt change. About 14,500 years ago, Earth’s climate began to shift from a cold glacial world to a warmer interglacial state. Partway through this transition, temperatures in the Northern Hemisphere suddenly returned to near-glacial conditions. WebR. Alley, P. Mayewski, T. Sowers, M. Stuiver, K. Taylor, P. Clark. Environmental Science, Geography. 1997. The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago. This Holocene event affected….
