Climate Change Research: Understanding Past Climate Changes
The dynamic nature of the Earth’s climate allows scientists to use past climate changes as indicators as to what may be expected under future climate scenarios. Scientists use proxy records derived from sources such as tree rings, ice cores, and aquatic/terrestrial sediments to better understand the causes, dynamics, and impacts of past climate changes. This knowledge is used to assess the implications of present and future climate change scenarios, which help to guide adaptation strategies.
