The Past is the Key to the Future How will West Antarctica Ice sheet respond to the current climatic warming?
The West Antarctica Ice Sheet (WAIS) is warming and is predicted to continue for decades to come (IPCC, 2007). How will WAIS respond to this warming? To answer this question we need to know how it responded to climate changes in the geological past. One of the best places to find this is in the Ross...
