Understanding global warming using long-term glacier retreat records

该项目将确定气候对未来全球变暖的敏感性，有助于理解当今人类面临的最大问题之一。我们将采取历史性的方法，确定地球近代史上最大的全球变暖的影响后，最后一个冰河时代20,000年前。通过在关键地点建立日期明确、准确的冰川退缩记录，我们将定量估计地球变暖时的温度变化。这些发现将帮助我们了解全球变暖的未来影响，以便我们更好地为环境和经济成本做好准备。

This project will determine the sensitivity of climate to future global warming, contributing to understanding one of the greatest problems facing humanity today. We will take an historic approach, determining the effects of the greatest global warming in Earth's recent history after the last ice age 20,000 years ago. By constructing well-dated, accurate records of glacier retreat at key locations, we will quantitatively estimate temperature change as the planet warmed. These findings will help us understand the future effects of global warming so that we are better prepared for the environmental and economic costs.
