项目摘要

The tropics are the heat engine of the planet and home to about 40% of the world's population. However, we know very little about how and why tropical climate has changed through time. This project will develop a temperature record in the Rwenzori Mountains of Uganda covering the last ice age to the present to improve the understanding of the mechanisms that cause tropical climate change and the role of the tropics in the global climate system. The Rwenzori Mountains are among the very few glaciated tropical areas where such long-term, objective data can be obtained. This project will utilize two different sources of climate information including: 1) surface exposure dating of glacial moraines (ridges that mark former glacial extents) and glacial modeling, and 2) chemical analyses of lake sediment cores. The project will entail fieldwork in Uganda to collect glacial moraine samples and lake sediment cores. It will evaluate how tropical African temperature changes relate to similar reconstructions in tropical South America, and how they correspond to changes in solar radiation, Greenland and Antarctic ice sheet extents, and atmospheric greenhouse gas concentrations. The project will advance the effort to learn how the global climate worked over the last approximately 20,000 years.This award is cofunded by the Paleo Perspectives on Climate Change Program and the Office of International Science and Engineering.
热带地区是地球的加热引擎,占世界人口约40%的所在地。 但是,我们对热带气候如何以及为什么随着时间的流逝发生变化知之甚少。 该项目将在乌干达的卢旺达山脉(Rwenzori Mountains)建立温度记录,涵盖了最后的冰河时代,以提高对引起热带气候变化的机制的理解以及热带地区在全球气候系统中的作用。 Rwenzori山是很少能获得这种长期客观数据的冰川热带地区之一。该项目将利用两种不同的气候信息来源,包括:1)冰川冰川的表面暴露日期(标志着以前的冰川范围)和冰川建模,以及2)对湖泊沉积物核心的化学分析。 该项目将需要在乌干达进行实地调查,以收集冰河样品和湖泊沉积物核心。它将评估热带非洲温度的变化如何与热带南美的类似重建有关,以及它们如何与太阳辐射,格陵兰岛和南极冰盖的变化以及大气温室气体浓度相对应。 该项目将促进学习全球气候在过去的大约20,000年中的运作方式。该奖项是对气候变化计划和国际科学与工程办公室的古奖。
