Have you ever wondered how scientists gather data to determine whether global temperatures are warming or what climate was like during the Ice Ages?
Paleoclimate researchers conduct studies on coral cores, ice cores, tree rings, pollen, sediment from oceans and lakes, varves, pack rat middens and other products of nature in order to learn about past climates.
The links below will help you understand how scientists collect climatic data from the past, before the days of the thermometer, barometer, rain gauge and other weather instruments.
