Evidence from ice cores, tree rings, stalagmites, marine and terrestrial deposits, and other proxies indicate that throughout the earth’s history, surface temperatures, glacier and sea ice extent, sea levels, and the distribution of plant species have varied over long periods. In fact, a reconstruction of ice cores taken at the Vostok Research Station in Antarctica shows that temperature has changed as much as 10 degrees Celsius over hundreds of thousands of years, causing extended ice ages and warming periods. Since 1900 average global temperature has warmed about 1.5°F leading many to question how human activities such as land use change and burning of fossil fuels may influence climate. This publication provides a basic understanding of Earth’s climate system, its atmosphere, and natural and anthropogenic factors that influence climate change and variability. With this knowledge, you will better understand climate terminology, concepts and processes discussed in literature and in the media.

Developing Extension Capacity to Address Issues Related to Climate Change and Animal Agriculture
Texas A&M AgriLife Extension Service—in conjunction with five partner Land Grant Institutions—is a part of a 5‐year project to address issues related to climate change and animal agriculture. The overall goal is to develop national Extension capacity and build partnerships that foster animal production practices that are environmentally sound, climatically compatible, and economically viable.
