Analytical chemistry underlies much of the information collected about past climate. Equally importantly, analytical chemistry enables progress in understanding the mechanisms that influence climate, knowledge that will be needed to develop reliable models of future climate. This presentation will focus on how mass spectrometry is providing information essential to climate science, ranging from temperatures, sea ice extent and other data about past climate to understanding environmental processes that are important for modeling climate, such as production and behavior of aerosols and the impact of changes in carbon dioxide concentration and other climate variables on life on land and in the lakes and oceans. The presentation complements one given by the author at the 2019 Fall National Meeting, which focused on spectroscopy from microwave to X-rays.
