Paleoclimate - Ice age temperatures and geochemistry
Whether the last ice age was unusually chilly is more than merely historical curiosity. Such information is used to bench mark the computer models that are used to estimate future greenhouse warming. In his Perspective, Bard discusses recent efforts to use geochemical data to calculate past climate...
