To understand our world's changing climate, it is imperative that we understand how climates of the past varied. This collection brings together a series of papers published at Scientific Data that describe and share valuable data on past climates, i.e. 'paleoclimate data'.
The data were obtained from a variety of sources, including historical records that can inform us about the recent past, and biological or fossil proxies that allow us to learn about climates that existed long before man walked the Earth. They have been organized below into two sections according to the level of data processing. Learn more about these levels by reading the Comment by Harry Dowsett, 'Speaking to the past'.
