This dataset presents temperature and precipitation reconstruction from pollen records of the Northern Hemisphere. Most of the pollen proxy data where retrieved from the Neotoma Paleoecology Database. The dataset provides a comprehensive overview of the climate conditions in the Northern Hemisphere over the past few thousand years, allowing researchers to study the long-term trends and patterns of temperature and precipitation. The pollen records are a valuable tool for reconstructing past climate conditions, and this dataset is an essential resource for scientists studying climate change and its impacts on the environment.
