## What the grant funds

The Life and Environments Through Time (LET) program supports research that advances knowledge about the patterns and processes relating to the origin and evolution of Earth’s climate, environments, life, and sedimentary record. This research takes place at the molecular, local, regional, and global scales from the Archean Eon through the Holocene epoch. LET-supported research can be useful for predicting and planning for future global change, and for the maintenance and security of ecosystem services and human societies.
