Marshall, C.H. Jr., R.A. Pielke Sr., and L.T. Steyaert, 2003. Crop freezes and land-use change in Florida. Nature, 426, 29-30. 1900-era Land Cover 1993 Land Cover Model difference in minimum temperature Model difference in duration of freeze temperatures Areas where wetlands were converted to cropland had colder minimum temperatures and longer freezing periods. Wetlands once held heat from the day, often keeping area temperatures above freezing throughout the night. Goal: Understand past, present, and future environmental consequences of land change to support better management of their effect on people, environment, economy, and resources
