Jonathan Patz, participated in the Intergovernmental Panel on Climate Change (IPCC). The second part of its Four Assessment Report series, "Impacts, Adaptation and Vulnerability" was issued April 6, 2007. Patz is a lead author of one of the report’s chapters. The international team of authors warned that human-generated warming is already making oceans more acidic and parched regions even drier. 20-30% of the world's species may disappear if the world warms another 2.7 to 4.5° F. Such warming could intensity ozone air pollution in the US and cause many diseases to increase around the globe.

SAGE Global Land Use Data Website Now Online Scientists at SAGE have developed global databases of land cover and land use. These data sets are now available from a new website. They describe the geographic patterns of the world’s croplands, grazing lands, urban areas, and natural vegetation. The website also includes other popular data such as human population density. The new website, developed by Navin Ramankutty and Seth Price, provides easy access to the land use data in both tabular format (for countries, states, etc. of the world) as well as in map form. The site allows the user to manipulate the data to suit their own specific requirements, and download them in several different formats.
SAGE River Discharge Database Website offers monthly mean river discharge data for over 3500 sites worldwide. The data sources are RivDis2.0, the United States Geological Survey, Brazilian National Department of Water and Electrical Energy, and HYDAT-Environment Canada. The period of record for each station is variable, from 3 years to greater than 100. All data is in m3/s.
SAGE Soil Carbon & Nitrogen Data Website Scientists at SAGE have initiated long-term soil sampling and monitoring of agricultural land across southcentral Wisconsin. Soil carbon, nitrogen, bulk density and other assorted data on land-use history are available via this database.
