Tony Barnston
Barnston is Head of Forecast Operations at IRI. Prior to coming to IRI in 2000, he was an operational seasonal climate forecaster and developmental researcher in statistical prediction methodology at the Climate Prediction Center of NOAA for 17 years. He received a masters
degree in psychology in 1975, and a masters degree in atmospheric sciences in 1976, both from University of Illinois in Urbana-Champaign. He has authored atlases, reports and journal papers on climate variability and empirical prediction, based largely on ENSO and long-term trends. At IRI Barnston ensures the production of a range of IRI forecast products, including monthly forecasts of sea surface temperatures (including an ENSO outlook) and global precipitation and temperature. Two main goals are implementation of the latest prediction research achievements into the real-time forecast products, and facilitating the creation of new versions of the forecast tailored to the needs of specific users.

Adjunct Professor, Goddard Institute for Space Studies. Del Genio investigates long-term global climate change—how the terrestrial climate system will respond to increasing concentrations of greenhouse gases over the next few decades. He studies clouds and convection, one of the biggest uncertainties in climate research today. His goal is to anticipate how changes in cloud cover, height, and optical thickness, and associated changes in water vapor, will perturb the radiative balance and either enhance or mitigate the warming resulting from greenhouse gases.
