I am a climate scientist working to better understand past and future changes in climate. To understand past changes in climate, I work with satellite records dating back to the late 1970s to measure how much the Earth's atmosphere has warmed. I also work with climate models to predict future changes in climate. While I am largely focused on the physical climate system and understanding the Earth's sensitivity to greenhouse gases, I am also interested in understanding the effects of climate change on food security and human health.
