The rate of temperature increase on the surface of the Earth over the last fifty years is 0.10 - 0.16 degrees centigrade per decade. Satellite observations since 1979 in the troposphere (0 - 18 miles up in the air) demonstrate a warming trend, but vary in magnitude depending on the data used and in some cases the trend is smaller than what would be expected based on physical arguments. It is unclear to what degree the tropical tropospheric temperature trend is amplified compared to the surface trend on decadal time scales. My research explores atmospheric temperature trends.

stephen po-chedley is a graduate student at the university of washington studying climate change


I went to Union College where I received a B.S. in Physics with minors in Environmental Science and Mathematics. I’m now at the University of Washington in Seattle in the Fu Research group (Department of Atmospheric Sciences). The group focuses on radiative transfer, remote sensing, and climate change. In my fifth year, I am now supported as an IGERT Ocean Change Trainee. It is my hope that I can apply our physical understanding of climate change in a way that is meaningful to people and development efforts.


I am proudly from Buffalo, New York. I miss the autumn weather of western New York, but the Cascade and Olympic Mountains of Washington are a reasonable trade. Outside of climate science, I am also very interested in public health and have spent time volunteering for Engeye Health both in the US and in Uganda. I also spent 2013 - 2014 working with Partners in Health/Abwenzi Pa Za Umoyo in Malawi as a Medical Informatics Advisor. I have really enjoyed employing the technical and analytical skills I have learned in climate science toward understanding and improving global health concerns.
