We are climate scientists committed to making the essentials of climate science accessible to a broad audience. We strive to build trust and partnership between our scientific community and the larger public we serve.

We share a common right to hear the evidence.


Our team travels to communities across the United States, giving the public an opportunity to meet and put their questions to climate scientists face-to-face.


Aaron Match

NSF Postdoctoral Research Fellow

New York University

Aaron Match is a National Science Foundation postdoctoral research fellow at New York University. Aaron received his Ph.D. in Atmospheric and Oceanic Sciences at Princeton University. Aaron researches the processes that lead to the observed winds and chemical distributions in Earth’s stratosphere, which is the layer of the atmosphere that contains the protective ozone layer. Aaron earned a B.Sc. in Atmospheric Science at Cornell University.

Andrew Williams

Postdoctoral Research Fellow

Princeton University & NOAA Geophysical Fluid Dynamics Laboratory

Andrew Williams is a postdoctoral research fellow at Princeton University. He studies the physics of clouds and radiation, with a focus on how they shape atmospheric circulations and the water cycle. Previously, Andrew earned a DPhil (PhD) in Climate Physics and a Masters in Physics from the University of Oxford.


Emma Ignaszewski

Communications Strategist

Emma Ignaszewski supports Climate Up Close by crafting accessible communications tools that maintain scientific integrity. In the professional sphere, Emma works at the Good Food Institute, accelerating the alternative protein industry to progress towards a sustainable, healthy, and just food system. She has a background in TEDx organizing, served as an AmeriCorps volunteer in Central New York, and earned a B.A. in English from Cornell University.



Nadir Jeevanjee

Research Physical Scientist

NOAA Geophysical Fluid Dynamics Laboratory

Nadir Jeevanjee studies the physics of clouds, radiation, and climate. He is a Research Physical Scientist at NOAA’s Geophysical Fluid Dynamics Laboratory in Princeton, NJ. He was previously the Harry Hess Post-Doctoral Fellow in the Geosciences Department of Princeton University and affiliated with the Princeton Department of Atmospheric & Oceanic Sciences. He holds a Ph.D. in Physics from UC Berkeley.


Katie Latimer

Graduate Student

UC Berkeley

Katie Latimer is a graduate student at UC Berkeley, where she has studied (at various points) physics, chemistry, and climate science. She also holds a Master of Science degree from the Perimeter Institute of Theoretical Physics in Waterloo, Ontario. Relevant past research topics include computational materials science oriented towards discovery of materials well-suited to battery and energy storage technology, as well as the impact of aerosol pollution on the intensity of storms in Earth's atmosphere.


A select few should not hold the keys to climate science. We all share a common right to hear the scientific evidence and reach our own independent judgments. But on climate change, the American public is rarely presented with a fair hearing of the facts.


Instead, the national conversation too often revolves around the opinions of politicians, not the people.

Our principles are rooted in transparency, opportunity & inquiry.

Climate Up Close was founded by climate scientists to ensure that the doors of opportunity remain open, and that all can participate in the scientific inquiry into our climate.

Climate Up Close is nonpartisan and policy-neutral. We are financially independent; our funding comes from small donations.
