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.

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 apolitical and policy-neutral. We are financially independent; our funding comes from small donations.
