The Climate Resilience Fund (CRF) is a left-of-center environmentalist grant making that was started in 2016. It is based in Washington, D.C. and is a project of the Windward Fund, a left-wing nonprofit managed by the Washington, D.C.-based consultancy Arabella Advisors. Arabella Advisors manages numerous left-of-center organizations and project funds.
The Climate Resilience Fund began operations in 2016 and is housed at the Windward Fund, a left-wing 501(c)(3) sponsoring organization that provides funding, administrative, financial management, and legal support to left-of-center projects. Windward Fund is a part of a network of four nonprofits managed by Arabella Advisors, a Washington, D.C.-based philanthropy consulting firm whose clients include numerous major left-wing foundations.  Climate Resilience Fund began with a seed grant from the MacArthur Foundation, a funder of left-wing causes. 
In 2017, the Doris Duke Charitable Foundation joined Climate Resilience Fund with a donation. The CRF continues to work with other foundations, large and small, as it seeks to grow its funding and its connections. It seeks to become a hub for grantmaking and other actions by its investor partners. 
CRF wishes to address the changes caused by climate change. The CRF believes that the effects of climate change are already occurring on the planet. While it does believe that reduction of greenhouse gases is a major priority, it believes that any action is too late because the effects of climate change have already been set in motion. 
The CRF works with decisionmakers of all types to create communities that are more “resilient” to what it perceives as the harmful effects of climate change. It works to ensure that healthy communities, ecosystems, and sustainable economies thrive, no matter the challenges. 
Arabella was founded by Eric Kessler, a former Clinton administration official and field director for the League of Conservation Voters. The Arabella network is a network of “dark money” organizations where donors do not have to be disclosed. The network works by using the funds themselves as a front for their work. The Windward Fund itself was established in 2015 to be the environmentalist fiscal sponsor for the Arabella network. 
The CRF’s managing director is John Nordgren.  In 2017, Nordgren was the only paid employee of the Windward Fund. Before that, Nordgren was the senior program officer for the left-wing Kresge Foundation. Nordgren worked on environmental issues for Kresge. 
According to CRF, Kresge Foundation apparently helped develop the concept for the fund. 
The CRF has an advisory board which is made up of various representatives from the organizations that either fund or support CRF’s work. It has four members. Kate Barnes is a program officer with the MacArthur Foundation. Joel Clement is a prominent left-wing “whistleblower” against the energy policies of the Trump administration and a former civil servant in the U.S. Department of Interior. Sacha Spector is the director of environment at the Doris Duke Charitable Foundation in New York City. Finally, Tom Steinbach is the fourth and final member of the advisory board and he represents San Francisco-based Tempest Advisors.
