If we are going to solve climate change, the knowledge about it must be open. Only 47% of research papers on climate change are open. That means less than half of all climate research can be read by the public, researchers, journalists, educators, policy makers, students and others seeking to mobilize this knowledge in mitigations and solutions for climate change. One year ago, Creative Commons and our partners — SPARC & EIFL with the guidance of the Steering Committee — launched the Open Climate Campaign to address the lack of access to climate change research. Comprising 11 goals, the Open Climate Campaign’s mission is to make the open sharing of research the norm in climate science.
