Position Papers

These community position papers are intended to address current and future research and intellectual challenges that must be tackled by WCRP, and in so doing engage the next generation of scientists who will lead the WCRP over the years and decades ahead.

These position papers will be a part of the permanent record of the meeting, published after the OSC as peer-reviewed articles in a book. We thus strongly encourage conference participants to read these papers and come to the OSC prepared to discuss them at open sessions and/or directly with the authors.

More than 20 position papers have been commissioned. They will be posted as they are received.
