The 37th Session of the World Climate Research Programme (WCRP) Joint Scientific Committee (JSC) took place from 25 to 27 April 2016 in Geneva, Switzerland. As part of this meeting the JSC approved two new 'Grand Challenges'. These focus on climate-carbon interactions and on climate prediction on time scales from years to decades, both very important to our understanding of how Earth’s climate will change in the coming years. WCRP intends to promote these projects through community-organized workshops, conferences and strategic planning meetings as well as to advocate further for international partnership and coordination.
