For all topics, confidence ratings are provided for what is already happening and what could happen. The confidence ratings of low, medium or high are based upon the amount of evidence available and the level of scientific consensus.
Changes in confidence since the 2010-2011 Report Card
Confidence may go up or down due to new data and model outputs becoming available or through changes in understanding of the science. The majority of confidence ratings have stayed the same since 2010-11; with nine of the confidence ratings increasing and two reducing.
Knowledge gaps and research priorities
As part of this year’s submission, authors were asked to identify key knowledge gaps within their topic area. MCCIP is publishing a Research Priorities report based upon the knowledge gaps identified in the MCCIP Report Cards and supplemented by Charting Progress 2 and Climate Change Risk Assessment (CCRA). This report will be available from the MCCIP website by March 2014
