A report released by the interagency Untied States Global Change Research Program on 16 June 2009 summarizes the impacts of climate change on natural and human systems. The report calls for mitigation of greenhouse gas emissions sooner rather than later, because, as it observes, the impacts of climate change are appearing and will worsen in the future unless emissions are curtailed. This call for action is a departure from the position of past administrations. The need for further understanding of climate impacts is identified as a top priority. While the value of ecosystem observations and research are highlighted, the report fails to recommend expanded ecological monitoring.
