Recent evidence has revealed that the Antarctic and Greenland ice sheets are not as static as once thought. Accelerated ice loss from the Greenland Ice Sheet, disintegrating ice shelves around Antarctica, and signs that several marine-terminating glaciers in Antarctica have begun an irreversible retreat all signal that changes are taking place faster than was thought possible. Ice sheets are projected to contribute significantly to global sea-level rise, which poses dramatic risks for coastal communities and island nations worldwide. In response to these rapid changes, several USGCRP...

Since 1989, the U.S. Global Change Research Program (USGCRP) has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments
In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement. Highlights describe the state of science at the time of publication of each yearly report, and may not reflect more recent advances in understanding. The date of publication of the source report is noted on each highlight page.
The international Global Carbon Project released its annual Global Carbon Budget in September 2014, shining a spotlight on rising carbon dioxide emissions and their significance for international efforts to reduce climate change. The 2014 Budget comprises analyses of emissions data for 2013, projections through the end of 2014, and implications for future climate and energy choices. The emissions data are available to

Informal education settings such as zoos, aquariums, and parks play an essential part in conveying science to broad public audiences. USGCRP agencies work together to support initiatives that build capacity for communicating the science and impacts of climate change among interpreters in these important educational environments. For example, the National Network for Ocean and Climate Change Interpretation (NNOCCI), funded by NSF and led by the New England Aquarium (NEAQ), comprises a partnership of aquariums, zoos, parks, academic institutions, and other non-
