The U.S. Environmental Protection Agency released a new Climate Change Indicators Report yesterday. The report brings together data from multiple public and peer-reviewed datasets to show observed changes over time in 26 indicators of climate change – including measures of greenhouse gases, high and low temperatures, heavy rainfall, snowfall, pollen season and sea level rise.
Most of these indicators focus on the United States, but some include global trends to provide context or a basis for comparison. These indicators represent a selected set of key climate change measurements, and are not an exhaustive group of all climate change indicators. EPA's indicators are based on peer-reviewed data from various government agencies, academic institutions, and other organizations. Read more.

A new sea level rise scenarios report was released today by NOAA's Climate Program Office in collaboration with twelve contributing authors from ten different federal and academic science institutions.
The report was produced in response to a request from the U.S. National Climate Assessment Development and Advisory Committee. It provides a synthesis of the scientific literature on global sea level rise, and a set of four scenarios of future global sea level rise. The report includes input from national experts in climate science, physical coastal processes, and coastal management. Read more.
The meeting focused on scientific results from the fifth phase of CMIP (CMIP5), laboratory and scientific logistics involved with the CMIP5 undertaking, and applied use and utility of the data in the context of the water cycle and agriculture.
In attendance were members of the IGIM, who represent a broad cross section of federal agency programs; USGCRP staff and associated parties; climate and Earth system modeling laboratory staff; and federal and academic researchers. Presentations given at the meeting are available below:
U.S. Forest Service research indicates that climate change will affect habitat suitability for maple trees, threatening the multimillion dollar maple syrup industry. Changes in climate have already had an impact on the iconic sugar maple trees of the Northeastern U.S.
Climate stressors may decrease the availability of maple syrup or shift production northward by the end of the next century because of direct changes in temperature, decreases in snowpack or increases in weather disturbances such as ice storms.
“Climate change will produce winners and losers geographically. Folks who retrieve sap from maple trees in the far Northeastern region will get a longer sap flow season while those in the Southeastern regions will see a reduction,” said Dave Cleaves, Climate Change Advisor for the Forest Service.

Multiple USGS field crews from several states are recording high-water marks, collecting discharge measurements and obtaining water quality data in coastal and inland Alabama, Mississippi, and Louisiana. This information is important because it is used by the National Weather Service to issue flood warnings, and the data is also used by emergency responders and planners to mitigate current and future flood hazards. These crews are being augmented by USGS staff from the Georgia Water Science Center. As the storm continues to move, crews from Illinois, Indiana, Kentucky, Missouri and Arkansas remain ready to address flooding along the stormâ€™s track.
USGS field crews have also begun retrieving the 170 storm surge sensors and 17 temporary real-time gages that were deployed in response to Hurricane Isaac in locations where the storm has passed. Data from these sensors networks will be uploaded to the USGS Hurricane Storm Tide Sensor Map. The sensors provide critical data for more accurate modeling and prediction capabilities and allows for improved structure designs and response for public safety. Read more
