The US Global Change Research Program (globalchange.gov) is currently advertising for a new position at the National Coordination Office in Washington, DC.
Communications Coordinator/Web-Content Manager
Under the direction of the Deputy Director, and in close coordination with OSTP communications staff, serves as the NCO's communications coordinator:
Develops and deploys strategies for communicating USGCRP science to a broad range of audiences, including the general public;
Creates and disseminates digital, print, web-based and multimedia content about USGCRP scientific findings through various communication and education channels, including the USGCRP constellation of websites, social media outlets, professional conferences and meetings and other relevant mechanisms;
Coordinates the development of and edits USGCRP documents and communications materials; and
Serves as the NCO coordinator for the newly formed USGCRP Interagency Communication and Education Team (ICE-t), which aims to coordinate and enhance unified Federal strategies to communicate and educate about climate change science and related global change.

At NOAA's atmospheric baseline observatory in Barrow, Alaska, captured here by fisheye lens, the concentration of the greenhouse gas carbon dioxide reached 400 ppm in April 2012, the first time a monitoring sites reached the 400 mark. Carbon dioxide levels are steadily increasing in the atmosphere due to human activities, primarily the burning of fossil fuels. Image credit: NOAA
The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, reached 400 parts per million (ppm) this spring, according to NOAA measurements, the first time a monthly average measurement for the greenhouse gas attained the 400 ppm mark in a remote location.
Carbon dioxide (CO2), emitted by fossil fuel combustion and other human activities, is the most significant greenhouse gas contributing to climate change.
â€œThe northern sites in our monitoring network tell us what is coming soon to the globe as a whole,â€ said Pieter Tans, an atmospheric scientist with NOAAâ€™s Earth System Research Laboratory (ESRL) in Boulder, Colo. â€œWe will likely see global average CO2 concentrations reach 400 ppm about 2016.â€ Read moreâ€¦

The low streamflows seen throughout much of New England this April do not foreshadow a summer drought, as researchers have determined summer rainfall plays a bigger role than snowmelt runoff in determining streamflows in the summer. In a new report by the U.S. Geological Survey, scientists also looked at how streamflow during April is influenced by both winter air temperature and precipitation. They concluded that April streamflow is more sensitive to changes in temperature than to changes in winter precipitation in southern New England.
While streamflow in April is more sensitive to changes in temperature, summer streamflows are more dependent on precipitation. Understanding the sensitivity of streamflow to climatic variation is important because people and aquatic ecosystems are dependent upon water supplies, particularly in summer low-flow seasons.

Recording how climatic variations and trends impact seasonal events in plants.

As the climate has warmed, many plants are starting to grow leaves and bloom flowers earlier. A new study published in the journal, Nature, suggests that most field experiments may underestimate the degree to which the timing of leafing and flowering changes with global warming.
Understanding how plants are responding to climate change will help develop more accurate indicators of spring, forecast the onset of allergy season or the chances of western wildfires, manage wildlife and invasive plants, and help inform habitat restoration plans. In this new study, scientists evaluated the sensitivity of plants to changes in temperature using two sources: experimental plots versus historical observations from natural sites. Read moreâ€¦

A recent study by the USDA Forest Service, Oregon State University, and the U.S. Geological Survey identified trends in stream temperatures at sites like Mack Creek near the H.J. Andrews Experimental Forest in Oregon.
Recent warming of terrestrial climates combined with decreased stream flows has raised concerns about possible increases in stream temperatures in the Pacific continental United States. Loss of cold, clean water in the region has major implications for human use and for sensitive coldwater fishes, such as salmon and trout. In a joint project, the U.S. Geological Survey (USGS), U.S. Forest Serviceâ€™s Pacific Northwest Research (PNW) Station, and Oregon State University (OSU) researchers assessed the climate effects on cold water in low and high human-influenced sites using long-term stream temperature data from the USGS and the Forest Serviceâ€¦.
