This resource consists of an interactive table with a comprehensive list of 29 Greenhouse Gases, their molecular structures, a chart showing a time series of their atmospheric concentrations (at several sampling sites), their global warming potential (GWP) and their atmospheric lifetimes. References are given to the data sets that range from the mid-1990s to 2008.
This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.
This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.
Global Sea Level Rise Scenarios for the United States National Climate Assessment
December 6, 2012
Global sea level has been steadily rising for decades and is expected to continue. Scientists have very high confidence that global sea level will rise at least another 8 inches and as much as 6.6 feet by 2100, causing significant impacts in U.S. coastal regions. This report lays out the science and describes possible scenarios to help planners and policy leaders assess the risks.
The annual Report Card provides clear, concise scientific information on the state of the Arctic region, organized into 5 sections: Atmosphere, Sea Ice & Ocean, Marine Ecosystems, Terrestrial Ecosystems, and Hydrology & Terrestrial Cryosphere. This edition was prepared by an international team of 121 scientists from 14 different countries. Independent peer-review of the 2012 Report Card was organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.
Heat index products are issued from the medium-range forecast function of the Hydrological Prediction Center for days 3 through 7 during the period from May 1 through September 30. With the exception of day 3, these products are based on an ensemble of model and human forecasts. Graphic plots display the cities for which the heat index forecast is interpolated, as well as shaded contours indicating the probability of the daily maximum, daily minimum, and daily mean heat index reaching or exceeding a specific threshold.
