PDF Terrestrial essential climate variables (ECVs) at a glance [More info]
Explains 16 distinct types of scientific information that are needed to understand climate change, including the specific parameters measured, why they are needed, who measures them, and the type and amount of information that are not yet available.
PDF U.S. Department of the Interior South Central Climate Science Center [More info]
Explains the goals and strategies to be pursued by this organizational unit of the USGS along with partners and stakeholders.
PDF USGS Hydro-Climatic Data Network 2009 (HCDN?2009) [More info]
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
PDF Using observed warming to identify hazards to Mozambique maize production [More info]
Over 30 years of substantial warming, the timing of life cycle events in maize here has changed, threatening the crop yield by exposing the plant at sensitive phases in its life cycle to increased heat and drought, and lowering the weight of its grains.
PDF A westward extension of the tropical Pacific warm pool leads to March through June drying in Kenya and Ethiopia [More info]
Analysis of sea-surface temperature in the Indian Ocean shows that warming correlates with east African rainfall; the effect on atmospheric convection and precipitation over the Indian Ocean is greater than that associated with El NiƱo (ENSO).
Coastal and Marine Geology Program [More info]

Coral mortality and African dust [More info]
Report with mini-movie and photos on the hypothesis that the atmospheric transport of dust arising from the desertification in northern Africa led to algal infestation of corals, coral diseases, and the near extinction of associated sea urchins.
Deserts, geology and resources [More info]
