PDF A climate trend analysis of Chad [More info]
Long-term reduction in rainfall and increasing temperature threaten Chad's future food production prospects; combined with rapid population growth and zones of substantial conflict, increasing numbers of people will be at risk.
PDF A climate trend analysis of Ethiopia [More info]
Recent trends in March-June, June-September, and March-September rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in this area.
PDF A climate trend analysis of Mali [More info]
Summer rains have remained steady for the past 20 years, but are below the long-term average. Current population and agricultural trends indicate increasing yields have offset population expansion, keeping per capita cereal production steady.
PDF A Climate Trend Analysis of Niger [More info]
While summer rains have increased during the past 20 years, temperatures have increased as well, amplifying the effects of droughts. Crop yields are low but the population is growing, pointing to rising food insecurity.
PDF A climate trend analysis of Sudan [More info]
The data shown here depict drying trends in one of the world's most food insecure regions. Decreasing rainfall since 1980 accompanied increases in air temperature greater than global warming.
PDF A climate trend analysis of Uganda [More info]
Long-term reduction in rainfall and increasing temperature threaten Uganda's future food production prospects; combined with rapid population growth these factors could increase the number of people who are at risk during the next 20 years.
Acid rain and our Nation's Capital [More info]
Describes noticeable effects of acid rain on the building stones and monuments in Washington, DC.
PDF Assessing carbon stocks, carbon sequestration, and greenhouse-gas fluxes in ecosystems of the United States under present conditions and future scenarios [More info]
Congress asked us (in the Energy Independence and Security Act of 2007) to figure out how to assess the effects of carbon storage, sequestration, and greenhouse gas fluxes in our ecosystems. Here's how we plan to do that.
Benchmark glaciers [More info]
Summary of the USGS benchmark glacier program to intensively monitor climate, glacier motion, glacier mass balance, glacier geometry, and stream runoff at three glacier basins, Gulkana and Wolverine in Alaska and South Cascade in Washington.
