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.
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.
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.
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.
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.
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.
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.
Article from Water Supply Paper 2375 summarizing the correlation of precipitation, temperature, and atmospheric moisture with the frequency and intensity of a drought.
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
Here we study effects of climate and groundwater on surface-water levels, the hydrological effects on wetland water chemistry, and the combined effects of climate, hydrology, and water chemistry on plant and animal communities of prairie pothole wetlands.
Monitoring soil temperature, soil moisture, air temperature, and overall thickness of the soil and sediment that is above the permafrost, therefore undergoing freeze-thaw cycles. Climate change may affect this active layer; we want to know how it does.
