Higher growing season temperatures can have dramatic impacts on agricultural productivity, farm incomes, and food security. We used observational data and output from 23 global climate models to show a high probability (>90%) that growing season temperatures in the tropics and subtropics by the end of the 21st century will exceed the most extreme seasonal temperatures recorded from 1900 to 2006. In temperate regions, the hottest seasons on record will represent the future norm in many locations… 
Bambara Groundnut for Food Security in the Changing African Climate
Global food production must respond to the demands of a growing world population, and to the hazards of climate change. Higher temperatures, unpredictable rainfall and weather patterns, changes in
Climate Change Dynamics and Imperatives for Food Security in Nigeria
Decadal variability in African rainfall is projected from General Circulation Models (GCMs) to continue under elevated greenhouse gas scenarios. Effects on rain intensity, spatio-temporal variability
Analysis and Short-Term Forecast of Climatic Changes in the Adaptive Breeding of Spring Cereals
Abstract Global climate warming increased the occurrence frequency of extreme weather anomalies: heat waves, droughts, and rainstorms. The forecasted 1.5°C increase in temperature by 2050 indicates
World Food Security: The Challenges of Climate Change and Bioenergy
Over 1.02 billion people in the world suffer from hunger today. Securing world food security in light of the impact of climate change may be one of the biggest challenges we face in this century.
Delayed Seasonal Cycle and African Monsoon in a Warmer Climate
Increasing greenhouse gases will change many aspects of the Earth's climate, from its annual mean to the frequency of extremes such as heat waves and droughts. Here we report that the current
Large scale tropical deforestation drives extreme warming
Accelerating deforestation rates in Earth's tropical rainforests have dramatic impacts on local public health, agricultural productivity, and global climate change. We used satellite observations to


Prioritizing Climate Change Adaptation Needs for Food Security in 2030
Results indicate South Asia and Southern Africa as two regions that, without sufficient adaptation measures, will likely suffer negative impacts on several crops that are important to large food-insecure human populations.
Rice yields decline with higher night temperature from global warming.

This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming and a close linkage between rice grain yield and mean minimum temperature during the dry cropping season.
Impacts of Summer 2003 Heat Wave in Europe
The extreme drought and heat wave that hit Europe in the summer of 2003 had enormous adverse social, economic and environmental effects, such as the death of thousands of vulnerable elderly people,
Why are agricultural impacts of climate change so uncertain? The importance of temperature relative to precipitation
Estimates of climate change impacts are often characterized by large uncertainties that reflect ignorance of many physical, biological, and socio-economic processes, and which hamper efforts to
Genetic approaches to crop improvement: responding to environmental and population changes
Progress has been made in the isolation and functional analyses of genes controlling yield and tolerance to abiotic stresses and promising new methods are being developed for identifying additional genes and variants of interest and putting these to practical use in crop improvement.
The effect of drought and heat stress on reproductive processes in cereals.
The results achieved so far indicate that various plant organs, in a definite hierarchy and in interaction with each other, are involved in determining crop yield under stress.
