Half of the world's population could face food shortages by the end of this century due to climate change, a new study warned Thursday.

According to researchers, there is a 90 percent probability that by 2100 the minimum temperatures in the tropics and sub-tropical regions will be higher than the maximums so far recorded in those areas.
The affect on crop-growing in those regions would be dire, according to the projections based on direct observations and data culled from 23 computer models on the planet's evolving climate patterns.
"The stresses on global food production from temperature alone are going to be huge, and that doesn't take into account water supplies stressed by the higher temperatures," said David Battisti, a University of Washington atmospheric sciences professor.
"We are taking the worst of what we've seen historically and saying that in the future it is going to be a lot worse unless there is some kind of adaptation," added Rosamond Naylor, director of Stanford University's Program on Food Security and the Environment.
