revolution, humans have been changing the global climate by emitting high amounts of
greenhouse gases into the atmosphere, potentially resulting in higher global
temperatures, changed hydrological regimes, and increased climatic variability.
Climate change over the next century may have significant effects on food supply, i.e.,
