Climate change may
affect food systems in several ways ranging from direct effects on crop
production, to changes in markets, food prices and supply chain infrastructure.
There has been a dramatic increase in recent years in the

from the scientific community as new and stronger evidence of climate change is
revealed.
The Earth’s climate is constantly changing as a result of
natural processes. The atmosphere has an effect like a greenhouse on the
Earth’s temperature. The energy from the sun reaching the earth is balanced by
the energy the Earth emits to space. Greenhouse gases (GHGs) trap some of the
energy the Earth releases to space. The GHGs in the atmosphere act as a
thermostat controlling the Earth’s climate....
