Climate change causes warming up of the earth resulting in severe heat waves in some regions. Hotter days by 6 to 15°C are expected in some countries while other will suffer colder days. All the changes in temperature and environment give rise to new pests and diseases for both humans and animals. Serious crop and animal yield losses to emerging pests and diseases will lead to starving populations.

Climate change affects prediction of the future and is an indication that the past is over. It is still difficult to assess the extent and nature of such changes in the future.
