Climate Change and Health

I understand climate change to be environmental occurrences that can be classified as, out of the ordinary or extreme. So in a climate that is usually rainy, we might experience bouts of flooding (like in the last 6 months over the northern and western UK); or dry areas, like South Africa which is classified as a semi-arid country, which is now experiencing severe water shortages and is currently in drought. Climate change makes environmental conditions more extreme than what has been usually experienced previously. It is not only an effect on climate, that we as people experience, it is also the effect on the natural world; such as the warming of the oceans killing coral reefs and marine life, the drying up of perennial lakes or the extinction of species that could not adapt fast enough to survive the quickly changing climate. Climate change is the out of the ordinary, and usually extreme, changes of the weather and the environmental conditions.
