Claim: Global warming of 2-degrees C could cause 50% more war.

 Is this Political Junk Science Why

  War has nothing to with Global warming

The Reasons for War:
There have been so many wars, and so many reasons for them a book can be written on the reasons (if there is not one). Here are some reasons war start: Power, space, resources, personal preference, insults, to defend, racism, independence, and also the good verses evil.

Power is a reason when a nation sets out to control the world. Take the Roman Empire for an example. Rome set out to conqueror the world, and they did succeed (the known world).

Looking back at World War Two we can see Hitler making his move. It was about Power,

Resources are used up and destroyed. A Famine can be another result of a war. Even the spreading of diseases. These things can cause death out side of the conflict of war.

War is about hate, greed, and other worldly (evil) things.

The study, which includes more data than prior research in this field and covers all major regions of the globe, shows the Earth’s climate plays a more influential role in human affairs than previously thought. The results were published today (Thursday, Aug. 1) in the journal Science.

The authors found similar patterns of conflict around the world that were linked to changes in climatic, such as increased drought or higher than average annual temperature. Examples include spikes in domestic violence in India and Australia; increased assaults and murders in the United States and Tanzania; ethnic violence in Europe and South Asia; land invasions in Brazil; police using force in the Netherlands; civil conflicts throughout the tropics; and even the collapse of Mayan and Chinese empires.
