Global warming will cause widespread conflict, displace millions of people and devastate the global economy

Tom Bawden in the Independent (UK): Climate change will displace hundreds of millions of people by the end of this century, increasing the risk of violent conflict and wiping trillions of dollars off the global economy, a forthcoming UN report will warn.

The second of three publications by the UN’s Intergovernmental Panel on Climate Change, due to be made public at the end of this month, is the most comprehensive investigation into the impact of climate change ever undertaken. A draft of the final version seen by The Independent says the warming climate will place the world under enormous strain, forcing mass migration, especially in Asia, and increasing the risk of violent conflict.

Based on thousands of peer-reviewed studies and put together by hundreds of respected scientists, the report predicts that climate change will reduce median crop yields by 2 per cent per decade for the rest of the century – at a time of rapidly growing demand for food. This will in turn push up malnutrition in children by about a fifth, it predicts.

The report also forecasts that the warming climate will take its toll on human health, pushing up the number of intense heatwaves and fires and increasing the risk from food and water-borne diseases. While the impact on the UK will be relatively small, global issues such as rising food prices will pose serious problems. Britain’s health and environmental “cultural heritage” is also likely to be hurt, the report warns....
