Imagine a world where global average temperatures are 4°C (7.2°F) above pre-industrial levels. Summers are extremely hot, plants struggle to survive, ocean levels are rising, and storms are larger than ever before. Turn Down The Heat: Why a 4°C Warmer World Must be Avoided, a climate report released in November 2012 by the World Bank, estimates that global average temperatures will be 4°C higher within the next century. According to the report, the current average global temperature is already 0.8°C higher than pre-industrial levels.
The World Bank’s press release recapped the report: “Turn Down The Heat: Why a 4°C Warmer World Must be Avoided summarizes a range of the direct and indirect climatic consequences under the current global path for greenhouse gas emissions.” Some of the key findings include:
- Extreme heat waves that would typically occur once every several hundred years will occur almost yearly during the summer months.
- The highest temperatures seen would range from 4° C to 10° C. Certain areas in the Mediterranean, North Africa, the Middle East, and parts of the United States could see average summer temperature increases of 6° C or more.
