Fear that adverse geo-physical events may negatively impact on mining operations is nothing new. Many of the world’s biggest mines are in earthquake or monsoon-prone regions. When the tsunami hit southern Asia in 2004, miners rushed to assure themselves and their investors that their operations were secure (most of them were) and their employees safe. However, there has been general resistance on the part of the industry to concede that many such “natural” events may not be so natural after all. Rather, they are  triggered by adverse climate changes, caused by increases in global greenhouse gas emissions.
