Since 1850 there has been a mean rise in global temperature of approximately 1 0 С (1.8° F), but this rise could just be part of a natural fluctuation. Such fluctuations have been recorded for tens of thousands of years. The potential consequences of global warming are so great that many of the world's top scientists have urged immediate action, and have called for international cooperation on the problem.
