Global Cooling was all the rage in 1979 - even a 'major' talking point in Time magazine. Because of global cooling, people would die off and (confirmed by their computer modeling) there probably wouldn't be more than about 5000 people left on the planet by 2000. The decade of the 1850s is the warmest on record. Fortunately for us, they didn't have SUVs to blame it on then and the natural , 30-year cyclical course righted itself. I recently heard that 2012 was the warmest year on record. I hope they don't forget to factor in the current cold we're having all over the country when they do the 2013 calculations.
