[June 2012] Overall, the scientists found that the pace of warming increased dramatically starting in the 1970s, with every state showing a rise in overall temperatures over the past 40 years. This bump coincides with the time when the effect of greenhouse gases began to overwhelm the other natural and human influences on climate at the global and continental scales, the researchers said.
