Read here. The climate alarmist scientists have made every effort during 2009 to hype global warming and climate change scares. As the CO2 emissions scare weakened in the face of mounting evidence that human CO2 does not have a major impact on temperatures, the alarmists turned their focus on methane. As the chart below reveals though, methane levels did not "accelerate" as predicted in 2009, nor have they been on an accelerating trend for the last 8 years. In fact, methane levels will hold steady for extended periods, then will shift up for a short time (as in 2007), then return to a steady state; this growth pattern seems to have no relationship to human activities.
