A regular commenter to Sifting Reality offered the chart below to show how undeniable global warming is. Apparently they are taken in by what looks to be catastrophic rising temperatures.
That they failed to notice the increase over the past 130 years is only about 1 degree Fahrenheit is a little amusing (sad if they did notice). However, if you look closely, the chart shows an actual downward trend beginning from about 1997. And they wonder why we call them alarmists.
