Depending on which climate alarmist "expert" you listen to, be it Al Gore, Tom Steyer, Obama, John Holdren or Michael Mann, each claims that the U.S. is suffering from CO2-caused extreme climate change...big problem though, NOAA empirical measurements of precipitation (snow and rainfall) prove those claims are nothing but blatant, political anti-science lies falsehoods exaggerations.....

A prior 'C3' article documented the current normality of extreme drought across the globe.

With that said, the western U.S. is currently experiencing a very bad drought. If it's the start of another 200-year mega-drought, which plagued the area prior to the 1700's, there will be some very serious problems.

But for the entire U.S., NOAA reports that recent precipitation levels are normal - extreme high or low precipitation levels are not the norm.

The chart on the left is a plot of NOAA monthly measurements of precipitation since 1895, through June 2014. (NOAA dataset source) The black dots represent the moving 5-year (60-month) average of atmospheric CO2 levels.

The dark blue curve is the simple 60-month moving average of precipitation; the red line denotes the average monthly rainfall over the 1,434 months. As can be seen, the moving average is just about parked on top of the overall average - the declared current climate extremes purported by alarmists do not exist for the U.S. (nor for the globe as the prior article pointed out).

The total lack of precipitation extremes over the last 15+ years is completely counter to the CO2-based CAGW hypothesis that alarmists believe in fervently.

And what about other climate change "extremes" they hypothesize - well, the charts tell the real science story.

On this article's chart, the past extremes have been denoted (see color dots). Clearly, weather extremes can happen on a monthly basis, but they are rare, with no apparent association to CO2. Extended extreme precipitation levels over decades are literally non-existent in the NOAA climate record database.

Those Stubborn Facts: U.S. climate extremes of excess/minimal precipitation (rainfall and snow) are not evident in the recent climate record. The alarmist hypothesis that human CO2 causes modern precipitation extremes does not hold water, so to speak.
