Latest NASA Data Confirms That Global Warming Is Not Unequivocal, Not Irreversible, Not Accelerating, Not Significant
The IPCC and the typical CAGW alarmist claims all sorts of magical powers for CO2-induced global warming - per the data NASA / GISS data though, none are true
The above blinking chart (created here) shows four different short-term linear trends (five years ending 1998, 2003, 2007 & 2011) for NASA/GISS surface temperatures. The latest 5-year trend ending 2011 is +0.36°C per century rate.
The long-term trend (+0.60°C per century rate) since 1880 is higher than 5-yr period ending 2011.
The current 5-year trend is below the long-term trend
There have been recent prior periods when the short-term trend has been moderately negative (cooling rate)
There have been recent prior periods when the short-term trend has been highly positive (warming rate)
Atmospheric CO2 levels keep increasing across every short-term period at approximately the same per century rate
Atmospheric CO2 does not cause global temperatures to be: unequivocal, irreversible, accelerating or significantly warming on a permanent basis
Recent global warming could convert to global cooling very quickly (in a span of a few years) regardless of atmospheric CO2 levels
Robust global warming (cooling) is not "incontrovertible"
