Temperatures, Sea Levels ‘Naturally’ Rise

 30 – 40 Times Faster Than Today’s Rates

Since 1850, CO2 concentrations have risen from 285 ppm to 400 ppm.  During these ~165 years, the IPCC has concluded that surface temperatures have warmed by 0.78°C.  This is a warming rate of only 0.05°C per decade for 1850-2012 — which happens to be the same rate of warming over the 1998-2012 period.

Modern Sea Levels Only Rising 0.17 Of A Meter/Century.
IPCC AR5 (2013):     “[T]he rate of global averaged sea level rise was 1.7 mm yr between 1901 and 2010“
Historical Hemispheric Temperatures Rose 2.0°C/Decade.
According to a new paper, the Bølling Warming event 14,700 years ago raised the surface temperature for the entire Northern Hemisphere by 4 to 5°C within a few decades.  This is a hemispheric warming rate of approximately 2.0°C per decade, which is 40 times faster than the 0.05 °C per decade global warming rate since 1850 (and 1998).
