Temperatures, Sea Levels ‘Naturally’ Rise 30 ‚Äì 40 Times Faster Than Today’s Rates
Modern Temperatures Only Rising 0.05°C/Decade
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.
IPCC AR5 (2013): “The globally averaged combined land and ocean surface temperature data as calculated by a linear trend, show a warming of 0.85¬∞C over the period 1880 to 2012, when multiple independently produced datasets exist. The total increase between the average of the 1850‚Äì1900 period and the 2003‚Äì2012 period is 0.78 ¬∞C, based on the single longest dataset available 4 (see Figure SPM.1). … [T]he rate of warming over the past 15 years (1998‚Äì2012; 0.05 ¬∞C per decade), which begins with a strong El Ni√±o, is smaller than the rate calculated since 1951 (1951‚Äì2012; 0.12 ¬∞C per decade).”
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).
Historical Sea Levels Rose 5.3 Meters/Century
Central Greenland’s surface temperatures rose by as much as 12¬∞C during this time frame (14,700 years ago to 14,500 years ago). Consequently, glaciers and ice sheets disintegrated rapidly and sea levels rose by about 18 meters (“12-22 m”) in 340 years. An 18 m rise in 340 years is the equivalent of 5.3 meters per century, which is more than 30 times faster than the rate of sea level change (0.17 m per century) between 1901 and 2010.
And back in the 1990’s they made a totaly putrid movie with Kevin Cosner WATERWORLD which shows the world in the future as all floded becuase of Global Warming and Cosner playing some amphibius goofball named Mariner swimming dolphin style and making a total idiot of himself while doing so. Global Warming never mind for the facts that the same liberal rag TIME which was blabbering this Global Warming/Climate change back in the 1990s was also blabbering about Global Cooling back in the 1970’s
