The IPCC 2013 climate report. Facts versus Fictions. Part 2 continued

Fig 3 Fig 4 and Fig 5.

                                    fig 3 shows more than 20 periods of warming in the past 500 years.(Greenland GISP2 ice core, Easterbrook 2011).   Fig 4 shows temperature reconstruction for the northern Hemisphere up to 2000 AD showing the modern warm period is not exceptional! Temperatures of the Medieval Warm Period and Roman Warm Period were higher than recent temperatures!    Fig 5 shows that more than 90 percent of temperatures during the last 10 000 years were significantly warmer than recent warming. ( Cuffy and Clow  1997; Alley 2000).

From the IPCC 2013 Report:  Each of the three decades has been successively warmer at the Earth`s surface than any preceding decade since 1850.  In the Northern Hemisohere 1983-2012 cwas likely the warmists 30 year period of the last 1400 years.     As shown by the figures above from peer reviewed published scientific literature this statement is blatantly false.   nearly all the warming since the end of the Little Ice Age occurred long before CO2 could possibily have been  a causal factor

From the IPCC 2013 climate report:  Over the last two decades the Greenland and Antarctic ice sheets have been losing mass, glaciers have continued to shrink almost worldwide and Arctic sea ice and Northern Hemisphere spring snow cover have continued to decrease.   This is another lie!   The Antarctic ice sheet has not been losing mass---the East Antarctic ice sheet, which contains about 90 percent of the worlds fresh watetr, is not melting---it is growing!.   The same is true of the Antarctic ice shelf itself.  The only part of Antarctica that may be losing ice is the west Antarctic Peninsula, which contains less than 10 percent of Antarctic ice.  Temperatures at the South pole show no warming since records began in 1997! 

       Some melting occurred in Greenland during the 1978-1998 warming period but that is not at all unusual.

Temperaturesin Greenland were warmer in the 1930s than during the recent warming.   Arctic sea ice EXPANDED by 60 percent in 2013.  Antarctic sea ice has increased by about 1 million Km2 (but the IPCC makes no mention of this!).  The total extent of global sea ice has not diminished in recent decades.

The statement by the IPCC that Northern hemisphere snow cover has continued to decrease in extent is false.  Snow extent in the northern hemisphere shows no decline since 1967 and five of the six snowiest winters have occurred since 2003.

The above figure shows snow extent in the northern hemisphere since 1967.
