Ser man på Arktisk sjøis i den senere tiden så varierer den mellom 5 - 15 mill km2 ( www.climate4you.com ), mens figuren i artikkelen
There Has Been No Significant Net Change In Arctic Sea Ice Extent In The Last 80+ Years
http://notrickszone.com/#sthash.6M9cNKaz.3ZpJhgwq.dpuf
tyder på en variasjon mellom 5,5 - 7,5 mill km2.
Tatt i betraktning dårlige målemetoder før satellittene så er det ikke så verst, men det var antagelig ikke så mye mindre is før satellittene. Hvis det var tilfelle så har vi intet å frykte av global oppvarming. Spleising av de 2 figurene gir da et fordelaktig bilde for alarmistene.
Artikkelen avslører også hvordan klimaalarmistene "ommgår sainheita":
"For example, the IPCC referenced NOAA satellite data that extended back to 1972, not 1979, in the first UN report (1990). It showed that there had been a slight increasing trend in sea ice for 1972-1990 due to the low extent recorded during the early 1970s, and the very high extent in the late 1970s, when the current satellite datasets begin. Now, the IPCC (and NOAA, NSIDC) discard the 1972-1978 data from the sea ice record, instead using 1979 as the starting point, or the year with the highest sea ice extent since the early 20th century. This way, the decline in sea ice extent to the present can be steepened considerably in modern graphics."
