Sannheten om Antarktis
« på: 18.10.2018, 16:04:51 »
Media i spann med useriøse "klimaforskere" fortsetter å slå rundt seg med dommedagstaler om "det smeltende Antarktis" - selv når observasjonsdata viser en så knusende kontrast til modellenes "varmgang" at selv en blind høne kan se det.
La oss ikke drøvtygge for mye på den miserable uredeligheten i alarmistmiljøene en gang til, bare vise hva faktiske observasjoner sier:



Antarktis i motfase til nordlige halvkule siden 1979
- Havet rundt Antarktis har blitt kaldere siden 1979
- Sjøisen har økt i samme periode
- Massebalansen for landisen for hele Antarktis har økt i samme periode

Antarktis i motfase til nordlige halvkule også i forrige 30-års syklus
I kontrast til nedkjølingen og sjøisøkningen etter 1979, hadde Antarktis en oppvarming og isreduksjon i etterkrigsårene fram til 1980, mens nordlige halvkule da var i en avkjølingsfase.

Et lite malapropos:
Her tangerer vi altså det fabelaktige faktum for CO2-hypotesen at den synes å virke bare i en verdensdel om gangen  :o
Selvsagt en dundrende falsifikasjon av CO2-hypotesen, i tråd med den kalde etterkrigsperioden da CO2-nivået steg signifikant samtidig.

Kilder:
IPCC (2001):  “Another analysis of a 21-station data set from Antarctica by Comiso (1999) found a warming trend equivalent to 1.25°C per century for a 45-year record beginning in the 1950s but a slight cooling trend from 1979 to 1998. The slight cooling trend for this later 20-year period also was confirmed via analysis of surface temperatures over the whole continent, as inferred from satellite data.”

Fan et al., 2014:  “Sea surface temperatures and surface air temperatures decreased during 1979–2011, consistent with the expansion of Antarctic sea ice. In contrast, the Southern Ocean and coastal Antarctica warmed during 1950–1978.”

Sinclair et al., 2014: “We present the first proxy record of sea-ice area (SIA) in the Ross Sea, Antarctica, from a 130 year coastal ice-core record. High-resolution deuterium excess data show prevailing stable SIA [sea ice area] from the 1880s until the 1950s, a 2–5% reduction from the mid-1950s to the early-1990s, and a 5% increase after 1993.”

Miles et al., 2013: “Despite large fluctuations between glaciers—linked to their size—three epochal patterns emerged: 63 per cent of glaciers retreated from 1974 to 1990, 72 per cent advanced from 1990 to 2000, and 58 per cent advanced from 2000 to 2010.  … Indeed, several studies report increasing sea-ice concentrations in the study region from approximately 1980 to 2010, which is consistent with the predominance of glacier advance since 1990, when above-average sea-ice and fast-ice concentrations could have suppressed calving by increasing back-pressure on glacier termini. In contrast, reduced sea ice concentrations from the 1950s to the mid 1970s are consistent with glacier retreat during the 1960s and 1970s, when air temperatures were also increasing along the Pacific coast.”

Dagens Antarktiske sjøis tilsvarer forholdene 1897-1917
Edinburgh and Day, 2016: “In stark contrast to the sharp decline in Arctic sea ice, there has been a steady increase in ice extent around Antarctica during the last three decades, especially in the Weddell and Ross seas. In general, climate models do not to capture this trend … This comparison shows that the summer sea ice edge was between 1.0 and 1.7° further north in the Weddell Sea during this period but that ice conditions were surprisingly comparable to the present day [during 1897-1917] in other sectors.”

(press release): “We know that sea ice in the Antarctic has increased slightly over the past 30 years, since satellite observations began. Scientists have been grappling to understand this trend in the context of global warming, but these new findings suggest it may not be anything new. … The new study published in The Cryosphere is the first to shed light on sea ice extent in the period prior to the 1930s, and suggests the [sea ice] levels in the early 1900s were in fact similar to today“

Er det eksempler på motfase i kortere intervaller også? Kan endringer på hver sin halvkule kobles mot hverandre, eventuelt med en forsinkelse?
