LIA was globaal?

It was initially believed that the LIA was a global phenomenon; it is now less clear if this is true. The Intergovernmental Panel on Climate Change (IPCC), based on Bradley and Jones, 1993; Hughes and Diaz, 1994; Crowley and Lowery, 2000 describes the LIA as "a modest cooling of the Northern Hemisphere during this period of less than 1°C," and says, "current evidence does not support globally synchronous periods of anomalous cold or warmth over this timeframe, and the conventional terms of 'Little Ice Age' and Medieval Warm Period appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries."[3] There is evidence, however, that the Little Ice Age did affect the Southern Hemisphere.


Was ze in Buenos Aires lijkt me een toepasselijkere vraag.

Ik zal je zogezegd weer stalken, maar je lult hier toch wel weer serieus uit je nek.

Als jij het allemaal wel weet, schroom dan niet om aanpassingen te maken:

Zucht. There we go again. Je kan niet zeggen dat het lokaal was, en er dan verschillende regio's wereldwijd uitpikken waar het ook plaatsvond.

Belgisch onderzoek wijst nogthans op een globale LIA:

Our results support the fact that the Little Ice Age was a global event, not only restricted to the Northern Hemisphere.

Five centuries of climate change in Australia: the view from underground. Pollack, H. N., Huang, S. and Smerdon, J. E. 2006.

ISSN 0267â??8179.

ABSTRACT: Fifty-seven borehole temperature profiles from across Australia are analysed to reconstruct a ground surface temperature history for the past five centuries. The five-hundred-year
reconstruction is characterised by a temperature increase of approximately 0.5 K, with most of the warming occurring in the 19th and 20th centuries. The 17th century was the coolest interval of the
five-century reconstruction. Comparison of the geothermalreconstruction to the Australian annual surface air temperature time series in their period of overlap shows excellent agreement. The full geothermal reconstruction also agrees well with the low-frequency component of dendroclimatic reconstructions from Tasmania and New Zealand. The warming of Australia over the past five centuries is only about half that experienced by the continents of the Northern Hemisphere in the
same time interval.

"For several hundred years until about 1400AD, at any one time, more of the West was experiencing drought than occurred for centuries after. This has been called a Medieval Megadrought. During Medieval times the American West was an even drier climate than the current already arid one. Apparently this very arid climate greatly stressed the social organization of Indian societies at the time, according to archaeologists. Around about the fifteenth century the climate shifted to being much wetter and remained that way for several hundred years, coinciding with the Little Ice Age, a period when climate was cooler than now around the world. There also appears to have been a return to a more drought-prone climate in the last two centuries."

China:

Oscillating warm and cold periods could be related to the 20th century warm period, the Little Ice Age, the Medieval Warm Period, the Dark Ages Cold Period, and the Roman Warm Period.

The most recent cool, dry event was that associated with the Little Ice Age from about AD 1500 to 1800.

Niet globaal wil nog niet zeggen enkel in Brussel.
In de laatste zin van het stuk dat ik quote staat ook dat er evidentie is voor een LIA in de zuidelijke hemisfeer.

En dank je, de koude winters in Buenos Aires in 1921 kon dus veroorzaakt zijn door de LIA.

Het koude voorjaar dat Argentinië in 2007 gekend heeft is dan weer een gevolg van de GCC.
