In climate Onion Blog was recently pointed out that the ZAMG now been announced by Dr. Boehm in my interview for the fall (see: has been
Part II), a climate change information portal
online:
people in conversation.
we take a look at the statements on the MWP.
Under the heading
Palaeoclimatology: 2000 years
is received on the climate of the last two Millennia read
in the Holocene AD time cooler and milder portions from each other: Moderately cool conditions in the migration period was followed by the medieval climate optimum, the Little Ice Age gave way to the modern rise in temperature.
It is likely that climate changes were at least Northern Hemisphere. A recent multi-proxy reconstruction proposed for late antiquity and early middle age slightly supercooled conditions, compared to 20 Century, is of a climatic deterioration as Mitauslöser of migration, however, nothing should be noted (Fig. 1, top
). The favorable climate of the Middle Ages not only enabled extensive vineyards in Europe, including training of the States, growth of cities and population growth fall into this time.
From a MWP is however not mentioned. Dr. Boehm and Dr. Reitner talking about "climate change" and a "medieval climate optimum" or "favorable climate of the High Middle Ages.
In regard to the period of 2000 years can not in good conscience speak my opinion of climate fluctuations, in relation to the Medieval Warm Period, the Little Ice Age and entering the heating phase with the expiry of the Little Ice Age. The concept of variation may sound neutral, but at the same time relativized. "Wavering" the climate always does. The changes still remains that within the last two Millennia clear quantifiable "fluctuations" have occurred, the different temperature levels periodicity can be supplied. Only then be possible in my eyes comparisons. to speak
From a medieval climate optimum, in my view also fails. Optimum insinuates no heating phase, no phase of average warmer temperatures, but usually a heat peak, an overcoming of the "Second Steps" to the summit - to use a picture - but not the higher average temperatures during this period - higher mountains in the Himalayas.
Sogesehen we have the modern optimum, at this stage, reached in 1998 for many parts of the world. For parts of Scandinavia already in the 30s the last century. It would also be interesting if you would point out that parts of South America for the modern optimum could then fall into the 18th century.
The advantage of the concept of a Medieval Warm Period, fair enough, where necessary, specifiable in a late-or high-medieval warm period was, I have already discussed in detail ( http://mittelalterlichewarmperiode.blogspot.com/2010_10_01_archive.html ).
It can also include much that is the use of this construct in climatology still widespread, as others mentioned by me 50 studies for the years 2009/10 (1st half), published in respected journals such as The Holocene
,
PALAEOGEOGRAPHY, Palaeoclimatology, Palaeoecology
,
Quaternary Research, Quaternary International
or
Quaternary Science Review
show .
In addition, there seems to be consensus that the higher average temperatures during the Medieval Warm Period for Some were perceived as "during the subsequent Little Ice Age", as even critics of the MWP, Bradley, Hughes and Diaz - if granted only for the Northern Hemisphere.
also seems wrong to me to be the following statement:
"For the Northern Hemisphere, backed by numerous studies as for the Southern: This would be my opinion this sentence follows Hemisphere by some studies as likely to be accepted that there was a period in the Middle Ages was that on average warmer temperatures than had the following period, known as the Little Ice Age
- though in relation to the respective regions studied. To these facts into account, it is called in climatology from a
medieval warm period
