At this particular time of political and social turmoil,
a little more coherence, clarity, and if the author may add, circumscription in the EU asylum policy is essential.
Peterson and Haug 2006 and Newton et al 2006, for example, attribute the
coherence to latitudinal migrations of the ITCZ, hypothesizing that it (and other patterns) was further north in the Medieval period and further south in the
Little Ice Age, explaining antiphase changes in precipitation whereby northerly tropical sites became drier in the
Little Ice Age (Cariaco, Yucatan etc 15N or so) while
more southerly tropical sites became wetter in the
Little Ice Age (Lake Titicaca, Lake Malawi, Quelccaya etc. all at 10S or so).
