Many moms - to - be — especially those with darker skin or who live in northern latitudes — don't get enough vitamin D, and deficiency is associated with higher rates of prenatal infections, preeclampsia, preterm birth and Cesarean section.

«Ever since the lakes and seas were discovered, we've been wondering why they're concentrated at high northern latitudes,» said Elizabeth (Zibi) Turtle, a Cassini imaging team associate based at the Johns Hopkins Applied Physics Laboratory, Laurel, Md. «So, seeing that there's something special about the surface in this region is a big clue to help narrow down the possible explanations.»

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

«Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

The intensification of the Northern Hemisphere circulation is reflected in the positive phase of the Arctic Oscillation (AO), associated with higher - than - normal surface pressure south of about 508 N and lower - than - normal surface pressure over the high northern laNorthern Hemisphere circulation is reflected in the positive phase of the Arctic Oscillation (AO), associated with higher - than - normal surface pressure south of about 508 N and lower - than - normal surface pressure over the high northern lanorthern latitudes.

2.10 All model simulations, whether they were forced with increased concentrations of greenhouse gases and aerosols or with increased concentrations of greenhouse gases alone, show the follow - ing features: greater surface warming of the land than of the sea in winter; a maximum surface warming in high northern latitudes in winter... All these changes are associated with identifiable physical mechanisms.

GMT drops initially at glacial inception in response to decreased summer radiation at high northern latitudes that would have led to equatorward extension of sea ice and snow cover with associated cooling from increased albedo.

Only a strong reduction in summer insolation at high northern latitudes, along with associated feedbacks, can end the current interglacial.
