Scientists know the last reversal took place during the Stone Age, but they have little information about the duration of this phenomenon and when the next "flip" might occur. Related: Why You (Probably) Shouldn't Worry About Earth's Magnetic Poles Flipping You may like The next ice age...
The last complete reversal of the Earth’s magnetic field, the so-called Laschamps event, took place 42,000 years ago. Radiocarbon analyses of the remains of kauri trees from New Zealand now make it possible for the first time to precisely time and analyze this event and its associate...
The oldest (sandy) loess, located on top of the terrace dated at about 1 Ma, was deposited at the end of the Lower Pleistocene before the B-M magnetic reversal (Antoine et al., 2000, 2003a). The St. Vallier loess, near Lyon, is among the oldest in Europe, having been dated to ...
Although no detailed correlation can be established between the two sections, they both encompassed the Matuyama-Brunhes (M-B) reversal. Stepwise alternating field (AF) and thermal demagnetization in air and in vacuum accompanied by investigations of the rock magnetic properties allowed us to identify...
In addition to an expected reduction in both recurrent and non-recurrent geo- magnetic storms during the MM, the expected poleward motion of the nominal auroral oval position may further help explain the dearth of auroral reports from that period for all but the most northerly locations15. ...
are largely driven by the Southern annular mode (SAM)6: the main pattern of atmospheric climate variability over the Southern Ocean, which is typically described as the pressure difference between mid and high austral latitudes7. The SHW belt shifts poleward in the positive SAM polarity and expan...

4), consistent with a reduced, but non-negligible poleward heat transport in the eastern part of the northern seas. Due to summer melting of surrounding ice sheets, the salinity in the central and eastern seas was lower than today, strengthening the stratification of the upper part of the ...
Coinciding with global warming, Arctic sea ice has rapidly decreased during the last four decades and climate scenarios suggest that sea ice may completely disappear during summer within the next about 50–100 years. Here we produce Arctic sea ice biomar
and SST or magnetic records for sediment cores located poleward of ~38°N and ~40°S. New cores were added to fill gaps with respect to the available geographical and water depth coverage, and additional radiocarbon dates were produced to improve the existing age models of some cores (Online...
