Reversing the field Do terrestrial geomagnetic field reversals have an effect on Earth's climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the… 

How the Geomagnetic Field Influences Life on Earth - An Integrated Approach to Geomagnetobiology.

The GMF has a positive impact on living organisms, whereas a diminishing or disappearing GMF negatively affects living organisms.

Global Evolution and Dynamics of the Geomagnetic Field in the 15–70 kyr Period Based on Selected Paleomagnetic Sediment Records

Reconstructions of the geomagnetic field on long time scales are important to understand the geodynamo processes in the Earth's core. The geomagnetic field exhibits a range of variations that vary

Radiocarbon: A key tracer for studying Earth’s dynamo, climate system, carbon cycle, and Sun

Recent progress that has allowed the construction of better radiocarbon age calibration curves are reviewed and the resulting insights that improve the understanding of climate processes, solar activity, geophysics, and the carbon cycle are discussed.

Analysis of E × B Drifts in Earth's Magnetosphere During Geomagnetic Reversals: Potential Consequences for Plasmasphere Behavior and Stability

Geomagnetic pole reversals occur frequently throughout geologic history, although one has not yet occurred in recorded time. Magnetohydrodynamic models of Earth's core have revealed that during a

Studies of the Earth’s Magnetic Field from Peninsular India: Contributions from CSIR-NGRI

Studies of the geomagnetic field and paleomagnetic phenomena were among the earliest disciplines of geophysics, which were launched in CSIR-NGRI since the early 1960s. Many firsts in the country as

Toward Reconciling Radiocarbon Production Rates With Carbon Cycle Changes of the Last 55,000 Years

Since it is currently not understood how changes in 14C production rate (Q), and in the carbon cycle, can be combined to explain the reconstructed atmospheric Δ14C record, we discuss possible reasons

On the tuning of plateaus in atmospheric and oceanic 14C records to derive calendar chronologies of deep-sea cores and records of 14C marine reservoir age changes

Abstract. As an extended comment on the paper by Sarnthein et al. (2020), we express strong reservations about the methodology of the so-called 14C plateau tuning (PT) technique used to date marine

Response to Comment on “A global environmental crisis 42,000 years ago”

Our paper about the impacts of the Laschamps Geomagnetic Excursion 42,000 years ago has provoked considerable scientific and public interest, particularly in the so-called Adams Event associated with

The Laschamps geomagnetic excursion recorded in continental sediments from southern Germany

We present palaeo- and rock magnetic results from a well-dated, 21 m-thick, Late Pleistocene continental sedimentary section located in southern Germany. Rock magnetic measurements reveal a complex
