Marine N 2 O emissions during a Younger Dryas-like event
Past variations in atmospheric nitrous oxide (N 2 O) allow important insight into abrupt climate events. Here, we investigate marine N 2 O emissions by forcing the Bern3D Earth System Model of Intermediate Complexity with freshwater into the North Atlantic. The model simulates a decrease in marine N 2 O emissions of about 0.8 TgN yr −1 followed by a recovery, in reasonable agreement regarding timing and magnitude with isotope-based reconstruction…
Palynological insights into global change impacts on Arctic vegetation, fire, and pollution recorded in Central Greenland ice
Arctic environments may respond very sensitively to ongoing global change, as observed during the past decades for Arctic vegetation. Only little is known about the broad-scale impacts of early and mid 20th-century industrialization and climate change on remote Arctic environments. Palynological analyses of Greenland ice cores may provide invaluable insights into the long-term vegetation, fire, and pollution dynamics in the Arctic region. We pres…

Timing and climate forcing of volcanic eruptions for the past 2,500 years
A stratigraphic framework for abrupt climatic changes during the Last Glacial period based on three synchronized Greenland ice-core records
Due to their outstanding resolution and well-constrained chronologies, Greenland ice-core records provide a master record of past climatic changes throughout the Last Interglacial–Glacial cycle in the North Atlantic region. As part of the INTIMATE (INTegration of Ice-core, MArine and TErrestrial records) project, protocols have been proposed to ensure consistent and robust correlation between different records of past climate. A key element of th…
Years of Cosmic Radiation and Solar Activity From Ice Cores and Tree Rings
Understanding the temporal variation of cosmic radiation and solar activity during the Holocene is essential for studies of the solar-terrestrial relationship. Cosmic-ray produced radionuclides, such as 10 Be and 14 C which are stored in polar ice cores and tree rings, offer the unique opportunity to reconstruct the history of cosmic radiation and solar activity over many millennia. Although records from different archives basically agree, they a…
High-Resolution Greenland Ice Core Data Show Abrupt Climate Change Happens in Few Years
The last two abrupt warmings at the onset of our present warm interglacial period, interrupted by the Younger Dryas cooling event, were investigated at high temporal resolution from the North Greenland Ice Core Project ice core. The deuterium excess, a proxy of Greenland precipitation moisture source, switched mode within 1 to 3 years over these transitions and initiated a more gradual change (over 50 years) of the Greenland air temperature, as r…
Orbital and Millennial Antarctic Climate Variability over the Past 800,000 Years
A high-resolution deuterium profile is now available along the entire European Project for Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine isotope stage 20.2, â 1⁄4800,000 years ago. Experiments performed with an atmospheric general circulation model including water isotopes support its temperature interpretation. We assessed the general correspondence between Dansgaard-Oeschger events and their smoothed Ant…
A new Greenland ice core chronology for the last glacial termination
We present a new common stratigraphic timescale for the North Greenland Ice Core Project (NGRIP) and GRIP ice cores. The timescale covers the period 7.9–14.8 kyr before present and includes the Bølling, Allerød, Younger Dryas, and early Holocene periods. We use a combination of new and previously published data, the most prominent being new high‐resolution Continuous Flow Analysis (CFA) impurity records from the NGRIP ice core. Several investigat…
Holocene carbon-cycle dynamics based on CO2 trapped in ice at Taylor Dome, Antarctica
Remote Sensing of Atmospheric Trace Gases
The investigation of changes in ozone concentration and of the increase of the greenhouse effect requires simultaneous and global observations of atmospheric trace species. Fourier transform infrared (FTIR) spectrometers are especially appropriate for this measurement task owing to their ability to detect wide spectral intervals with high spectral resolution. Experiments using FTIR to measure trace species have been used in remote sensing during …
