The prescience of paleoclimatology and the future of the Antarctic ice sheet
The emerging view that the West Antarctic ice sheet is in the early stage of collapse owes as much to paleoclimatology as to contemporary observations.

A Closer Earth and the Faint Young Sun Paradox: Modification of the Laws of Gravitation or Sun/Earth Mass Losses? [PDF]
Given a solar luminosity LAr = 0.75L0 at the beginning of the Archean 3.8 Ga ago, where L0 is the present-day one, if the heliocentric distance, r, of the Earth was rAr = 0.956r0, the solar irradiance would have been as large as IAr = 0.82I0.

The varved sediments of the Pyrenean Lake Montcortès (Pallars Sobirà, Lleida) embody a unique continuous high-resolution (annual) paleoarchive of the last 3000 years for the circum-Mediterranean region.

The Magnitude of Surface Ocean Acidification and Carbon Release During Eocene Thermal Maximum 2 (ETM-2) and the Paleocene-Eocene Thermal Maximum (PETM) [PDF]
Eocene Thermal Maximum 2 (ETM-2; 54.1 Ma) was the second largest Eocene hyperthermal. Like the Paleocene-Eocene Thermal Maximum (PETM), ETM-2 was characterized by massive carbon emissions and several degrees of global warming and thus can serve as a case

Growing season thermal climate reconstructed at six pine stands in northern Lapland [PDF]
At the northern coniferous timberline of the boreal region, growing season temperature is generally the major environmental factor limiting the growth processes of Scots pine (Pinus sylvestris L.). Variations in annual ring-widths of pines can be related

Additions to the Last Millennium Reanalysis Multi-Proxy Database
Progress in paleoclimatology increasingly occurs via data syntheses. We describe additions to a collection prepared for use in paleoclimate state estimation, specifically the Last Millennium Reanalysis (LMR).

Reevaluating Links Between Meteorite Impacts and Early Cenozoic Global Warming
The Paleocene‐Eocene Thermal Maximum (PETM) and the lower Chron 29n hyperthermal event were recently proposed to have been triggered by the meteorite impacts that formed the Marquez Dome (Texas, USA; 58.3 ± 3.1 Ma) and Boltysh (Ukraine; 65.39 ± 0.14 Ma ...

Snowpack signals in North American tree rings
Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn have intensified hydrological droughts in western North America.

Studying Africa's hydroclimate history over the last 2000 years [PDF]
Water-resource availability is one of the most important environmental factors on which Africa’s agricultural societies are reliant. However, our knowledge of the natural background variability of rainfall and drought over Africa is currently still ...
