Moisture transport across Central America as a positive feedback on abrupt climatic changes
Moisture transport from the Atlantic to the Pacific ocean across Central America leads to relatively high salinities in the North Atlantic Ocean and contributes to the formation of North AtlanticExpand

Road Traffic Data: Collection Methods and Applications
The mission of the IPTS is to provide customer-driven support to the EU policy-making process by researching science-based responses to policy challenges that have both a socioeconomic and a scientific or technological dimension. Expand

Holocene and Eemian sea surface temperature trends as revealed by alkenone and Mg/Ca paleothermometry
In this study we review a global set of alkenone- and foraminiferal Mg/Ca-derived sea surface temperatures (SST) records from the Holocene and compare them with a suite of published Eemian SSTExpand

ITCZ rather than ENSO signature for abrupt climate changes across the tropical Pacific
Latitudinal movements of the Intertropical Convergence Zone (ITCZ), analogous to its present-day seasonal shifts, and El Nino Southern Oscillation (ENSO)-type variability both potentially impactedExpand

Modes of eastern equatorial Pacific thermocline variability: Implications for ENSO dynamics over the last glacial period
[1] Changes in El Nino–Southern Oscillation (ENSO) variability are difficult to extract from paleoceanographic reconstructions because they are superimposed on changes in seasonal variability thatExpand

Geomagnetic moment variation and paleomagnetic excursions since 400 kyr BP: a stacked record from sedimentary sequences of the Portuguese margin
Abstract A paleomagnetic study was performed in clayey-carbonate sedimentary sequences deposited during the last 400 kyr on the Portuguese margin (Northeast Atlantic Ocean). Declination andExpand

Biofuel Support Policies in Europe: Lessons Learnt for the Long Way Ahead
Biofuel consumption in the EU is growing rapidly but major efforts will need to be undertaken if the EU's objectives for 2010 and beyond are to be achieved. This article analyses the strengths andExpand

What does leaf wax δD from a mixed C3/C4 vegetation region tell us?
Abstract Hydrogen isotope values (δD) of sedimentary terrestrial leaf wax such as n-alkanes or n-acids have been used to map and understand past changes in rainfall amount in the tropics because δDExpand

Contrasting evolution of sea surface temperature in the Benguela upwelling system under natural and anthropogenic climate forcings
We present alkenone-derived Sea Surface Temperature (SST) records from three marine cores collected within the southern Benguela Upwelling System (BUS) spanning the last 3 ka. The SST evolution overExpand

Robust global ocean cooling trend for the pre-industrial Common Era
Knowledge of natural climate variability is essential to better constrain the uncertainties in projections of twenty-first-century climate change 1–5. The past 2,000 years (2 kyr) have emerged as aExpand
