Abstract Reproducible climate reconstructions of the Common Era (1 CE to present) are key placing industrial-era warming into context natural climatic variability. Here we present a community-sourced database temperature-sensitive proxy records from PAGES2k initiative. The gathers 692 648 locations, including all continental regions and major ocean basins. trees, ice, sediment, corals, speleothems, documentary evidence, other archives. They range in length 50 2000 years, with median 547...
In this paper, we compile the current surface seawater C 37 alkenone unsaturation (U K′ ) measurements (n = 629, −1 to 30°C temperature range) derive a global, field‐based calibration of U with production temperature. A single nonlinear “global” water accurately predicts temperatures over diversity modern‐day oceanic environments and alkenone‐synthesizing populations (T −0.957 + 54.293(U − 52.894(U 2 28.321(U 3 , r 0.97, n 567). The mean standard error estimation is 1.2°C insignificant bias...
The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide changing ocean chemistry disrupting species throughout food webs, fundamental capacity regulate been altered. However, key technical, organizational, conceptual scientific barriers have prevented identification policy levers for sustainability transformative action. Here, we recommend strategies address these...
Abstract. On the basis of a multi-proxy approach and strategy combining lacustrine marine records along north–south transect, data collected in central Mediterranean within framework collaborative project have led to reconstruction high-resolution well-dated palaeohydrological assessment their spatial temporal coherency. Contrasting patterns changes been evidenced Mediterranean: south (north) around 40° N latitude, middle part Holocene was characterised by lake-level maxima (minima), during...
Abstract. The Mediterranean region and the Levant have returned some of clearest evidence a climatically dry period occurring around 4200 years ago. However, regional is controversial contradictory, issues remain regarding timing, progression, articulation this event. In paper, we review from selected proxies (sea-surface temperature, precipitation, temperature reconstructed pollen, δ18O on speleothems, lacustrine carbonate) over Basin to infer possible climate patterns during interval...
Faced with sea level rise and the intensification of extreme events, human populations living on coasts are developing responses to address local situations. A synthesis literature coastal adaptation allows us highlight different strategies. Here, we analyze these strategies according complexity their implementation, both institutionally technically. First, distinguish two opposing paradigms – fighting against rising levels or adapting new climatic conditions; second, observe integrated...
This paper reviews the methodological and practical issues relevant to ways in which natural scientists, historians archaeologists may collaborate study of past climatic changes Mediterranean basin. We begin by discussing methodologies these three disciplines context consilience debate, that is, attempts unify different research address similar problems. demonstrate there are a number similarities fundamental methodology between history, archaeology, sciences deal with ("palaeoenvironmental...
A decadal resolution time series of sea surface temperature (SST) spanning the last two millennia is reconstructed by combining a proxy record from new sediment sequence with previously published data core MD99–2275, north Iceland. The alkenone based SST reconstruction validated historic observational and compared to similar temporal obtained RAPiD21–3K, in subpolar North Atlantic. paleorecords show consistent multidecadal scale coolings throughout interval expressions during contrasted...
Abstract. Despite a large number of studies, the long-term and millennial to centennial-scale climatic variability in Mediterranean region during last deglaciation Holocene is still debated, including southern Central Mediterranean. In this paper, we present new marine pollen sequence (core MD04-2797CQ) from Siculo-Tunisian Strait documenting regional vegetation changes Holocene. The MD04-2797CQ shows that semi-desert plants dominated vegetal cover between 18.2 12.3 ka cal BP, indicating...
