A 420-year history of strontium/calcium, uranium/calcium, and oxygen isotope ratios in eight coral cores from the Great Barrier Reef, Australia, indicates that sea surface temperature and salinity were higher in the 18th century than in the 20th century. An abrupt freshening after 1870 occurred simultaneously throughout the southwestern Pacific, coinciding with cooling tropical temperatures. Higher salinities between 1565 and 1870 are best explained by a combination of advection and wind… 

Climate and hydrographic variability in the Indo‐Pacific Warm Pool during the last millennium

Planktonic foraminiferal Mg/Ca and δ18O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long‐term cooling and freshening trend, as well as

Coral‐Derived Western Pacific Tropical Sea Surface Temperatures During the Last Millennium

Reconstructions of ocean temperatures prior to the industrial era serve to constrain natural climate variability on decadal to centennial timescales, yet relatively few such observations are

Decadal-Scale SST and Salinity Variations in the Central Tropical Pacific: Signatures of Natural and Anthropogenic Climate Change

Accurate projections of future temperature and precipitation patterns in many regions of the world depend on quantifying anthropogenic signatures in tropical Pacific climate against its rich

Rapid reorganization in ocean biogeochemistry off Peru towards the end of the Little Ice Age

Abstract. Climate and ocean ecosystem variability has been well recognized during the twentieth century but it is unclear if modern ocean biogeochemistry is susceptible to the large, abrupt shifts

Annual to interannual temperature variability in the Caribbean during the Maunder sunspot minimum

We reconstruct Caribbean seawater temperatures from sclerosponge Sr/Ca ratios using a specimen of Ceratoporella nicholsoni that grew at 20 m below sea level in a reef cave at Jamaica. We sample the

Abstract : Benthic and planktonic foraminiferal delta (exp 18) oxygen (delta(exp 18)Oxygen(sub c) from a suite of well-dated, high-resolution cores spanning the depth and width of the Straits of

Post-glacial evolution of the Indo-Pacific Warm Pool and El Niño-Southern oscillation

Enhancement of coastal upwelling and interdecadal ENSO‐like variability in the Peru‐Chile Current since late 19th century

Secular trends in coastal upwelling proxies from a sediment record at 23°S encompassing 250 years reveal two distinct stages separated by a transition period between AD 1820 and 1878. Persistent

'Little Ice Age' summer temperature variations: their nature and relevance to recent global warming trends

Climatic changes resulting from greenhouse gases will be superimposed on natural climatic variations. High-resolution proxy records of past climate can be used to extend our perspective on regional

The Little Ice Age as Recorded in the Stratigraphy of the Tropical Quelccaya Ice Cap

The analyses of two ice cores from a southern tropical ice cap provide a record of climatic conditions over 1000 years for a region where other proxy records are nearly absent and confirms the worldwide character of the Little Ice Age.

Global-scale temperature patterns and climate forcing over the past six centuries

Spatially resolved global reconstructions of annual surface temperature patterns over the past six centuries are based on the multivariate calibration of widely distributed high-resolution proxy

Decadal sea surface temperature variability in the subtropical South Pacific from 1726 to 1997 A.D.

Calibration with monthly sea surface temperature (SST) from satellite and ship measurements made in a grid measuring 1 degrees by 1 degrees over the period from 1981 to 1997 indicates that this Sr/Ca record is an excellent proxy for SST, and hemispheric symmetry suggests that tropical forcing may be an important factor in at least some of the decadal variability observed in the Pacific Ocean.

Influence of volcanic eruptions on Northern Hemisphere summer temperature over the past 600 years

A network of temperature-sensitive tree-ring-density chronologies provides circum-hemisphere information on year-by-year changes in summer warmth in different regions of the northern boreal forest.

A coral‐based reconstruction of Intertropical Convergence Zone variability over Central America since 1707

Seasonal movements of the Intertropical Convergence Zone (ITCZ) control precipitation patterns and cloud cover throughout the tropics. In this study we have reconstructed seasonal and interannual

The Evolution of Climate Over the Last Millennium

Present knowledge of changes in temperatures and two major circulation features—El Niño–Southern Oscillation (ENSO) and the North Atlantic Oscillations (NAO)—over much of the last 1000 years are reviewed, mainly on the basis of high-resolution paleoclimate records.
