“…Humid conditions are also inferred for the Guajira Peninsula, northeast of the CGSM (Figures 1 and 6), from development of a mangrove forest that expanded under a delicate balance between increased tidal influence, a consequence of sea level rise, and prevailing humid conditions (Urrego et al, 2013). Elsewhere around the Caribbean, in such places as the Cariaco Basin, north of Venezuela (Haug et al, 2001), and Lake Miragoane, Haiti (Hodell et al, 1991), humid conditions are also inferred for this time. Mayewski et al (2004) proposed that generally humid climates characterized the entire Caribbean during that period.…”

We analyzed diatoms, lithology, and stable isotopes in a sediment core from the Ciénaga Grande de Santa Marta lagoon to reveal the history of late Holocene relative sea level rise and the ontogeny of the lagoon on the Caribbean coast of Colombia. At ~5300 cal. yr BP, the area was characterized by shallow, freshwater ponds that were prone to seasonal flooding. From ~4250 to ~2060 cal. yr BP, these ponds became brackish as relative sea level began to rise, and since ~2060 cal. yr BP, marine conditions have prevailed. In addition to tracking relative sea level rise, we also investigated periods of greater and lesser precipitation during times of brackish and marine conditions, respectively, as indicated by diatom-inferred changes in water salinity and shifts in the source of sediment organic matter. Comparisons with other regional paleoenvironmental records suggest that humid climate conditions prevailed in the Caribbean until about 4000 cal. yr BP. After that time, climate became more variable, with drier conditions registered from ~ 4000 to 2000 cal. yr BP. Wetter conditions returned after ~2000 cal. yr BP.

“…In contrast, a slowdown of the AMOC, as might be caused by a freshening of the North Atlantic during Heinrich events, strengthens the northeast Trade Winds and results in a southern migration of the ITCZ (Timmermann et al, 2005;Zhang and Delworth, 2005;Cheng et al, 2007). Changes in solar insolation forced by orbital precession also influence the position of the ITCZ on long time scales with more precipitation in the Caribbean when perihelion occurs during boreal summer (Hodell et al, 1991;Haug et al, 2001;Clement et al, 2004). Additional factors that can influence the Atlantic ITCZ meridional position on shorter time scales include the El Niñ o Southern Oscillation and North Atlantic Oscillation (Giannini et al, 2000(Giannini et al, , 2001a.…”

a b s t r a c tDrill cores obtained from Lake Peté n Itzá , Peté n, Guatemala, contain a $85-kyr record of terrestrial climate from lowland Central America that was used to reconstruct hydrologic changes in the northern Neotropics during the last glaciation. Sediments are composed of alternating clay and gypsum reflecting relatively wet and dry climate conditions, respectively. From $85 to 48 ka, sediments were dominated by carbonate clay indicating moist conditions during Marine Isotope Stages (MIS) 5a, 4, and early 3. The first gypsum layer was deposited at $48 ka, signifying a shift toward drier hydrologic conditions and the onset of wet-dry oscillations. During the latter part of MIS 3, Peté n climate varied between wetter conditions during interstadials and drier states during stadials. The pattern of clay-gypsum (wet-dry) oscillations during the latter part of MIS 3 ($48-23 ka) closely resembles the temperature records from Greenland ice cores and North Atlantic marine sediment cores and precipitation proxies from the Cariaco Basin. The most arid periods coincided with Heinrich Events when cold sea surface temperatures prevailed in the North Atlantic, meridional overturning circulation was reduced, and the Intertropical Convergence Zone (ITCZ) was displaced southward. A thick clay unit was deposited from 23 to 18 ka suggesting deposition in a deep lake, and pollen accumulated during the same period indicates vegetation consisted of a temperate pine-oak forest. This finding contradicts previous inferences that climate was arid during the Last Glacial Maximum (LGM) chronozone (2172 ka). At $18 ka, Peté n climate switched from moist to arid conditions and remained dry from 18 to 14.7 ka during the early deglaciation. Moister conditions prevailed during the warmer Bolling-Allerod (14.7-12.8 ka) with the exception of a brief return to dry conditions at $13.8 ka that coincides with the Older Dryas and meltwater pulse 1A. The onset of the Younger Dryas at 12.8 ka marked the return of gypsum and hence dry conditions. The lake continued to precipitate gypsum until $10.3 ka when rainfall increased markedly in the early Holocene.

“…We consider the estimates based on correlation between paleomagnetic intensity measured in sediment records close to Greenland and cosmogenic isotopes fluxes measured in the GISP2 Greenland ice core record (Stoner et al 2000) as most reliable, and use these for data comparison. Heinrich event ages, and hence the Lake Tulane record below TP4, have been updated to the new Greenland Ice Core Chronology 2005 (GICC05), which is based on layer counting of the NGRIP ice core back to 60 ka Svensson et al 2008) Hodell et al (1991) and Poore et al (2004) indicate that during the Holocene the Loop Current was mainly controlled by the effect of summer insolation on ITCZ position. Nürnberg et al (2008) reconstructed SSTs and sea surface salinities in the northeastern GoM (Florida margin) over the past 400 kyr.…”

Impact of the Atlantic Warm Pool on precipitation and temperature in Florida during North Atlantic cold spells

Recurrent phases of increased pine at Lake Tulane, Florida have previously been related to strong stadials terminated by so-called Heinrich events. The climatic significance of these pine phases has been interpreted in different ways. Using a pollen-climate inference model, we quantified the climate changes and consistently found that mean summer precipitation (P JJA ) increased (0.5-0.9 mm/day) and mean November temperature increased (2.0-3.0°C) during pine phases coeval with Heinrich events and the Younger Dryas. Marine sea surface temperature records indicate that potential sources for these moisture and heat anomalies are in the Gulf of Mexico and the western tropical Atlantic. We explain this low latitude warming by an increased Loop Current facilitated by persistence of the Atlantic Warm Pool during summer. This hypothesis is supported by a climate model sensitivity analysis. A positive heat anomaly in the Gulf of Mexico and equatorial Atlantic best approximates the polleninferred climate reconstructions from Lake Tulane during the (stadials around) Heinrich events and the Younger Dryas.
