متن کاملBipolar modulation of millennial-scale West African monsoon variability during the last glacial (75,000e25,000 years ago)
Time series of planktonic foraminiferal d18O and Ba/Ca-based sea surface salinity (SSS) estimates from the eastern Gulf of Guinea (eastern equatorial Atlantic) indicate changes in runoff that reflect variability of spatially integrated precipitation over the equatorial West African monsoon area. Millennial-scale and recurring runoff-induced SSS rises and declines in the range of 1.5 and 2 psu (...
متن کاملAmerica`s Strategies against IR during the Last Forty Years
The Islamic Revolution, as the greatest historical evolution of contemporary times, has caused America`s interests face many challenges. Understanding the tools and strategies used by the United States against the Islamic Republic of Iran helps us to better understand and confront the country. In this regard, using the theory of invasive realism, American strategies against the Islamic Republic...
متن کاملClimate variability and human impact in South America during the last 2000 years: synthesis and perspectives from pollen records
An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia. Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records of past vegetation change. For South America, however, the full potential of vegetation records for evaluating and improving climate models ha...
متن کاملMajor shifts in multidecadal moisture variability in the Mid‐Atlantic region during the last 240 years
[1] The paucity of high‐resolution paleoclimate records limits our ability to extend instrumental data into a longer time‐frame and to better understand multidecadal climate variations in the Mid‐Atlantic region. Here we present an ∼2 year‐resolution endogenic calcite dO record for the last ∼240 years from a freeze core at White Lake in northern New Jersey. The dO data, consistent with the pale...
