Abstract Coral strontium‐to‐calcium ratios (Sr/Ca) provide quantitative estimates of past sea surface temperatures (SST) that allow for the reconstruction changes in mean state and climate variations, such as El Nino‐Southern Oscillation, through time. However, coral Sr/Ca are highly susceptible to diagenesis, which can impart artifacts 1–2°C typically on par with tropical signals interest. Mic...

This paper projects a climate change scenario using stochastic paleotemperature time series model and compares it to the prevailing consensus Autoregressive Integrated Moving Average Process Model (ARIMA). The parameter estimates of were below that established by anthropogenic experts governmental organs, such as IPCC (UN) over 100-year scenario. Results from ARIMA suggest current period temper...

A precise relative chronology for Greenland and West Antarctic paleotemperature is extended to 90,000 years ago, based on correlation of atmospheric methane records from the Greenland Ice Sheet Project 2 and Byrd ice cores. Over this period, the onset of seven major millennial-scale warmings in Antarctica preceded the onset of Greenland warmings by 1500 to 3000 years. In general, Antarctic temp...

Benthic foraminifera were cultured for five months at four temperatures (4, 7, 14 and 21 C) to establish the temperature dependence of foraminiferal calcite δ18O and Mg/Ca. Two Bulimina species (B. aculeata and B. marginata) were most successful in terms of calcification, adding chambers at all four temperatures and reproducing at 7 and 14 C. Foraminiferal δ18O values displayed ontogenetic vari...
