GEOLOGICAL CARBON FLOWS PART-2

GEOLOGICAL CARBON FLOWS PART-2

Tambonthangchai Posted by: chaamjamal on: January 20, 2021 THIS POST IS A PRESENTATION OF SOURCES OF CARBON TRANSFERS FROM THE MANTLE TO THE SURFACE BY WAY OF SEEPAGE, HYDROTHERMAL VENTS, HYDROTHERMAL PLUMES, SUBMARINE VOLCANISM, AND ASSOCATED GEOLOGICAL ACTIVITY. THE CONTEXT OF THIS STUDY IS ANTHROPOGENIC GLOBAL WARMING (AGW) WHERE FOSSIL FUEL EMISSIONS ARE ASSUMED TO BE THE SOLE SOURCE OF CARBON EXTERNAL TO THE CARBON CYCLE. THE ANALYSIS IS PRESENTED IN TWO PARTS. PART-1 IS A SUMMARY AND INTERPRETATION OF THE DATA PRESENTED IN PART-2 IN THE CONTEXT OF AGW CLIMATE CHANGE: PART-2 IS A LITERATURE REVIEW ON THE SUBJECT …

Revising evidence of hurricane strikes on Abaco Island (The Bahamas) over the last 700 years

Revising evidence of hurricane strikes on Abaco Island (The Bahamas) over the last 700 years

Tyler S. Winkler, Peter J. van Hengstum, Jeffrey P. Donnelly, Elizabeth J. Wallace, Richard M. Sullivan, Dana MacDonald & Nancy A. Albury Scientific Reports volume 10, Article number: 16556 (2020) Abstract The northern Bahamas have experienced more frequent intense-hurricane impacts than almost anywhere else in the Atlantic since 1850 CE. In 2019, category 5 (Saffir-Simpson scale) Hurricane Dorian demonstrated the destructive potential of these natural hazards. Problematically, determining whether high hurricane activity levels remained constant through time is difficult given the short observational record (< 170 years). We present a 700-year long, near-annually resolved stratigraphic record of hurricane passage near Thatchpoint Blue Hole (TPBH) on …

A spatially explicit surface urban heat island database for the United States: Characterization, uncertainties, and possible applications

Science Direct T.Chakrabortyac, A.Hsubcd, D.Manyac, G.Sheriffe Received 3 April 2020, Revised 30 July 2020, Accepted 30 July 2020, Available online 13 August 2020. Abstract The urban heat island (UHI) effect is strongly modulated by urban-scale changes to the aerodynamic, thermal, and radiative properties of the Earth’s land surfaces. Interest in this phenomenon, both from the climatological and public health perspectives, has led to hundreds of UHI studies, mostly conducted on a city-by-city basis. These studies, however, do not provide a complete picture of the UHI for administrative units using a consistent methodology. To address this gap, we characterize clear-sky surface …

Persistent warm Mediterranean surface waters during the Roman period

Nature Abstract Reconstruction of last millennia Sea Surface Temperature (SST) evolution is challenging due to the difficulty retrieving good resolution marine records and to the several uncertainties in the available proxy tools. In this regard, the Roman Period (1 CE to 500 CE) was particularly relevant in the socio-cultural development of the Mediterranean region while its climatic characteristics remain uncertain. Here we present a new SST reconstruction from the Sicily Channel based in Mg/Ca ratios measured on the planktonic foraminifer Globigerinoides ruber. This new record is framed in the context of other previously published Mediterranean SST records from the Alboran …
