End of the Little Ice Age in the Alps forced by industrial black carbon.

Glaciers in the European Alps began to retreat abruptly from their mid-19th century maximum, marking what appeared to be the end of the Little Ice Age. Alpine temperature and precipitation records suggest that glaciers should instead have continued to grow until circa 1910. Radiative forcing by increasing deposition of industrial black carbon to snow may represent the driver of the abrupt glaci...

Banded corals: changes in oceanic carbon-14 during the little ice age.

Radiocarbon analyses and stable isotope measurements are presented foro recent cores of banded corals from the Florida Straits. These values provide a record of variations in the ratio of carbon-14 to carbon-12 in the dissolved inorganic carbon in the surface waters of the Gulf Stream from A.D. 1642 to 1800. An increase in the carbon-14/carbon-12 ratio of 7 per mil for coral growth during the e...

Constructing recent peat accumulation chronologies using atmospheric fall-out radionuclides

Radionuclide dating is a robust technique for establishing the recent accumulation rate for most peatlands. In this article we review the production of ‘fall-out’ radionuclides and the concepts underlying the dating method. Some inherent problems such as the issues surrounding reduced natural radionuclide deposition, e.g. ‘continentality’, are highlighted. We describe the common radionuclide an...
