Journal ArticleDOI
Beyond Global Warming: Ecology and Global Change
TL;DR: There are three major causes of global environmental change: increasing carbon dioxide in the atmosphere, alterations in the biogeochemistry of the global nitrogen cycle, and ongoing land use/land cover change as mentioned in this paper.

Carbon Dioxide Exchange Between Atmosphere and Ocean and the Question of an Increase of Atmospheric CO2 during the Past Decades
Roger Revelle,Hans E. Suess +1 more
TL;DR: In this article, the average lifetime of a CO 2 molecule in the atmosphere before it is dissolved into the sea is of the order of 10 years, which means that most of the CO 2 released by artificial fuel combustion since the beginning of the industrial revolution must have been absorbed by the oceans and that the increase of atmospheric CO 2 from this cause is at present small but may become significant during future decades if industrial fuel combustion continues to rise exponentially.

Radiocarbon calibration curve spanning 0 to 50,000 years BP based on paired 230 Th/ 234 U/ 238 U and 14 C dates on pristine corals
Richard G. Fairbanks,Richard G. Fairbanks,Richard A. Mortlock,Tzu-Chien Chiu,Tzu-Chien Chiu,Li Cao,Li Cao,Alexey Kaplan,Thomas P. Guilderson,Thomas P. Guilderson,Todd W. Fairbanks,Arthur L. Bloom,Pieter Meiert Grootes,Marie-Josée Nadeau +13 more
TL;DR: In this article, the authors presented high precision paired 230 Th/ 234 U/ 238 U and 14 C age determinations on pristine coral samples that enable them to extend the radiocarbon calibration curve from 12,000 to 50,000 years before present.
Journal ArticleDOI
Unusual activity of the Sun during recent decades compared to the previous 11,000 years
TL;DR: A reconstruction of the sunspot number covering the past 11,400 years is reported, based on dendrochronologically dated radiocarbon concentrations, and it is pointed out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades.

Journal ArticleDOI
The geochemistry of the stable carbon isotopes
TL;DR: A survey of the variation of the ratio C13/C12 in nature can be found in this paper, where Urey and his co-workers used two complete feed systems with magnetic switching to determine small differences in isotope ratios between samples and a standard gas.
Journal ArticleDOI
Carbon 13 in Plants and the Relationships between Carbon 13 and Carbon 14 Variations in Nature
TL;DR: In this article, the mechanism of isotopic fractionation in plants is discussed, in an attempt to evaluate the relative effects of the local environment and of the activities of the plants themselves.
Journal ArticleDOI
World-Wide Distribution of Natural Radiocarbon
E. C. Anderson,Willard F. Libby +1 more
TL;DR: The natural radiocarbon content of biological materials collected from locations widely scattered over the earth's surface have shown no evidence of the latitudinal variation which would be expected were the turnover time for the biosphere comparable with the mean life of radioccarbon as discussed by the authors.
