by Daiju Narita, Katrin Rehdanz, and Richard S. J. Tol Climatic Change in press, doi:10.1007/s10584-011-0383-3 ABSTRACT: Ocean acidification is increasingly recognized as a major global problem. Yet economic assessments of its effects are currently almost absent. Unlike most other marine organisms, mollusks, which have significant commercial value worldwide, have relatively solid scientific evidence of biological impact…

Stephens Nature Geoscience in press, doi:10.1038/ngeo1375 ABSTRACT: Global climate change results from a small yet persistent imbalance between the amount of sunlight absorbed by Earth and the thermal radiation emitted back to space1….

ABSTRACT: We established a new high-resolution carbonate carbon isotope record of the Albian interval of the Marne a Fucoidi Formation (Central Apennines, Italy), which was deposited on the southern margin of the western Tethys Ocean….
by Gareth S. Jones, Michael Lockwood, and Peter A. Stott Journal of Geophysical Research – Atmospheres in press, doi:10.1029/2011JD017013 ABSTRACT: During the 20th century solar activity increased in magnitude to a so called `grand maximum’. It is probable that this high level of solar activity is at or near its end. It is of great interest…
by Elizabeth Paté-Cornell Climatic Change Volume 33, Number 2, 145-149, DOI: 10.1007/BF00140245 Full text (PDF format) available. ABSTRACT: “The models used in the assessment of the effects of global climate change are based on limited knowledge of the fundamental phenomena, for instance, the role of the clouds and of the oceans (IPCC, 1996). Although a…
Nathan Urban is a Postdoctoral Research Fellow at Princeton’s Woodrow Wilson School of Public and International Affairs. He recently spoke to Planet 3.0 about the topic of climate sensitivity here. Today, he’s graciously agreed to answer some questions about a paper he co-authored that was just published in the journal Science. Q: Thanks for talking…
A contribution to attribution of recent global warming by out-of-sample Granger causality analysis ABSTRACT: The topic of attribution of recent global warming is usually faced by studies performed through global climate models (GCMs). Even simpler econometric models have been applied to this problem, but they led to contrasting results. In this article, we show…
via Lou Grinzo: Just spotted this (http://www.sciencemag.org/content/334/6057/794): Aerosol Indirect Effect on Biogeochemical Cycles and Climate Abstract: The net effect of anthropogenic aerosols on climate is usually considered the sum of the direct radiative effect of anthropogenic aerosols, plus the indirect effect of these aerosols through aerosol-cloud interactions. However, an additional impact of aerosols on a…
Correlation between climate sensitivity and aerosol forcing and its implication for the “climate trap” ABSTRACT: Climate sensitivity and aerosol forcing are dominant uncertain properties of the global climate system. Their estimates based on the inverse approach are interdependent as historical temperature records constrain possible combinations. Nevertheless, many literature projections of future climate are based on…
