Overlooked Issues in the U.s. National Climate and Ipcc Assessments

This essay discusses several issues that have been overlooked in the U.S. National and IPCC assessments. These include the effect on the climate system of anthropogenic land-use change, and the biological influence of enhanced concentrations of atmospheric carbon dioxide. Evidence is presented to demonstrate the important role of these human disturbances to the earth’s climate. Several hypothes...

Engineering Critical Assessments of Marine Pipelines with 3D Surface Cracks Considering Weld Mismatch

Offshore pipelines are usually constructed by the use of girth welds, while welds may naturally contain flaws. Currently, fracture assessment procedures such as BS 7910 are based on the stress-based methods and their responses for situations with large plastic strain is suspicious. DNV-OS-F101 with limited modifications proposes a strain-based procedure for such plastic loads. In this paper 3D ...

Do the Uncertainty Ranges in the Ipcc and U.s. National Assessments Account Adequately for Possibly Overlooked Climatic Influences?

In an accompanying editorial essay, Pielke (2002) argues that at least two important forcings have not been treated in the recently published assessments of the Intergovernmental Panel on Climate Change (IPCC, 2001) and the U.S. Global Change Research Program (NAST, 2000, 2001). Pielke opens his essay by suggesting that, if the failure to treat the effects of anthropogenic land cover change and...
