Uncertain Science ... Uncertain World

Autor: Henry N. Pollack

Is the world warming due to the Greenhouse Effect? Can nuclear weapon arsenals be relied upon without periodic testing? Is the world running out of oil? What action should be taken against an outbreak of foot-and-mouth or BSE? Why can't scientists pr

Climate records over the last millennium place the twentieth-century warming in a longer historical context. Reconstructions of millennial temperatures show a wide range of variability, raising questions about the reliability of currently available r

Climate Reconstruction from Subsurface Temperatures

Autor: Henry N. Pollack, Shaopeng Huang

Publikováno v: Annual Review of Earth and Planetary Sciences. 28:339-365

Temperature changes at the Earth’s surface propagate downward into the subsurface and impart a thermal signature to the rocks. This signature can be measured in boreholes and then analyzed to reconstruct the surface temperature history over the pas

Inference of ground surface temperature history from borehole temperature data: a comparison of two inverse methods

Autor: Henry N. Pollack, Po Yu Shen, Shaopeng Huang

Publikováno v: Global and Planetary Change. 14:49-57

The problem of inferring ground surface temperature history (GSTH) from borehole temperature-depth data, like virtually every other geophysical inverse problem, is characterized by nonuniqueness because of an inadequate amount of data, and instabilit

Terrestrial heat flow in the Paraná Basin, southern Brazil

Autor: Suzanne Hurter, Henry N. Pollack

Publikováno v: Journal of Geophysical Research: Solid Earth. 101:8659-8671

We present 56 new heat flow values from the intracratonic Parana Basin in southern Brazil. This large basin is filled with up to 5 km of Paleozoic and Mesozoic sedimentary rocks. In the Late Jurassic-Early Cretaceous a great igneous event capped most
