An increase in the flux of nitrogen from the Mississippi river during the latter half of the
twentieth century has caused eutrophication and chronic seasonal hypoxia in the shallow …

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 …

Quantifying groundwater fluxes to and from deep aquifers or shallow sediment is a critical
task faced by researchers and practitioners from many environmental science disciplines …

For an accurate assessment of the relative roles of natural variability and anthropogenic
influence in the Earth's climate, reconstructions of past temperatures from the pre-industrial …

Geothermics is an area of geophysics that studies the thermal state and history of the interior
of the Earth. Solar heat penetrates only into the topmost layers of the Earth's crust. Diurnal …

In response to a request from Congress, Surface Temperature Reconstructions for the Last
2,000 Years assesses the state of scientific efforts to reconstruct surface temperature records …

A series of type curves is presented for evaluating vertical groundwater fluxes under the
condition of a linear increase in surface temperature. The depths of minimum groundwater …

The rates of many processes that control rock breakdown into transportable particles are
dependent upon rock temperature. In particular, frost-cracking depends largely upon the …

This paper is an attempt to show that global warming and climate change are real, and are
greatly affecting the biosphere. Evidences suggesting that the increasing concentration of …

Climate for the 21st century is expected to be considerably different from the present and
recent past. Industrialization growth combined with the increasing CO2 concentration in the …
