Global ocean warming tied to anthropogenic forcing

Time-dependent response of the global ocean clathrate reservoir to climatic and anthropogenic forcing

[1] Buffett and Archer (2004) showed a model of the steady state global ocean clathrate reservoir that reproduces drill data and predicts a global methane inventory of about 5000 Gton C. The model inventory is very sensitive to ocean temperature, with factor-of-two changes in methane inventory in response to temperature changes of 1.5 C. Here we explore the potential time-dependent behavior of ...

Global ocean storage of anthropogenic carbon

The global ocean is a significant sink for anthropogenic carbon (Cant), absorbing roughly a third of human CO2 emitted over the industrial period. Robust estimates of the magnitude and variability of the storage and distribution of Cant in the ocean are therefore important for understanding the human impact on climate. In this synthesis we review observational and model-based estimates of the s...

Global ocean response to orbital forcing in the Holocene

[1] Global upper ocean evolution in the Holocene is studied in two coupled ocean-atmosphere models under orbital forcing conditions at 3, 6, 8, and 11 ka. The annual mean sea surface temperature (SST) changes in the early to mid-Holocene are found to be forced mainly by the annual mean insolation forcing with an overall symmetric response of colder equator (<0.5 C)/warmer high latitudes (<0.4 C...

Isolating the signal of ocean global warming

Anthropogenic global warming: a skeptical point of view.

Anthony R. Lupo, PhD, is Associate Professor of Atmospheric Sciences in the Soil, Environmental, and Atmospheric Sciences Department at the University of Missouri. Contact: lupoa@!missouri.edu Introduction It is a misconception that those who consider themselves skeptical of the human contribution to climate change do not believe that the climate is warming, and further, that a skeptical point ...
