Biospheric Feedback Loops and Rapid Global Climate Change
(National Academy of Sciences, 2010)
A positive feedback loop makes an existing process speed up while a negative feedback loop decreases the impact of an existing process. A source emits carbon dioxide and other greenhouse gases while a sink retain and stores. ...
Sustainability and Waste of Biospheric Resources are Incompatible
(Virginia Tech, 2010)
The quest for sustainable use of the planet is admirable, however the flagrant waste of biospheric resources overrides any efforts towards this goal. Although there is not single solution to achieve immediate sustainability, ...
Incorporating Environmental Variability from Rapid Climate Change into Ecotoxicology Tests
(Society of Environmental Toxicology and Chemistry, 2010)
As climate, similar to most complex, multivariate systems, approaches disequilibrium, variability of critical attributes increases significantly. In order for ecotoxicological testing to be reliable, it should incorporate ...
Eco-ethics and the Biosphere
(Science and Society, 2012)
Sustainable use of the planet is an attractive goal, especially concerning intergenerational ethics. However, a major ecological tipping point has been passed (e.g, melting glaciers) and, in the last three years, evidence ...
Extinction: The Probable Consequence of the Assault on Science and Reason
(Virginia Tech, 2011)
Humans capacity to reason and dependence on nature has been overshadowed by greed and materialism. As a result, humankind has ignored and attacked scientists and the evidence they have found concerning the state of our ...
The Reluctant Warriors: Scientist vs Public Relations Spin Doctors
(Virginia Tech, 2010)
When scientists listen to analyses of existing evidence, they usually can decipher which analysis is supported by a preponderance of evidence, and if no clear evidence emerges they wait until adequate information is ...
The effects of hypolimnetic anoxia on the diel vertical migration of freshwater crustacean zooplankton
(Ecological Society of America, 2018-07)
Lakes and reservoirs worldwide are increasingly experiencing depletion of dissolved oxygen (anoxia) in their bottom waters (the hypolimnion) because of climate change and eutrophication, which is altering the dynamics of ...
Environmental Refugees: Ethical Issues Involving Overpopulation
(National Academy of Sciences, 2010)
Environmental refugees are produced when the human population exceeds the carrying capacity of a particular region and its inhabitants are forced to search for a more hospitable area. Since not much has been done to reduce ...
Slowing Down Biospheric Change
(National Academy of Sciences, 2010)
In the latter part of the 20th century and the beginning of the 21st century, rapid climate change and damage to the biosphere have increased the risks to Homo sapiens. So much harm has already been done to the biosphere ...
Why is Humankind Eliminating its Future
(Virginia Tech, 2011)
Scientific evidence on climate change, including global warming, is more abundant than ever, but politicians and citizens are rejecting or attacking scientists for the evidence they have found. Science is reality based on ...
