An Hsi Report: The Impact Of Animal Agriculture On Global Warming And Climate Change, Humane Society International

HSI REPORTS

The farm animal production sector is the single largest anthropogenic user of land, contributing to soil degradation, dwindling water supplies, and air pollution. The breadth of this sector‘s impacts has been largely underappreciated. Meat, egg, and milk production are not narrowly focused on the rearing and slaughtering of farm animals. The animal agriculture sector also encompasses feed grain production which requires substantial water, energy, and chemical inputs, as well as energy expenditures to transport feed, live animals, and animal products. All of this comes at a substantial cost to the environment.

One of animal agriculture‘s greatest environmental impacts is its …

Proxy-Based Reconstructions Of Hemispheric And Global Surface Temperature Variations Over The Past Two Millennia, Michael E. Mann, Scott Rutherford

Arts & Sciences Faculty Publications

Following the suggestions of a recent National Research Council report [NRC (National Research Council) (2006) Surface Temperature Reconstructions for the Last 2,000 Years (Natl Acad Press, Washington, DC).], we reconstruct surface temperature at hemispheric and global scale for much of the last 2,000 years using a greatly expanded set of proxy data for decadal-to-centennial climate changes, recently updated instrumental data, and complementary methods that have been thoroughly tested and validated with model simulation experiments. Our results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context. Recent warmth appears anomalous for at least …

Greening The Campus: Contemporary Student Environmental Activism, Ashley Dawson

Publications and Research

In November 1992, the Union of Concerned Scientists (UCS) issued a report entitled "World Scientists' Warning to Humanity." Written by UCS Chair Henry Kendall and signed by 1,700 of the worlds leading scientists, including the majority of Nobel laureates in the sciences, the report's admonition was conveyed in the strongest terms.

Is Climate Change The 21st Century’S Most Urgent Environmental Problem?, Indur M. Goklany

Center for Applied Economics

Some have argued that the Kyoto Protocol and other schemes for immediately mitigating greenhouse gas (GHG) emissions are justified because human-induced global warming is, in the words of the 42nd U.S. President, William J. Clinton, “the overriding environmental challenge” facing the globe today.1 Another argument, advanced by those who are more cautious and perhaps less prone to hyperbole, is that the impacts of global warming – on top of myriad other global public health and environmental threats – may prove to be the proverbial “straw that broke the camel’s back.” They suggest that climate change will overwhelm human and natural …
