CU-Boulder prof speaks on mass media role in climate change skepticism | Bioscience Technology Online
Boykoff, an assistant professor of environmental studies, presented his research today at the annual meeting of the American Association for the Advancement of Science in San Diego. He spoke during a panel discussion titled "Understanding Climate Change Skepticism: Its Sources and Strategies."

Boykoff's segment was titled "Exaggerating Denialism: Media Representations of Outlier Views on Climate Change" and discussed prominent pitfalls.

Speakers Stephen Schneider from Stanford University; Naomi Oreskes from the University of California, San Diego; William Freudenburg from the University of California, Santa Barbara; and Riley Dunlap from Oklahoma State University joined Boykoff on the panel.
the Foresight Institute » New Freitas paper: Diamond Trees
Robert A. Freitas Jr., “Diamond Trees (Tropostats): A Molecular Manufacturing Based System for Compositional Atmospheric Homeostasis,” IMM Report 43, 10 February 2010
Abstract. The future technology of molecular manufacturing will enable long-term sequestration
of atmospheric carbon in solid diamond products, along with sequestration of lesser masses of
numerous air pollutants, yielding pristine air worldwide ~30 years after implementation. A
global population of 143 x 10^9 20-kg “diamond trees” or tropostats, generating 28.6 TW of
thermally non-polluting solar power and covering ~0.1% of the planetary surface, can create and
actively maintain compositional atmospheric homeostasis as a key step toward achieving
comprehensive human control of Earth’s climate.

The Hockey Schtick: "Cliff Notes" on the last 2 Million Years of Climate Change
2 million years ago: Cycles in Earth’s relation to the sun produce alternating Ice Ages (lasting 90,000 to 100,000 years) and “intergalacials” (lasting 10,000 to 20,000 years). The onset of the glacial period is often slow but ends abruptly at the transition to the warm period. The average global temperature changes 5-7 degrees C during this transition but may rise as much as 10-15 degrees C over a time span of less than 75 years at higher latitudes.
Cow farts and Dr Pachauri | CLIMATEGATE
Conclusion? Dr. Pachauri had to say something shocking that only affected Westerners. He couldn’t suggest banning rice production as a source of methane, or that would outrage developing countries. Similarly he couldn’t suggest culling ruminants as India has larger herds than anyone, and killing them is a religious taboo. That left eating meat as his perfect target, which ignores the fact that eating meat doesn’t produce methane at all. If producing meat for food is inefficient then surely maintaining the world’s larget herd of cattle that is never eaten is even more inefficient.
