Rajendra Pachauri, Chair of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change (IPCC), discusses the geophysical effects of climate change.

He also addresses the vital human dimension, including the social, economic, and equity considerations needed to prepare for future changes. (November 2011)

Despite California's global warming legislation, greenhouse gas emissions continue to rise, potentially leading to a four-degree annual temperature increase. This highlights an urgent environmental challenge.

Randy Hayes, founder of the Rainforest Action Network and described by the Wall Street Journal as “an environmental pit bull,” is addressing this. From Washington D.C., he leads Foundation Earth, a new organization dedicated to rethinking human systems to align with the planet’s life support capabilities.

Christopher Monckton's climate change stance is deemed nonsense. While acknowledging the greenhouse effect, CO2's warming contribution, and human emissions, he asserts: "Yes, there is a greenhouse effect. Yes, CO2 contributes to it. Yes, it causes warming. Yes, we emit CO2. Yes, warming will result. But not a lot."

F. Sherwood Rowland, UCI Bren Research Professor of chemistry and Earth system science, received the 1995 Nobel Prize in chemistry. He was honored for his discovery that chlorofluorocarbons (CFCs) in products like aerosol sprays damage the Earth's protective ozone layer. Although initially controversial, this crucial finding ultimately led to a worldwide ban on CFCs.

Professor Rowland passed away on Saturday, March 10, 2012. This video was produced by Kerrin Piche Serna, University Communications. For more information, visit F. Sherwood Rowland's Wikipedia page or read an Al Jazeera article on ozone.

At TEDxVictoria, photographer Garth Lenz presents striking images of the Alberta Tar Sands mining project. His photos expose the environmental devastation and the beautiful ecosystems under severe threat.

For nearly two decades, Lenz has documented threatened wilderness and indigenous communities, with his work featured in leading publications. His photography of Canada's boreal region has contributed to establishing significant protected areas. A Fellow of the International League Of Conservation Photographers, his major Tar Sands exhibit premiered in Los Angeles in 2011 and toured New York.

This TEDxVictoria talk was filmed on November 19, 2011.

Journalist Naomi Klein, observing the catastrophic aftermath of BP's risky oil pursuit in the Gulf of Mexico, highlighted society's addiction to extreme risk. This pattern extends to new energy sources and financial instruments, often leaving us to manage the resulting messes.

Klein's crucial question emerges: What is our backup plan when these high-stakes ventures fail? Discover more of her insights at http://www.ted.com.

Corporate philanthropy is driving a fundamental business transformation, comparable to the Industrial Revolution. Co-creation and embedded creation are essential to this profound shift.

At the CECP Summit on June 2, Professor Stuart Hart, a leading authority on sustainable development, discussed how companies can move "beyond greening" toward transformational strategic change. He drew insights from his book, Capitalism at the Crossroads: The Unlimited Business Opportunities in Solving the World's Most Difficult Problems, and his article "The Fortune at the Bottom of the Pyramid," co-authored with C.K. Prahalad.

An animation of NASA temperature data from 1880-2011 depicts temperatures relative to a 1951-1980 baseline: red for higher, blue for lower. This visualization underscores a clear warming trend.

NASA scientists report that 2011 was the ninth warmest year globally since 1880.

This finding extends a trend where nine of the ten warmest years in the modern meteorological record have occurred since 2000.
