Studies indicating historical CO2 levels lag behind temperature have merit, confirms Peter Hildebrand, Director of Earth Science at NASA's Goddard Space Flight Center. Responding to a question on Twitter, Hildebrand explained that in the pre-industrial age, temperature changes drove CO2 levels; a warmer climate caused the biosphere to emit more CO2.

However, in the post-industrial era, this dynamic has reversed. Now, increasing atmospheric CO2 is leading to higher temperatures, indicating a fundamental shift in the physical-biological processes. For more information, visit Ask A Climate Scientist.

In a 16th-century Chamonix mill, Peter and Anati run Le Moulin des Artistes—a ski workshop, art space, and community hub. This venture beautifully illustrates how dedicating one's life to creative expression, through Peter's handmade wooden skis and Anati's art and music, can bring purpose, build lasting community, and even help overcome disaster.

This inspiring story is presented by Patagonia Films, a Yucca Films production. Patagonia's mission is to build the best gear while protecting the planet, a commitment reflected in their use of recycled materials and Worn Wear repair program.

The Arctic's thawing ice threatens to release vast methane hydrate stores, a gas 84 times more potent than CO2. This potential tipping point could dangerously spike atmospheric

The Arctic's thawing ice threatens to release vast methane hydrate stores, a gas 84 times more potent than CO2. This potential tipping point could dangerously spike atmospheric heating.

Peter Fiekowsky and Peter Wadhams propose enhancing natural methane oxidation with Iron Chloride, a method explained in Fiekowsky's book, *Climate Restoration: The Only Future that will Sustain the Human Race*. Funding this planetary "life insurance" is critical.

Cities are significant sources of greenhouse gas emissions, yet they can actively contribute to environmental decarbonization. Peter Droege, an architect and leading expert in sustainable design

Cities are significant sources of greenhouse gas emissions, yet they can actively contribute to environmental decarbonization. Peter Droege, an architect and leading expert in sustainable design and urban planning, offers ten immediate action points for cities. His insights were featured as the introduction to our conference, "The Architecture of Transition," which explored the built environment's pivotal role in shaping sustainable futures through imaginative and precise design.

Drawing from Eastern wisdom and Western science, Peter Russell, with degrees in theoretical physics, experimental psychology, and computer

Drawing from Eastern wisdom and Western science, Peter Russell, with degrees in theoretical physics, experimental psychology, and computer science from Cambridge, applies a sharp, critical mind to self-awakening. He asserts that humanity's next great frontier is inner space – the development of the human mind – addressing profound questions about non-duality, consciousness, and reality.

Russell has authored ten books, including *The Global Brain Awakens* and *From Science to God: A Physicist’s Journey into the Mystery of Consciousness*, synthesizing scientific rationale with intuitive wisdom.

Dr. Peter Victor, Professor and former Dean of Environmental Studies at York

Dr. Peter Victor, Professor and former Dean of Environmental Studies at York University, was interviewed at the International DeGrowth Conference in Barcelona (March 25-29, 2010). He posits that economic growth is not necessary for a good life, and that living well without it is feasible.

The conference discussed not just stabilizing, but actively shrinking the economy—a more challenging but achievable goal requiring significant societal changes. A more in-depth speech by Dr. Victor is available on EarthSayers.tv.
