What is in the Air We Breathe?

“What we do in my group is we zoom in on the aerosols.”

Vicki Grassian and her team look at aerosols at a microscopic level to determine their impact on our health and our climate. Aerosols can be mineral dust and sea spray from the ocean or created by human activity or stem from any number of sources. They can travel across the globe impacting people, animals, and the planet in their wake.

Grassian’s work seeks to understand how aerosols and other gases not only affect us but how we might harness them for solar geoengineering.

Beyond Food and Exercise: the Other Factors in the Obesity Epidemic

Everything you come in contact with, every second of every day, makes an impact on your health. It’s known as the exposome. It’s a relatively new concept, first defined in 2005. The exposome includes the food you eat, the beauty products you use, the air you breathe, your friends and family, and everything in between. Studying it, could be the key to understanding the obesity epidemic.

That was the focus of the 12th Annual Sugar, Stress, Environment & Weight Symposium put on by The Consortium for Obesity Assessment, Study, and Treatment at UCSF. Popular opinion would have you believe that obesity is a simple equation of too much food and not enough exercise. But, researchers say the problem is far more complex. In this eye-opening lecture series, you will hear how polluted air has been linked to obesity in children living in California’s Central Valley. You will learn about obesogens – chemicals that disrupt the endocrine system. And, you will understand how stress can create a vicious cycle of weight gain.

The final talk focuses on how you can remove toxins from your personal exposome and the progress being made around the world. New labeling in the food and beauty industries allows you to make smarter decisions. LEED buildings are becoming more common in the United States. And, monitoring systems for exposome pollutants are getting better. There is plenty being done, and plenty you can do, to make an impact.

Can the World Breathe Easy?

UCTV Prime’s series “Lifting the Blanket: The Pursuit of a Climate Change Solution” has been following  the remarkable journey of Scripps Institution of Oceanography’s Veerabhadran Ramanathan, whose scientific curiosity took him from a refrigeration plant in his native country of India to becoming a globally recognized leader in climate change research.

Episodes one and two tracked the progress of his groundbreaking research that identified the significant contribution of CFCs and black carbon soot to global warming. In episode 3, “Can the World Breathe Easy?,” Ramanathan returns to India with an international collaboration to demonstrate that improving cooking methods in the developing world could slow global warming and improve public health along the way.

Watch episode 3 now, or catch up with Ramanthan’s quest to find human-scale solutions to climate change at the series website. Stay tuned February 12 for the fourth and final installment, “Scientific Authority Meets Moral Authority.”

Lifting the Blanket: Pursuit of a Climate Change Solution

Lifting the Blanket: Pursuit of a Climate Change SolutionBeginning his career as an engineer at a refrigeration plant in India, Veerabhadran Ramanathan went on to make one of the most important climate change discoveries when he identified chlorofluorocarbons (CFCs) as even larger contributors to global warming than the previously identified culprit, carbon dioxide.

UCTV Prime’s new four-part series “Lifting the Blanket: Pursuit of a Climate Change Solution,” follows the Scripps Institution of Oceanography scientist’s remarkable path that changed the face of climate change research and has introduced possibilities for human-scale solutions.

The first installment, “The Second Front,” sets the stage for Ramanathan’s incredible journey and it’s available now for free online viewing. Stay tuned February 5 for episode two, “The Dirty Sky.”
