Science Wednesday: Air Science 40 Seminar

2010 November 3

Each week we write about the science behind environmental protection. Previous Science Wednesdays.

By Maggie Sauerhage

The average person takes 15 breaths a minute. That adds up to 21,600 breaths a day and around 7,884,400 breaths a year. Just thinking about that leaves me breathless.

Recently, I attended a seminar on Capitol Hill titled “Air Quality in a Changing Climate: What the Future Holds for the Air We Breathe,” co-sponsored by EPA and the American Geophysical Union.

At the core of the seminar were presentations by EPA’s Dr. Darrell Winner, and Dr Jonathan Samet, a professor and chair of the Department of Preventative Medicine and Director of the USC Institute for Global Health at the University of Southern California. Usually presentations on the effects of climate change leave me feeling lost and uncertain of the future of our planet.

This was different.

After Dr. Winner explained the climate change penalty on ozone—the relationship between ozone and temperature—he said that research shows that when emissions reductions are enforced, overall air quality improves.

He also mentioned the harmful effects of black carbon emissions. To help combat this problem, the EPA has joined the Global Alliance for Clean Cookstoves to improve air quality and human health around the globe. He finished his lecture by saying that there are great opportunities to slow climate change while improving global public health.

Dr. Samet offered insights on the effects of air pollution and climate change on human health. He shared one particularly interesting slide: two world maps, side-by-side. One showed countries sized according to their contributions to air pollution and climate change. Large contributors, such as the United States, were enlarged. Small contributors, like many in Africa, were shrunken. Next to that map was one illustrating those countries that are most vulnerable to the effects of climate change caused by air pollution.

The countries did not match up at all: the countries that contributed the least to the global pollution problem were identified as some of the most vulnerable!

Both men offered their own suggestions on actions that could both improve the quality of the air we breathe and possibly limit the impacts of climate change. I think that following these suggestions and improving air quality would help us all breathe a little easier.

    Dear Maggie,
    I think, air pollutions from time to time to be on the increase. Look billion people are breathing and also smokes from the forests, transportations, manufactoring town, mountains erruption (tonight Mount Merapi) : predictable and also surpriseble. Impossible we are decreasing it, meanwhile The Universes are most acceleratest than before. Ya, Maggie…: “The Mankinds !!!”. In the future they should be changes : The Bodies and Spirituals—— : Way of Life !!!!

    Diesel emissions are of great influence on pollution!

    The largest contributors to greenhouse gas and smog causing emissions we have are energy related–mostly from diesel engines and diesel and coal fired power plants. An emphasis needs to be placed on alternative forms of energy that are not nearly as polluting. Vehicles could be powered by hydrogen or electric power. Solar power and wind farms combined with electric and natural gas conservation will be important. In the beginning of water conservation, it took time for the idea to take hold with the public and with plumbing and appliance manufacturers. Now nearly all plumbing components and appliances like dishwashers conserve water. The same process needs to happen with electric and gas use , and , with incentives in place, it will. Best wishes, Michael E. Bailey.

    The air pollution problem is a global problem, it’s impossible for a single country to just protect itself, even it has perfect environmental policy. I think it’s good that EPA has joined the Global Alliance for Clean Cookstoves. Only with corporation with other countrys around the world, we, human beings can solve the air pollution problem. As the biggest greenhouse gas emmissioner, the United States should take its responsibility, like really join the Kyoto Protocal, not just signing it as non-bonding.

    The easiest way to install a solar power system is to purchase a solar power kit that includes all of the materials that you need to complete a full system.
