Several groups are lauding Monday’s Environmental Protection Agency (EPA) report, which officially concluded that human activity causes greenhouse gases that threaten our health and welfare.

Health Care Without Harm (HCWH), an international coalition of more than 430 organizations in 52 countries, has long maintained that the impacts of climate change would be devastating to the health of world populations through increased famine, heat waves, disruption of the ocean food supply, flooding, disease encroachment, drought, population displacement, war and chronic illness from air pollution.

“As an organization, our goal is to protect public health through reduction of pollution and environmental factors contributing to illness,” say Executive Director Anna Gilmore Hall, RN. “We welcome the EPA statement as a powerful commitment of support to our climate change reduction efforts.”

“With this announcement, the EPA is taking an important step forward,” adds Josh Karliner, the HCWH’s international coordinator. “It is now up to the President to follow through by negotiating a strong and fair agreement in Copenhagen that leads to a binding accord to protect public health from climate change.”

HCWH has placed an advertisement in the New York Times to draw attention to the public health aspects of climate change, and the group has also helped launch an online Prescription for a Healthy Planet initiative. For more information on HCWH’s climate change program, click here.

The National Wildlife Association also hails the EPA decision.

“This action clears the way for serious measures to reduce the pollution that is accelerating global warming, and the timing couldn’t be better,” says Joe Mendelson, the organization’s global warming policy director. “The Obama administration’s action enforces the Clean Air Act and strengthens the President’s hand for the upcoming talks to forge a global deal to fight climate change.

“The announcement follows the recent diplomatic breakthrough with China and India, who both announced their willingness to take action to control pollution if the world acts. For the first time ever, the leaders of the world will gather with offers to act from China and the United States, the world’s two biggest emitters. I am optimistic that the talks will yield a workable plan to protect our children’s future.”
