Doctors' lobby supports greenhouse gas regulations

The American Medical Association voted Tuesday to adopt policy supporting the Environmental Protection Agency's authority to regulate greenhouse gas emissions. The AMA is currently holding its semi-annual policymaking meeting in San Diego.

"Changes to our climate pose serious risks to public health," AMA Board Member Edward Langston said in a statement. "This new policy shows the AMA's support for the EPA's authority to protect the health of all Americans by regulating greenhouse gas emissions."

During its meeting, the AMA also voted to support a requirement that student athletes who suffer concussions not be allowed to return to play or practice without a physician's written approval. It also voted to oppose taxes on medical school tuition proposed by several local governments facing budget deficits.
