PHILADELPHIA — Though churning smokestacks, cud-chewing cows and gasoline-burning vehicles are contributing constantly to greenhouse gas emissions, there are also many processes that do the reverse, pulling molecules like carbon dioxide out of the atmosphere. One of these is chemical weathering, which occurs when rock turns into soil. Carbon dioxide molecules and rain combine to dissolve rock, and the weathering products, including sediment, eventually make their way through waterways to the ocean where some become trapped on the ocean bottom and in coral reefs and seashells.

Penn’s Field Center for Children’s Policy, Practice & Research Works To Change Child Protection Laws
A lot can change in a year.
One year ago, Pennsylvania’s General Assembly established a Task Force on Child Protection to review child-abuse-reporting procedures and laws. In November, the Task Force issued a 400-page report outlining its proposal for revisions to the child abuse-reporting laws in Pennsylvania.
La’Toya Latney’s grandmother has a photo from when Latney was about 5 years old. In it, she is sitting in front of the television, transfixed by a nature program on grizzly bears hunting salmon swimming upstream.
“At that time she said she knew I was going to be a veterinarian, so it’s been a long time coming for me,” says Latney.
