More scientists and others fighting climate change and its effects from 'PBS NewsHour'

I closed 'PBS NewsHour's Tipping Points examines scientists fighting climate change and its effects by writing "PBS NewsHour has more, but I'm stopping here to eat lunch and grade papers." Here are those clips, beginning with Carbon credit program pays small landowners to keep forests standing.

Markets to offset carbon emissions are now worth about $2 billion annually, and supporters say they're a key tool to address climate change.

That's a wrap for today's brief educational entry. Stay tuned for more Emmy Awards coverage tomorrow.
