But as Lauren Sommer reports, not everyone is happy about it.

When Teaching Climate Gets Controversial

In the wake of mid-term elections, most pundits agree that a national climate change policy is farther from reach. That puts science museums and aquariums around the state in a bind. Several are currently showing exhibits on climate change in an effort to educate the public on this complicated topic. But as Marjorie Sun reports, these institutions have to walk a fine line through a thicket of sensitive issues.

Lichen Point to Pollution

Air pollution may seem like an urban problem, but it’s becoming an increasing concern in California’s national parks. Pollution from cars and trucks blows into the Sierra Nevada mountains, where it can have a dramatic impact on the ecosystem. In Yosemite National Park, researchers are trying to gauge that impact and they’re using an unexpected tool: a fungus called lichen.

Sewage Spills Increasing

How much sewage makes its way into our water? Plenty. Statewide, it's likely that last year's record number, 20 million gallons of raw sewage dumped in California waterways, is going to be broken this year. Decrepit pipes, lack of money and the growing severity of storms could all add up to a disaster of septic proportions.
