Sierra Nevada snowmelt is vital for California. It provides drinking water for 30% of residents, irrigates key San Joaquin Valley crops, and powers hydroelectric plants supplying 15% of the state's electricity.

Scientists Martha Conklin and Tom Harmon (UC Merced) are researching at the Southern Sierra Critical Zone Observatory. They use wireless sensors to accurately measure snowpack and melt, enabling state water managers to make better allocation decisions for this precious resource.

Allan Savory, President and Co-founder of the Savory Institute in Boulder, Colorado, addresses desertification.

He explains that desertification, the turning of land into desert, affects two-thirds of the world's grasslands. This accelerates climate change and destabilizes traditional grazing societies.

Savory has dedicated his life to combating this. His work suggests a surprising method can protect grasslands and restore degraded land.

Addressing plastic pollution requires more than solutions like recycling, bioplastics, or compostable straws. These methods do not tackle the fundamental problem.

The only effective approach is to confront the root cause: halting the production of new plastic. This is the essential step for a lasting solution.

A PBS report, published on December 5, 2012, highlighted a significant plummet in sea production.
