Study Shows Wildfires Occurring At Higher Elevations

Jul 27, 2015

A new study shows wildfires are increasingly occurring at higher elevations in the Sierra Nevada. As Amy Quinton reports from Sacramento, researchers say climate change and some forest management practices may be driving the change.

Scientists say in the early 20th century, fires rarely burned above 8,000 feet in the Sierra. But in the past three decades, several fires have burned at or above that level every year. The study suggests warming temperatures associated with climate change may be increasing tree density and the amount of fuel.

Scientists Discover What Makes Lake Tahoe Blue

Scientists have long thought that the blueness of Lake Tahoe was due to the lake’s clarity. But as Amy Quinton reports from Sacramento, a new study shows that algae plays an important role.

For the past three years, UC Davis researchers have been measuring the degree of blueness in Lake Tahoe using a NASA research buoy. They compared those results with the lake’s clarity and found something surprising. 

Schadlow: “Clarity and blueness are controlled by very different things.” 

More Wildfires In California, But No 'Mega Fires' In 2015 So Far

There's been a significant increase in the number of wildfires this year in California. But, as Ed Joyce reports from Sacramento, the size of the fires has been relatively small.

Four years of drought and record warm temperatures have created dangerous wildfire conditions in California.

And, it's been a busy year for firefighters.

Berlant: "Already this year we've responded to well over 1200 more fires than we would in an average year for the same time period." 

Climate Scientist: Don't Count On El Nino To End California's Drought

Federal climate scientists say it was a record warm June for California. Capital Public Radio's Ed Joyce reports the hot weather is forecast to continue into the fall.

In this fourth year of drought, NOAA says California had its warmest June in 121 years. The agency said last year was the warmest on record for the state. And this last winter, California had a record-low snowpack in the Sierra.

Famiglietti: "I think that this past winter is representative of what we will very likely be seeing more of in the future."

New "Super Scooper" To Help Firefighters In California

Firefighters in California have another resource to call on to combat wildfires. Ed Joyce reports from Sacramento.

The U.S. Forest Service in Lake Tahoe says the agency’s Bombardier 415 aircraft, nicknamed the “Super Scooper,” will be based out of the South Lake Tahoe Airport this summer.

Forest Service Fire Management Officer Kit Bailey says the aircraft increases the agency’s ability to respond to wildfires.

Marijuana is big business in California. By some estimates pot is actually the state's top cash crop. But with the boom in marijuana cultivation, there is also a significant environmental toll. Mountain tops are being leveled, and streams are being illegally diverted threatening species already stressed by the drought. With the possibility of marijuana legalization looming in 2016, the issue of how to clean up the environmental damage caused by pot production is a big concern. 

By now most people know that almonds use a lot of water, about one gallon per nut. Most growers are relying on groundwater even more this year because their surface water has been cut off because of the drought. But as Valley Public Radio’s Ezra David Romero reports that brings a different problem all together, one that an “Almond Doctor” is trying to solve.

By this time next year, two brand new all electric buses will be rolling down the streets of Porterville. The move away from diesel and hybrid buses is part of efforts to clean up the valley’s air.

For the cost of just under 1-million dollars, Porterville is replacing two of their existing buses with a new generation of clean, emission free all-electric vehicles.

Richard Tree, Porterville’s Transportation Manager, says the decision to go all electric was an easy one.

California Moves To Limit New Lawns

New California homes and businesses may have less grass in the future. The state Water Commission passed a model ordinance Wednesday restricting the amount of turf that can be used in new developments with at least 500 square feet of landscaping. Grass can only make up 25 percent of residential yards. It will essentially be prohibited at non-residential buildings.

There have been previous versions of the model ordinance. But Commissioner Paula Daniels says this version better reflects California’s needs in the drought.

'Wild' Draws Huge Crowds To The Pacific Crest Trail

The Pacific Crest Trail runs two-thousand-six-hundred-fifty miles from Mexico to Canada. Usually a few hundred hardy souls make the trek every year. But, this year about ten times that number are attempting the arduous journey. Lesley McClurg hiked a section of the trail to find out what’s driving its popularity.

The Tuolumne Meadows post office in Yosemite National Park is packed. Ragged hikers wait in a long twisting line outside.
