Enormous wildfires spark scramble to improve fire models
(Nature) Jeff Tollefson, Aug. 31
…“Something is definitely different, and it raises questions about how much we really know,” says Max Moritz, a fire scientist at the University of California, Santa Barbara.
… The problem, Moritz says, is that most of the fire models in use today are based on data from the past two or three decades. But it seems that fire behaviour might be shifting in response to climate faster than anybody expected, and that makes it increasingly problematic to extrapolate from past trends, he adds.

UC: Tariffs could cost fruit, nut industries over $3 billion
(Farm Press) Aug. 15
A new report released by the University of California Agriculture and Natural Resources' Agricultural Issues Center estimates the higher tariffs could cost major U.S. fruit and nut industries $2.64 billion per year in exports to countries imposing the higher tariffs, and as much as $3.34 billion by reducing prices in alternative markets.
Evacuation priorities: Save people first, then...
Climate change is only partly fueling the catastrophic fires in California. Fire scientists also lay blame on the tendency of land use planners to allow the construction of houses and businesses in areas where wildfires are a natural part of the ecosystem.
Last week Gov. Brown forecast a rise in the number, intensity, and cost of fires, warning of “the new normal that we will have to face," reported Martin Kuz in the Christian Science Monitor.
Wildfire experts say its not a new normal but has become normal because lawmakers have avoided prodding local officials, developers, and residents toward an approach to...
Low-lying morning clouds in Southern California coastal areas form the predictable "June Gloom" in early summer - at least, they used to. The combination of urbanization and a warming climate are driving up summer temperatures, reducing cloud cover and increasing the risk of bigger and more intense wildfires, reported Julie Cohen of UC Santa Barbara's The Current.
A new study out of UC Riverside projects an increase in rain and snow in California due to climate change, reported Matt Smith on Seeker.com. Anthropogenic impacts on climate are expected to produce a chronic El Niño-like weather pattern off the Pacific coast of the U.S., leading to about 12 percent more rain and snow by 2100.
The study used a newer computer model and relied on other models that have a better record of simulating precipitation and the effects of an El Niño on the state. El Niño, the cyclical warming of the Pacific Ocean near Earth's equator, typically produces warmer...
