North Tahoe Middle School took their science class outdoors last month to study sugar pines, the largest species of pine tree. Sugar pines, well known for their exceptionally large cones, are being decimated in the Lake Tahoe area by bark beetles and a parasitic fungus known as White Pine Blister Rust. As part of their ecology course, the seventh graders worked with Headwaters Science Institute to design and conduct original experiments to learn more about why sugar pines are dying off and in what conditions they grow best.
Few places will feel the plight of climate change as hard as the Arctic. Our upper pole is warming faster than any other region on Earth, a trend that may be tied to erratic weather patterns across the northern hemisphere. Those are two takeaways from the 2018 Arctic Report Card, which was released Tuesday at the American Geophysical Union conference in Washington, D.C.
Among the up-is-down, night-is-day practices of the Trump administration, one of the most dangerous and disturbing is its habit of turning America’s leading science agencies into hives of anti-science policymaking. A new report lays out how this has produced a “monumental disaster” for science at the Department of the Interior.
The Department of Water Resources (DWR) presented Dr. Bin Guan with the 2018 Climate Science Service Award for his tool that identifies atmospheric rivers in weather models. The work supports experimental forecasts of these large storms earlier than current models. … DWR staff presented the 2018 award to Dr. Guan on December 5 at a DWR/Water Education Foundation workshop in Irvine. The topic of the workshop was improving sub-seasonal to seasonal precipitation forecasting.
A rare fire tornado that raged during this summer’s deadly Carr Fire in Northern California was created by a combination of scorching weather, erratic winds and an ice-topped cloud that towered miles into the atmosphere, according to a study announced Wednesday.
Dam operators are planning to store nearly 4 billion extra gallons of water this winter in Lake Mendocino, the reservoir near Ukiah that plays a critical role in providing water for residents, ranchers and fish along the upper Russian River and to communities in Sonoma and Marin counties.
The U.S. Geological Survey joins its many partners in other federal agencies, at universities, and in state and local governments in recognizing the importance of the Water Resources Research Act (WRRA) of 1964.
Signed into law 50 years ago by President Lyndon B. Johnson on July 17, 1964, the WRRA established a Water Resources Research Institute in each state and Puerto Rico.
A new global geologic map of Mars –the most thorough representation of the “Red Planet’s” surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration.
Seasonal carbon dioxide frost, not liquid water, is the main driver in forming gullies on Mars today, according to a recent U.S. Geological Survey study that relied on NASA’s Mars Reconnaissance Orbiter’s (MRO) repeated high-resolution observations.
[Jim] Walker and construction crews building a new 220-foot-high dam at Calaveras Reservoir in the remote canyons east of Milpitas have been digging up a prehistoric treasure trove: the teeth of an extinct hippopotamus-like creature called a Desmostylus, clams, barnacles and the giant teeth from a 40-foot-long shark — and what could turn out to be an entire whale skeleton.
“During the last year, whole oceans worth of water have been found in the [Earth's] mantle, hundreds of kilometers below the crust. And a paper in today’s [June 12] issue of Science traces water’s influence all the way down to an important boundary inside the Earth, the top of the lower mantle.”
“California’s drought is imperiling tricolored blackbirds, large trees and native fish, with some of the affected species already on the state’s endangered list and others likely headed there because of rapidly declining numbers, scientists say.”
“On her way to visit the Kearney Agricultural Research and Extension Center in Parlier on Monday, University of California President Janet Napolitano got a bird’s eye view of California cropland and rivers dry from the drought — a sight she hopes the universities can help fix through continued research and outreach.”
“By crunching data from the Central Valley, eBird can generate maps showing where virtually every species congregates in the remaining wetlands. … The BirdReturns program, financed by the Nature Conservancy, then pays rice farmers in the birds’ flight path to keep their fields flooded with irrigation water from the Sacramento River as migrating flocks arrive.
