Last winter’s drought-busting wet weather was a boon for reservoirs and parched landscapes, but not so much for some invasive species in San Francisco Bay, according to a long-term study by Tiburon-based researchers. All that fresh water that poured into the bay was bad news for certain invaders, which have turned up in droves in recent decades from around the world, often in ships’ ballast water.
In 1991, Mt. Pinatubo in the Philippines erupted and blanketed the stratosphere with sulfur dioxide particles. The earth cooled 0.7 to 0.9 degrees for two years. It’s theoretically possible for humankind to do something similar as a way to counteract climate change. And Rep. Jerry McNerney, D-Stockton, wants scientists to explore the possibilities.
After combing through a decade’s worth of Pennsylvania birth records, researchers have found that pregnant women living within two-thirds of a mile of a hydraulic fracturing well were 25% more likely to give birth to a worryingly small infant than were women who lived at least 10 miles outside that zone during pregnancy.
The Sierra Nevada mountains grew nearly an inch taller during the recent drought and shrank by half an inch when water and snow returned to the area, according to new research from NASA’s Jet Propulsion Laboratory in La Cañada Flintridge. Researchers used 1,300 GPS stations throughout the mountain range to closely observe how its elevation changed during the drought.
Taxpayers may not realize it, but they foot the bill as their city or county complies with new state regulations to improve the health of local streams and waterways. Nicole Beck, 49, a UC Santa Cruz alum with a doctorate in aquatic chemistry, is marrying science and software to help city and county staff get information to make better decisions on where to focus their limited resources.
Severe wildfire seasons like the one that has devastated California this fall may occur more frequently because of climate change, scientists say. … The reason is an expected impact of climate change in California: increasing year-to-year variability in temperature and precipitation that will create greater contrast between drought years and wet years.
When it comes to filling jobs dealing with complex science, environment and health issues, the Trump administration is nominating people with fewer science academic credentials than their Obama predecessors. … The AP analyzed 65 Senate-confirmable positions that deal with science and environment, many of which haven’t been filled yet after 10 months.
As our climate changes, human creativity has been turning to solutions to problems ranging from restoring water supplies to rebuilding failing ecosystems. In interviews, six scientists discussed their efforts to slow or even reverse changes brought by warming.
California could be hit with significantly more dangerous and more frequent droughts in the near future as changes in weather patterns triggered by global warming block rainfall from reaching the state, according to new research led by scientists at Lawrence Livermore National Laboratory.
On the heels of northern California’s wettest year on record — with nearly 90 inches of rain — a team of water agencies and weather researchers is installing a new radar system to upgrade flood prediction in the San Francisco Bay Area. For many, it can’t come soon enough.
The last great hope of avoiding catastrophic climate change may lie in a substance so commonplace that we typically ignore it or else walk all over it: the soil beneath our feet. … Now scientists are documenting how sequestering carbon in soil can produce a double dividend: It reduces climate change by extracting carbon from the atmosphere, and it restores the health of degraded soil and increases agricultural yields.
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.”
