Stormy weather
Flooding isn't new to the Santa Barbara coastline. However, the inundation doesn't always come from the mountains as it did last month in Montecito. Back in 1861-2, a series of large storms washed beach sand more than a quarter mile inland into what today is the Carpinteria Salt Marsh. Although historical accounts document the inland flooding, little has been known about how those storms impacted a now heavily developed California coast. (2018-02-26)

New research indicates likely hydrological implications of rapid global warming
Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events. The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue. (2017-11-20)

Sea level as a metronome of Earth's history
Sedimentary layers contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia. Researchers at UNIGE and UNIL have been working on an analytical method that combines observing deep-water sedimentary strata and measuring in them the isotopic ratio between heavy and light carbon. They have discovered that the cycles that punctuate these sedimentary successions are ascribable to sea level changes. (2017-05-19)

Chemical weathering controls erosion rates in rivers
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the results also may improve scientists' ability to interpret and predict feedbacks between erosion, plate tectonics and Earth's climate. The research, led by The University of Texas at Austin, was published in Nature on April 14, 2016. (2016-04-13)

Alcohol taxes are too low, have not kept up with inflation
State alcohol excise taxes are typically only a few cents per drink and have not kept pace with inflation, according to a new study in the January issue of the Journal of Studies on Alcohol and Drugs. Raising those taxes, according to the authors, represents an opportunity for states to increase revenues while simultaneously improving public health outcomes and costs related to excessive alcohol consumption. (2017-12-13)

The price paid for higher energy is highly dangerous to teeth
Previous scientific research findings have helped to warn consumers that the pH (potential of hydrogen) levels in beverages such as soda could lead to tooth erosion, the breakdown of tooth structure caused by the effect of acid on the teeth that leads to decay. However, the pH level of soft drinks isn't the only factor that causes dental erosion. A beverage's (2008-03-12)

More than 100 years of flooding and erosion in 1 event
Sara Rathburn of Colorado State University and colleagues have developed an integrated sediment, wood, and organic carbon budget for North St. Vrain Creek in the semi-arid Colorado Front Range following an extreme flooding event in September of 2013. Erosion of more than 500,000 cubic meters, or up to ~115-years-worth of weathering products, occurred through landsliding and channel erosion during this event. (2017-03-27)

Multiple sites rich in water ice found on Mars
Erosion on Mars is exposing deposits of water ice, starting at depths as shallow as one to two meters below the surface and extending 100 meters or more. (2018-01-11)

Toothpaste alone does not prevent dental erosion or hypersensitivity

What does global climate have to do with erosion rates?
Geoscientists have been intrigued by a potential link between erosion rates at the Earth's surface and changes in global climate. A new study now calls into question this link. A team of researchers re-examined 30 locations with reported accelerated erosion after the onset of glacial-interglacial cycles a few million years ago. In nearly all of the locations, the proposed link between erosion and global climate could not be confirmed. (2018-07-05)
