Quoted in Mercury Newspaper Article on Sea Level and South SF Bay

Here is a new article in the San Jose Mercury News with some quotes based on our new work on sea level rise and marshes in the southern San Francisco Bay. https://www.mercurynews.com/2018/07/17/how-drawbridge-is-drowning-and-what-it-means-for-our-future/ How Drawbridge is drowning — and what it means for our future Rising seas and sinking muds doom once-vibrant ghost town   The ghost town of Drawbridge is seen from this drone view near San Jose, Calif., on Thursday, June 14, 2018. The town was formerly known as Saline City, and was abandoned decades ago and is now slowly sinking into the marsh. (Jane Tyska/Bay Area News Group)   By Lisa M. Krieger | lkrieger@bayareanewsgroup.com | Bay Area News Group PUBLISHED: July 17, 2018 at 7:00 am | UPDATED: July 17, 2018 at 9:17 am   A century ago, the island town of Drawbridge held 90 homes, hotels and cabins, with hunting so bountiful that dead ducks served as currency at its gambling tables. Now — in a rare act of reverse colonization — civilization is ceding to the elements in this windswept …

Time Magazine Interview on California Fires

I was recently interviewed by Time Magazine on the 2017 California wildfire season.  The combination of high precipitation in the winter promoting much fine fuel growth, the long period since last significant rainfall and the high summer temperatures being experiences in Southern California have produced a dangerous situation.  The main unknown in the equation is the frequency and timing of ignition sources. Let’s hope for the best. Read the Time article here – http://time.com/4838989/california-drought-wildfire-fire-season/

Seal Beach Earthquake Study in the News

Evidence for coseismic subsidence events in a southern California coastal saltmarsh Our lab collaborated on a recent paleoseismology at the Seal Beach Marsh using foraminifera to identify subsidence events related to the Newport-Inglewood fault.  The study was published in Nature.com/Scientific Reports and drew coverage in the Los Angeles Times.  Rob Leeper, formerly USGS and now at UC Riverside was the leader of the work. Much thanks to Dr. Simona Avnaim-Katav in our UCLA lab for the foram work. Take home message – the fault, which transects an important built-up area of Southern California is more active than assumed.

AAG Presidential Column – Creating and Preserving Actionable and Policy-Relevant Geography

Creating and Preserving Actionable and Policy-Relevant Geography news.aag.org/2017/01/creating-and-preserving-actionable-and-policy-relevant-geography/ 1/29/2017 Ensconced in our academic environs, as students or as faculty, we are sometimes accused of being removed and aloof from the issues of the real world and our research regarded as being of purely scholarly interest. Indeed, there are times for many of us that this may be more than a little bit true. I certainly have not been immune to being intrigued by questions with no apparent implications for the practical problems of the here-and-now. However, today, as often has been the case over its long history, the discipline of geography is being called upon — and called out — because of its importance in identifying and addressing problems of the wider world. Three recent items in the news reminded me of the potential role of geographers and geography in addressing the myriad challenges swirling around us at the present time. First, this past week the Prime Minister of the United Kingdom, Theresa May, spoke at a Republican Party meeting in Philadelphia. She then met …
