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/ Advertisements

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.

International Press Coverage on Drought Study

Wow! Our drought study – MacDonald, G. M., Moser, K.A., Bloom, A. M., Potito, A.P., Porinchu, D.F., Holmquist, J.R., Hughes, J. and Kremenetski, K.V. 2016. Prolonged California aridity linked to climate warming and Pacific sea surface temperature. Nature.Com/Sci. Rep. 6, 33325;  http://www.nature.com/articles/srep33325 – garnered international press coverage in print, online, television and radio. It was really quite something.  The headlines and stories were a bit more sensational than our rather conservative wording in the actual article.  That being said – it is good idea at this time to consider that California and the West is likely to be more arid in the coming decades, from higher temperatures and evaporation rates if nothing else, and we should some serious thinking and planning. Hopefully this media attention will help get people thinking about these challenges in California and the Southwest.  The thing that worries me is that although we might be able to develop engineering and conservation strategies for the water applied to our farms and cities, we will not be able to irrigate the vast areas …

New Study on Drought by MacDonald Lab

I was the lead author on a new study of California drought based on using lake sediment records from the Sierra Nevada to look at how past climate warming has impacted the Pacific Ocean and California hydroclimate. This work took many years and was a real team effort between the MacDonald Lab’s graduate students and post-docs and Professor Katrina Moser and her team from the University of Western Ontario in Canada. Just like the stock market, past performance does not predict the future, but it can provide insights into what might occur with continued warming.   The article was published in Nature.com/Scientific Reports and is freely available to read and download at the Nature.com site – MacDonald, G.
