BuzzFeed: Climate Change and Wine

Here is a new article in +BuzzFeed about the ways in which vintners are experiencing climate change now, and how climate change could impact winegrapes in the future:

http://www.buzzfeed.com/sandraeallen/how-climate-change-will-end-wine-as-we-know-it

It is a long-form article by Sandra Allen. I have given a lot of interviews about climate change and wine over the past 8 years since our first paper on the topic was published in 2006. In my opinion, this is the most detailed, comprehensive, balanced, and insightful article I have seen on the topic.

Here is a link to a +Stanford University story about one of our peer-reviewed papers on the topic (including a brief video):

Here are links to our peer-reviewed papers on the topic:

NEW RESEARCH: "Anthropogenic warming has increased drought risk in California"

I have a new paper with +Daniel Swain and +Danielle Touma out today in the Proceedings of the National Academy of Sciences. We analyze historical observations, climate model experiments with and without human emissions of greenhouse gases, and climate model experiments assuming continued emissions. From these multiple data sources, we find clear evidence (i.e., high statistical confidence) that human-caused global warming has already increased the risk of the kinds of hot-dry conditions that are responsible for the current severe drought in California.

Here is the "Significance Statement" from the paper:

"California ranks first in the United States in population, economic activity, and agricultural value. The state is currently experiencing a record-setting drought, which has led to acute water shortages, groundwater overdraft, critically low streamflow, and enhanced wildfire risk. Our analyses show that California has historically been more likely to experience drought if precipitation deficits co-occur with warm conditions and that such confluences have increased in recent decades, leading to increases in the fraction of low-precipitation years that yield drought. In addition, we find that human emissions have increased the probability that low-precipitation years are also warm, suggesting that anthropogenic warming is increasing the probability of the co-occurring warm–dry conditions that have created the current California drought."

Here is a link to the peer-reviewed paper, which is available Open Access:
http://www.pnas.org/content/early/2015/02/23/1422385112.abstract

Here is a link to the +Stanford University news story by +Ker Than :

The image (which is from the Stanford news story) shows Lake McClure on February 4, 2015.

Stanford+Connects: Chicago

I am in Chicago for the +Stanford Alumni Stanford+Connects event. It is a beautiful day. There is plenty of ice on the lake, but it is warm and bright if you are standing near the highly reflective bean sculpture in Millennium Park. It's pretty amazing how the whole park warms up around it. It's a great first-hand lesson in surface radiation.

I will be giving a "micro lecture" on climate change in the midwest, followed by a longer seminar on climate risk. The videos from all of the microlectures at the Chicago event (along with past events) will be posted on the Stanford+Connects page here:

Video of Chasing Ice Panel Discussion with Director/Producer Jeff Orlowski

Here is the video of the March 4, 2013, +Stanford University panel discussion of Chasing Ice, a film by Jeff Orlowski that follows photographer James Balog's Extreme Ice Survey. The film includes time-lapse footage of glaciers from around the world, including the calving of Ilulissat Glacier in Greenland. The evening began with a screening of the film, followed by a panel discussion with Director/Producer Jeff Orlowski, Stanford's Terry Root and Michael Wara, and me.

Scientific Field Campaign to Study "Atmospheric Rivers"

There is a scientific field campaign currently underway to take measurements of "atmospheric rivers" over the Pacific Ocean. Atmospheric rivers are concentrated plumes of moisture that bring much of the annual rain and snow to California. The transport of moisture in these rivers from the subtropics to the west coast of North America is often called "The Pineapple Express".

As described in this piece from +Nature Publishing Group  (thanks to +Daniel Swain  for passing it along!) the campaign involves one scientific research vessel and four airplanes:

http://www.nature.com/news/calwater-2015-targets-atmospheric-rivers-off-california-1.16759

The ship is waiting in the Pacific and will be positioned underneath the atmospheric river once it forms, and will sample the river from below. The airplanes will fly into the river and drop sampling instruments ("dropsondes") into the river. This sampling campaign will provide critical new information about the formation and structure of these important atmospheric features.

The image is from +Los Angeles Times , and shows downtown Los Angeles during the atmospheric river event that brought extreme precipitation and flooding to much of California in December 2014:
