Hang out with Prof. +Noah Diffenbaugh this Wednesday, April 25 at 11am PDT to discuss his newly published #climatechange research.
 
Announcing Hangouts On Air to discuss new paper this Wednesday April 25, 11am Pacific time (6pm GMT):

We have a new paper out in Nature Climate Change this week. We report that increasing heat waves from climate change cause sharp increases in the year-to-year swings in corn prices, and that a biofuels mandate enhances these effects.

You can read about the paper in the news (including today's New York Times), but I would also like to answer any questions that anyone has directly, without other filters. So, I am going to host a Hangouts On Air at 11am Pacific time (6pm GMT) this Wednesday April 25.

Let me know if you would like to join. I have pasted the Stanford News Service story below, along with a short video.

Stanford Report, April 23, 2012
Climate change may create price volatility in the corn market, say researchers from Stanford and Purdue
America's No. 1 crop could see its prime growing region shift to the Canadian border or its price volatility increase sharply within 30 years. A new Stanford study points to climate change as the cause.

By Rob Jordan

By the time today's elementary schoolers graduate from college, the U.S. corn belt could be forced to move to the Canadian border to escape devastating heat waves brought on by rising global temperatures. If farmers don't move their corn north, the more frequent heat waves could lead to bigger swings in corn prices, or price volatility, which cause spikes in food prices, farmers' incomes and the price livestock farmers and ethanol producers pay for corn.

A study published April 22 in the journal Nature Climate Change shows for the first time climate change's outsized influence on year-to-year swings in corn prices.

Researchers from Stanford and Purdue universities found that climate change's impact on corn price volatility could far outweigh the volatility caused by changing oil prices or government energy policies mandating biofuels production from corn and other crops.

"Frankly, I was surprised that climate had the largest effect of these three influences," said Noah Diffenbaugh, an assistant professor of environmental Earth system science at Stanford's School of Earth Sciences and a fellow at the Stanford Woods Institute for the Environment. "These are substantial changes in price volatility that come from relatively moderate global warming."

The study, based on economic, climatic and agricultural data and computational models, finds that even if climate change stays within the internationally recognized target limit of 3.6 degrees Fahrenheit above pre-industrial levels, the temperature changes could still make damaging heat waves much more common over the U.S. corn belt.

"Severe heat is the big hammer," Diffenbaugh said. "Even one or two degrees of global warming is likely to substantially increase heat waves that lead to low-yield years and more price volatility."

The researchers calculate that when climate change's effects are coupled with federal mandates for biofuel production, corn price volatility could increase sharply over the period from 2020 to 2040. Increasing heat waves will lead to low-yield years, and government-mandated corn sales to ethanol producers limit the market's ability to buffer against low-yield years.

"By limiting the ability of commodity markets to adjust to yield fluctuations, biofuels mandates work in exactly the wrong direction," said Thomas Hertel, a professor of agricultural economics at Purdue University who participated in the study.

"Our results suggest that energy policy decisions are likely to interact with climate change to affect corn price volatility, and that the market effect of a binding biofuel mandate is likely to intensify as the climate warms," Diffenbaugh said.

Diffenbaugh and Hertel also explored the potential of farmers to adapt to the changing climate. They found that, unless corn farmers increase their crops' heat tolerance by as much as 6 degrees Fahrenheit, the areas of high corn production would have to move northward from the current U.S. corn belt to near the Canadian border in order to avoid excessive heat extremes.

"Our goal was to explore the interacting influences of climate, energy markets and energy policy," said Diffenbaugh. "It is clear from our results that those policy decisions could strongly affect the impacts that climate change has on people. And, importantly, we also identify potential opportunities for reducing those impacts through adaptation."

The study was made possible by a grant from the U.S. Department of Energy's Office of Science.

I think that social media is also very important since people spend more and more time online. All the social media channels are important for the "buzz" effect and the benefits are that the word is spreading much faster in online.
Also thanks for sharing this with me to +Swiss Cleaning Services

As Japan rebuilds after last year's devastating earthquake and tsunami, there is a potentially huge demand for the green and information technology being created by Stanford and start-ups across Silicon Valley.
On the anniversary of Japan's deadly quake and tsunami, Stanford experts say alternative energy will drive innovation and help restructure power industry.

"Robots are fun. But one of the reasons we do the event, frankly, is because robots are such a good way to get kids interested in science, technology, engineering and math. And those are very much needed skills in the contemporary economy." -Ryan Calo, director of privacy and robotics at Stanford's Center for Internet and Society

Introduction

Located between San Francisco and San Jose in the heart of Silicon Valley, Stanford University is recognized as one of the world's leading research and teaching institutions.

Leland and Jane Stanford founded the University to "promote the public welfare by exercising an influence on behalf of humanity and civilization." Stanford opened its doors in 1891, and more than a century later, it remains dedicated to finding solutions to the great challenges of the day and to preparing our students for leadership in today's complex world.
