More on the junk science reported yesterday out of Stanford University
In the next 30 years, high-value vineyards in Northern California could shrink by 50% because of global warming, according to a new Stanford University study released Thursday.
Applying scenarios from the Intergovernmental Panel on Climate Change, scientists used a climate system computer model and found that Napa and Santa Barbara counties could experience very hot days during the growing season, with temperatures reaching 95 Fahrenheit or higher. The number of hot days will be greater, they say, with about 10 more sweltering days than usual.
As a result, the amount of grape-growing land is projected to decline over the next three decades, the authors wrote.
“There will likely be significant localized temperature changes over the next three decades,” said Noah Diffenbaugh, coauthor of the study and a center fellow at the Woods Institute for the Environment at Stanford. “One of our motivations for the study was to identify the potential impact of those changes, and also to identify the opportunities for growers to take action and adapt.”
This is what the wine growers had to say about similar claims made in March
Napa growers typically thin at least half the crop and the 2010 harvest still ended being one of the three largest of the decade. So the notion that this sunburn problem was wide-spread and devastating as noted at this Treasury vineyard is not true
Secondly, the writer talks about climate change as being the reason for this hot spell. The recent growing season had just three days over 100 degrees compared to a typical growing season having between 10 and 14 days over 100. While we appreciate the writer noting that the Napa Valley Vintners commissioned the most extensive climate research in the industry and writing that the research team has not found rising temperatures outside of some winter to early summer increase of just one degree in overnight temperatures to date, the science proves that climate change that would change grape phenology has not happened. We are not being “deniers,” but simply put, those who enjoy wine cannot be tasting climate change in Napa Valley wines.
