On a day when the Union of Concerned Scientists makes headlines with a study on Emissions pathways, climate change, and impacts on California that predicts harm to the California wine industry, the Hoover Institute's Henry Miller points out a much more direct threat to the wine industry there: execessive regulation.

An infestation of Pierce's disease threatens severe damage to the state's vines:

"Counting only grapes, the disease now threatens a crop production value of $3.2 billion and associated economic activity in excess of $33 billion. Other crop and ornamental plant resources such as almonds ($897 million) and susceptible species of citrus ($1.07 billion), stone fruits ($905 million), and shade trees are also at risk."

The best answer is to introduce genetic resistance by gene-splicing. But, no:

The EPA discriminates against gene-spliced varieties, by regulating even more stringently than chemical pesticides any plant that has been modified with gene-splicing techniques to enhance its pest- or disease-resistance. This policy, which has been attacked repeatedly by the scientific community as unscientific and irrational, has badly damaged agricultural research and development. It flouts the widespread scientific consensus that gene-splicing is more precise, circumscribed and predictable than other techniques. New gene-spliced varieties can not only increase yields, make better use of existing farmland and conserve water, but -- especially for grains and nuts -- are a potential boon to public health, because the harvest will have lower levels of contamination with toxic fungi and insect parts than conventional varieties. Moreover, by reducing the need for spraying crops with chemical pesticides, they are environmentally and occupationally friendly.

Agbiotech's potential is proven. A decade ago, an epidemic of papaya ringspot virus had virtually destroyed Hawaii's $64 million a year papaya crop, but by 1998 biotech researchers provided virus-resistant varieties that have preserved the industry.

Yet, the EPA holds gene-spliced plants to an inappropriate, extraordinary standard, requiring hugely expensive testing as though these plants were highly toxic chemicals. In effect, these policies impose a hugely punitive tax on a superior, and badly needed, technology.

If we want to save the California wine industry, rescinding those EPA regulations would be a good start. It'd be easier than trying to change the weather.
