A new peer-reviewed study refutes Gov. Jerry Brown’s assertion that global warming is behind California’s drought, indicating that climate changeneither makes droughts more likely to occur nor exacerbates them. The study, published this week in the Journal of Climate, shows that the “net effect of climate change” has made California’s agriculture drought “less likely” to happen and that the “current severe impacts of drought on California’s agriculture” has not been exacerbated by long-term climate changes. This is another stinging indictment that Gov. Brown’s belief that global warming is causing California’s drought is bordering on wish fulfillment.
