Little evidence linking Global Warming to California drought

The New York Times recently posted a story by Justin Gillis concerning the lack of scientific evidence that Global Warming is causing the California Drought. Gillis writes:

President Obama and his aides cited the state as an example of what could be in store for much of the rest of the country as human-caused climate change intensifies.

But in doing so, they were pushing at the boundaries of scientific knowledge about the relationship between climate change and drought. While a trend of increasing drought that may be linked to global warming has been documented in some regions, including parts of the Mediterranean and in the Southwestern United States, there is no scientific consensus yet that it is a worldwide phenomenon. Nor is there definitive evidence that it is causing California’s problems.

The article concludes that, “It may take years to resolve the scientific uncertainty. But with California’s growing population, the state faces increasing pressure to resolve tensions involved in apportioning its water among city dwellers, farmers, industry and an environment under increasing strain from global warming.”

In other words, the California drought is more likely a result of California politics and poor planning than anything else. To read a real deep dive into the literature wars between so-called experts see Judith Curry’s California Drought in Context.
