The California drought, now entering its fourth year, is sustained by a number of climate forces. The two most unrelenting factors are heat and dryness. A recent study from Stanford University climate scientist Noah Diffenbaugh links these prominent and ongoing factors to the effects of human-induced global climate change.
Utilizing computer simulations and atmospheric data, the study points to a region of high atmospheric pressure over the Pacific that is depriving California of storms that would otherwise make landfall. The research team argues that greenhouse gases make these conditions more likely, thus essentially attributing the current drought to unchecked gas emissions.
The study has received some criticism for its methods and results. Whether greenhouse gases can be particularly blamed for the California drought remains a matter of contention. However, one undisputed fact remains: California is in desperate need of water.
Greensulate is constructing green roofing sites across the state, not only to relieve some of the effects of the drought, but to temper the underlying meteorological causes. Green roofs retain whatever rainwater does make it to California’s parched landscape. They also contribute to beneficial cloud formations, fighting the drought at its source.
No matter the ultimate cause of the drought, Greensulate roofs are working to alleviate its effects and reverse its chokehold on the California environment.
