the dry, temperate weather that has historically made homelessness in San Diego County relatively tolerable may be a thing of the past. Recent weather in California has been generally both hotter and wetter. Some studies suggest that hotter, much wetter weather may be the new norm for California thanks to global warming.
From an old blog post of mine, written November 2017.
California has about one quarter of America's homeless population, likely due in part to the history of dry, temperate weather in large parts of California. If Cali is going to generally trend hotter and wetter, we need to more urgently than ever find solutions for getting people into permanent housing and keeping them there.
