It's going to be a dry, ugly summer. We're only in May and fires have begun erupting around the state. Our reservoirs aren't close to capacity and they won't get help from the remaining snowpack.
Climate change has created a "new normal" that is far from easy to predict. Scientists tell us to prepare for extremes. By this, they mean extreme events far beyond what is "normal" in a state known for its disastrous wildfires, droughts, floods and mudslides.
Earlier this year, the U.S. Global Change Research Program released a draft of its Climate Assessment Report. It noted that the Southwest, including California, has heated up markedly in recent decades.
"The period since 1950 has been hotter than any comparable period in at least 600 years," the report stated, citing more than 10 studies.
Climate models -- not absolute proof, but the best tools available for forecasting the future -- show that annual average temperatures in the Southwest are projected to rise 2 to 6 degrees Fahrenheit by 2041-2070 even if global emissions of greenhouse gases are substantially reduced.
The Climate Assessment Report warns that the Southwest should prepare for decreased snowpack and stream flows, meaning reduced water for cities, agriculture and fisheries.
It predicts serious impacts on high-value crops, stronger floods and more extreme high tides. And it warns that, with 90 percent of the Southwest's population living in urban areas, heat waves will claim an ever-higher toll.
California has been a leader in reducing greenhouse gases through cleaner cars, energy efficiency, conservation and a law requiring a reduction in emissions. But adaptation has to be an equal part of the strategy.
Overall, and especially on the local and regional level, public officials aren't taking seriously the need to prepare their communities for the kind of extreme events that are inevitable with a changing climate.
These extremes -- and the responses to them -- vary depending on where Californians live.
In the Central Valley, authorities must prepare communities for flooding evacuations and protracted heat waves that are particularly brutal, especially for the elderly and infirm.
In coastal areas, sea level rise is projected to increase, and flooding and erosion already are occurring in places where houses were built too close to the water or too close to cliffs.
In Southern California and the foothills, wildfires are the primary threat, and the unrestrained construction of suburban homes in wildfire zones complicates the task of first responders.
California has developed a "climate change adaptation strategy" that is thoughtful and comprehensive, including a tool called "Cal-Adapt" that allows local officials to better understand projected impacts to their communities.
Local leaders need to read this report and take the threats seriously. To adapt to a changing climate, cities and counties will have to be proactive in planning for more extreme floods, droughts and fires, even if it means changing their general plans that were developed under the "old normal."
