California Air Resources Board: "In California, as in the rest of the world, climate change is contributing to an escalation of serious problems, including raging wildfires, coastal erosion, disruption of water supply, threats to agriculture, spread of insect-borne diseases, and continuing health threats from air pollution."
"The drought that plagued California for years devastated the state’s agricultural and rural communities, leaving some of them with no drinking water at all. In 2015 alone, the drought cost agriculture in the Central Valley an estimated $2.7 billion, and more than 20,000 jobs."
"Last winter, the drought was broken by record-breaking rains, which led to flooding that tore through freeways, threatened rural communities, and isolated coastal areas. This year, California experienced the deadliest wildfires in its history. Climate change is making events like these more frequent, more catastrophic and more costly."

UCLA Institute of the Environment and Sustainability: “Even more fires could be in store for the future as human activity continues to drive climate change,” MacDonald said in October. “We will have a wet year when fire fuels will grow and accumulate, and then we will be hit by very dry conditions, which will dry out soil surfaces and vegetation … and the fuel from the wet year is going to cause fires during dry periods. That is the worst of all possible worlds, and that is what keeps me awake at night.”

Los Angeles Times: "California could be hit with significantly more dangerous and more frequent droughts in the near future as changes in weather patterns triggered by global warming block rainfall from reaching the state, according to new research led by scientists at Lawrence Livermore National Laboratory."
"Using complex new modeling, the scientists have found that rapidly melting Arctic sea ice now threatens to diminish precipitation over California by as much as 15% within 20 to 30 years. Such a change would have profound economic impacts in a state where the most recent drought drained several billion dollars out of the economy, severely stressed infrastructure and highlighted how even the state most proactively confronting global warming is not prepared for its fallout."

“'This is happening very quickly,'” said Noah Diffenbaugh, a climate scientist at Stanford University. “'The change is dramatic, and it is taking place faster than had been projected by climate models.'”

Wall Street Journal: "There is limited information about how these services affect travel patterns, but the Institute of Transportation Studies at the University of California, Davis has documented a 6% reduction in public-transit in major cities that use them."
“'We find that 49% to 61% of ride-hailing trips would have not been made at all, or by walking, biking or transit,' the researchers reported."
Others report that ride-hailing services are vital for getting to and from transit depots like BART.

Guardian: "The concentration of carbon dioxide in the atmosphere increased at record speed last year to hit a level not seen for more than three million years, the UN has warned."
"The last time Earth experienced similar CO2 concentration rates was during the Pliocene era (three to five million years ago), when the sea level was up to 20m higher than now."

New York Times: "Two of the frozen continent’s fastest-moving glaciers are shedding an increasing amount of ice into the Amundsen Sea each year."
"The Pine Island and Thwaites glaciers are among the most critical in the world. They are currently holding back ice that, if melted, would raise the world’s oceans by nearly four feet over centuries, an amount that would put many coastal cities underwater."
