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."

California Supreme Court: "With a 2 degree Celsius increase, disastrous effects become likely, including more extreme and more frequent severe weather, more wildfires, greater frequency of droughts and floods, rapid and higher sea level rise, and increased habitat destruction and extinctions. These environmental effects will undoubtedly lead to serious economic, political, and national security disruptions."

Journal of the American Planning Association: "Scholars have clearly established the conceptual basis for cities to treat curb space as a valuable commodity rather than a free good. They generally conclude that cities should set the right prices for curb parking because the wrong prices do so much harm. Where curb parking is underpriced and overcrowded, drivers cruise the streets hoping to find an open space. This cruising greatly increases traffic congestion: Ten studies conducted in eight cities between 1927 and 2011 found that an average of 34% of cars in congested downtown traffic were cruising for parking."
