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.”


California Drought Severity Expected to Increase

December 15, 2017

Los Angeles Times: "California could be hit with significantly more dangerous and more frequent droughts in the near future as High_Pressure_Ridge3.jpgchanges 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.'”

SFGate: "There are 2.4 million dead trees within about 131,000 acres of the national park, according the latest fall count, says park spokesperson Scott Gediman."


Uber's Impact

November 10, 2017

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.


CO2 Level Now Highest in 3 Million Years

November 02, 2017

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."

 


Anarctic Glaciers Shedding Increased Ice

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."
