A New U.S. Climate Pledge, but Will the World Follow?

President Biden came into this week’s virtual climate summit with a goal of trying to reassure a skeptical world that the U.S. is back as a leader on the issue.

As the summit heads into its second and final day, Biden has appeared to have accomplished that. But the talks also revealed the limits of his ability to build support for the more aggressive action that experts say is needed.

Leaders of 40 countries said they were serious about combating climate change, but only a few matched their rhetoric with new commitments for reducing emissions, and those who did said little about how they’d meet those targets.

The president announced at the outset that he was doubling the United States’ initial commitment to reduce planet-warming emissions under the 2015 Paris climate agreement, signaling a break from the U.S. abandonment of that pact under former President Trump. Japan and Canada said they would strengthen their goals as well.

Fulfilling the U.S. commitment will require sweeping changes in how Americans power their vehicles, homes and factories, but administration officials said little about how the country would get there. The new goal is slightly more aggressive than California’s, according to two independent analyses.

However, China and India — Nos. 1 and 3, respectively, in highest carbon emissions — offered nothing new. Neither country announced stronger plans to reduce emissions in the near term, to end their reliance on coal-generated electricity or, in China’s case, to stop financing the construction of coal-fired plants abroad.

Proof of Vaccination Will Be Required

The University of California and California State University said they will require COVID-19 vaccinations for all students, faculty and staff on campus properties this fall once the Food and Drug Administration gives formal approval to the vaccines and supplies are sufficiently available.

The directive is the largest of its kind in U.S. higher education, affecting more than 1 million members of the two public university systems. More than five dozen colleges nationwide have already announced they will require vaccination for enrollment this fall, including Yale, Princeton, Columbia and, in Claremont, Pomona and Claremont McKenna.

But the UC and Cal State systems have not yet taken that step because of questions over the legality of requiring vaccines before they have been formally approved by the FDA. And as with other mandatory shots for measles, mumps, rubella and chickenpox, the COVID-19 directive would allow for students or employees to seek an exemption based on medical or religious grounds.

Backlash for a Judge’s Order on Homelessness

A federal judge’s order calling on L.A. to offer shelter or housing to every homeless person on skid row is setting off growing alarm that his decision could upend years of homeless policy in the city, stalling construction of dozens of housing projects.

This week, Judge David O. Carter threw a major wrench into L.A.’s plan for addressing homelessness, demanding that Mayor Eric Garcetti take roughly $1 billion he had been planning to spend on the crisis and put it into an escrow account. At the same time, he issued a blistering critique of the Proposition HHH program, the 2016 bond measure whose projects have been beset by delays and rising costs.

Some HHH developers, who already have projects under construction or are months away from breaking ground, said they fear Carter intends to raid HHH funding and direct the money elsewhere. The order is also drawing criticism from city leaders who say it lacks a basic grasp of how municipal budgets work.

FROM THE ARCHIVES

What goes into making an Oscar? In 1970, The Times delved into the process. At the time, they were made at a Los Angeles company called Dodge Trophies. The prized statuettes took weeks to create and involved layers of copper, nickel and gold before they were ready for their closeups. Ultimately, 40 were made that year.

But don’t make the mistake of thinking you can sell them. In a 2016 story, the Academy of Motion Picture Arts and Sciences told The Times there are strict rules to prevent the awards from becoming “items of commerce.” They’ll pursue legal action for selling both real and fake ones. But if you’re really committed to a sale? The Academy will buy it back for a flat $10.
