Acrostics from a Cross Scientist: Kammen Has a Message for Trump

Daniel Kammen, UC Berkeley professor of Energy and Director of the Renewable and Appropriate Energy Lab, has publicly resigned his role as State Department science envoy. The U.S. Science Envoy Program, an outreach initiative started by the Obama administration, sends top scientists abroad to promote the country’s commitment to science and technology as tools for diplomacy; envoys typically serve for one year.

What Does the Calving of that Huge Iceberg Mean for the Planet?

The calving of an iceberg the size of Delaware from the Antarctica Peninsula’s Larsen C ice shelf made a lot of waves, raising concerns that it might directly contribute to sea level rise or portend a sudden acceleration in the melting of the continent’s gigantic ice cap. But the event pointed to neither scenario, says UC Berkeley Professor of Ocean, Earth, and Climate Science Kurt Cuffey.

What Cal Experts Are Saying About the Paris Climate Accord Exit

Today, standing amongst the vibrant natural beauty of the White House Rose Garden, Trump said America will be “getting out” of the Paris Accord, an agreement among 195 countries to gradually reduce climate change to protect nature. Feeling the heat of this decision, UC Berkeley professors take to the Internet to explain what “getting out” of the agreement will get us into.

How Do Journalists Cover a President Who Calls Them the Enemy?

In January 2016, David Fahrenthold, a political reporter at The Washington Post, took note as Donald Trump promised to donate $6 million to help veterans, including $1 million of his own, during a televised fundraiser. As he followed the presidential candidate to rallies across the country, Fahrenthold saw him hand over about $1 million in oversized checks from his foundation. What happened to the rest of the money? he wondered. Fahrenthold expected it would take him a couple of days to find out.

Living for the City

The remote locations of tech company campuses have provided certain benefits for employees and a creepy setting for every techpocalypse novel and film EVER, but they also have their drawbacks, as a recent UC Berkeley study concludes. Read more about Earth Week Reading Roundup »

Greening the Planet: The Fertilizer Effect of CO2 Slows Warming

A new study led by UC Berkeley Lab researcher Trevor Keenan suggests that increased plant growth is slowing the accumulation of carbon dioxide in the atmosphere, a finding that could help explain the mystery of why the uptick in CO2 concentrations has leveled off since 2002, even as emissions have increased. “We believed one of the planet’s main carbon sinks had unexpectedly strengthened,” Keenan explained in a Lab press release. “The question was: which one?” Read more about Greening the Planet: The Fertilizer Effect of CO2 Slows Warming »

Notes from Understory: A Berkeley Biologist Gauges the Health of the Redwoods from the Ferns on the Forest Floor.

Emily Burns was driving north from the Bay Area one day, idly woolgathering, when it hit her.

“Western sword ferns,” she recalls thinking. “They’re twice as big in the northern end of their range as in the southern end. And it struck me that it had to be due to water availability. The fact that it’s wetter in Redwood National Park in Humboldt County than, say, Lime Kiln Creek on the Big Sur coast translates as larger ferns in the north. It all seems obvious now, but there was nothing in the literature on it.” Read more about Notes from Understory: A Berkeley Biologist Gauges the Health of the Redwoods from the Ferns on the Forest Floor. »

Strip It and Stash It: Climate Scientists Focus on Extracting the Carbon Already in Our Air

For decades, most of the strategizing about how to slow down climate change has focused on cutting emissions of carbon dioxide and other greenhouse gases, mainly by shifting away from fossil fuels. Other proposals range from reducing meat consumption (cattle belch massive quantities of methane, a potent greenhouse gas) to curtailment of chlorofluorocarbons (compounds that both retain heat and destroy atmospheric ozone) in refrigerants and aerosols.  Read more about Strip It and Stash It: Climate Scientists Focus on Extracting the Carbon Already in Our Air »
