Kammen – Why Democrats and Republicans are Both Right on Climate

ERG professor Dan Kammen authored a guest blog post for the Scientific American on different strategies proposed by the Democratic and Republican Parties to address global warming.

Kammen argues that though these two plans are dramatically different, “the home run strategy for American job creation and industrial leadership is to implement both the Clean Power Plan and the Carbon Dividend Plan.”

ERG PhD Lara Speaks at TEDx Pura Vida 2017

Last week, ERG PhD student José Daniel Lara spoke in Costa Rica at the TEDx Pura Vida 2017 event. Lara’s talk focused on the urgency for Costa Rica to integrate solar energy to power daily life.

He added that the country has the potential to take the lead in renewable energy because. He explained, “In the 20th century, Costa Rica lagged behind on energy issues because we had no mining resources, no coal, no oil, no capital, but now we have it, we have solar energy.”

ERG Professor Emeritus John Holdren on Trump Administration Climate Policy

ERG Professor Emeritus of the Energy & Resources Group John Holdren is featured in the Cape Cod Wave regarding his background before he was appointed senior science advisor to the Obama administration.

The article also covers his stance on President Trump’s plans for climate policy. Less than two weeks after leaving his job at the White House, Holdren commented, “If the Trump administration tries to back away from the Obama agenda of clean energy and reducing greenhouse gas emissions, I assure you there will be strong pushback.”

Arthur Hinton Rosenfeld, a close friend to many in the ERG community, passed away Friday, January 27, 2017. He was 90 years old.

“Art Rosenfeld helped make California the world leader in energy efficiency,” said Gov. Jerry Brown in a statement. “His path-breaking ideas transformed our energy sector from one of massive waste to increasingly elegant efficiency.”

The Berkeley Lab recently released a memorial article covering Art Rosenfeld’s achievements in energy efficiency: Art Rosenfeld Memorial Page

The Daily Cal released an article, covering Art Rosenfeld’s involvement and contributions for the Berkeley community. Read more here.

Kammen Comments on What’s at Stake as Trump Takes Aim at Clean Energy Research

ERG professor Daniel Kammen commented in this MIT Technology Review article on reports that the Trump administration intends to shut down or slash resources for select Department of Energy programs. Many have noted that significant Department of Energy cuts would stand against Trump’s professed focus on job creation, since careers in solar and wind are already among the fastest-growing job sectors in the U.S. economy.

Kammen noted that common sense shows that “if you can leave ideology behind, which I don’t think this administration seems able to do, we know these things create jobs.”

ERG Postdoctoral Researcher Cohen – Water Treatment Methods in Rural China

ERG postdoctoral researcher Alasdair Cohen (Ph.D. ’16) is featured in Thriving Earth Exchange on his collaboration with government health researchers to better understand water treatment methods in rural China. Cohen’s work led to a formal collaboration between UC Berkeley and the Chinese Center for Disease Control and Prevention to work on joint initiatives related to water, health and the environment.

“There is a lot of great research that gets conducted without a readily available channel from research to policy,” said Cohen. “In this case we’re fortunate that if we find that the electric kettles are clearly beneficial, our CCDC colleagues and other government agencies are in a position to implement a program that promotes their use.”

NOAA Was Right, No Pause in Global Warming Says ERG Grad Student Hausfather

A controversial paper published two years ago that concluded there was no detectable slowdown in ocean warming over the previous 15 years — widely known as the “global warming hiatus” — has now been confirmed using independent data in research led by researchers from UC Berkeley and Berkeley Earth, a non-profit research institute focused on climate change.

The 2015 analysis showed that the modern buoys now used to measure ocean temperatures tend to report slightly cooler temperatures than older ship-based systems, even when measuring the same part of the ocean at the same time. As buoy measurements have replaced ship measurements, this had hidden some of the real-world warming.

After correcting for this “cold bias,” researchers with the National Oceanic and Atmospheric Administration concluded in the journal Science that the oceans have actually warmed 0.12 degrees Celsius (0.22 degrees Fahrenheit) per decade since 2000, nearly twice as fast as earlier estimates of 0.07 degrees Celsius per decade. This brought the rate of ocean temperature rise in line with estimates for the previous 30 years, between 1970 and 1999.

Introducing New ERG Faculty Lara Kueppers

The Energy and Resources Group is delighted to announce the arrival of new core faculty member Lara Kueppers. She is an outstanding scholar with a commitment to working across disciplines.

“I am thrilled to be returning to UC Berkeley, with so many opportunities for new collaborations with faculty and students. I’m particularly excited to be joining the inspiring ERG community and look forward to stimulating discussions on all dimensions of sustainability. I’ll be co-teaching ER102 with John [Harte] this spring. I am also looking for new students who are motivated to learn how forests will respond to climate change – particularly in the tropics and in Western North America.”

Dr. Kueppers is an interdisciplinary environmental scientist, whose research focuses on ecological responses and feedbacks to climate change. She uses field experiments and observations, as well as models, to understand climate-ecosystem interactions in forests and agroecosystems. She is deputy director of Next Generation Ecosystem Experiments—Tropics, a long-term, multi-institution project funded by the Department of Energy, to better understand and project tropical forest feedbacks to climate change.

Previously, Dr. Kueppers was a Research Scientist in the Climate and Ecosystem Sciences Division at Berkeley Lab and an Assistant Professor at UC Merced. She holds a PhD from UC Berkeley (ESPM), and MS and BS degrees from Stanford University.

Kammen highlighted in Scientific American

ERG professor Dan Kammen was highlighted in this Scientific American article on the American Geophysical Union’s annual meeting, which featured a talk by California Gov. Jerry Brown on the Trump administration’s impending policy on climate science.

Kammen noted that “opportunities can be seen with some Trump nominees”, who have supported renewable energy development and carbon emission pricing in the past.

New Partnership with Kammen’s RAEL Lab and University of Maryland’s Research for Climate Action

Last week, Daniel Kammen announced that RAEL is supporting and  participating in the launch of the Research for Climate Action global consortium anchored at the University of Maryland.
The RCA provides a means to coordinate researching to share results that will be needed to make the 2 degree path, and ideally the 1.5 High Ambition Coalition goals a reality.
