Our 30onClimate webcasts regularly explore current climate change science, policy, and communications issues from the standpoint of outside independent experts in the science and policy arenas. Through the prism of The Yale Forum’s own regular contributors, the webcasts provide regular insights on climate events in the news … or soon likely to be.

Learn about those coming up in 2014 and also our past webcasts here. Join us “live” on the 30onClimate Google+ page OR on the YouTube channel.

“Tracking Carbon In A Warming World”
Wednesday, March 19, 2014
12pm (PT), 3pm (ET)

The “Keeling curve” image of rising atmospheric CO2 concentrations is one of the most iconic in the climate science literature, with a potentially strong message as average concentrations exceed the 400 parts per million threshold.

But a challenging funding environment might soon leave the historic monitoring program in its wake. In that case, how will we track CO2 concentrations in the future? And what would the loss of the Mauna Loa record mean for scientists’ ability to track our changing climate?

Tune in on March 19 with climate scientists Ralph Keeling from the Scripps Institution of Oceanography, La Jolla, Calif., and Britton Stephens from the National Center for Atmospheric Research (NCAR), Boulder, Colo., on these important topics.

RALPH KEELING directs the Scripps CO2 Program at the Scripps Institution of Oceanography (SIO) in La Jolla, CA. He is also a Professor and the Principal Investigator for the Atmospheric Oxygen Research Group at SIO.

Keeling’s research interests include measurements of variations in atmospheric oxygen, recent perturbations to the global carbon cycle, air-sea gas exchange, detection of ocean heat storage and transport using atmospheric gases, and paleoclimate theory. His father, the late Charles David Keeling, was the first person to make high-precision continuous measurements of CO2 levels in the atmosphere from Mauna Loa, Hawaii, resulting in the famous “Keeling Curve” charting CO2′s rise globally. Today, Ralph Keeling leads this program, which faces termination because of budget cuts.

BRITTON STEPHENS is a scientist in the Earth Observing Laboratory of the National Center for Atmospheric Research (NCAR) in Boulder, Co. His research has focused on developing and deploying new instruments for tower-, ship-, and aircraft-based observations of atmospheric O2 and CO2, and on synthesizing data sets and models to elucidate global carbon cycle processes.

Stephens led a synthesis of global airborne CO2 observations with a collection of atmospheric transport models that resulted in a major revision to scientists’ understanding of the latitudinal distribution of carbon sinks. He was a principal investigator on a three-year global airborne survey of greenhouse and related gases that collected an unprecedented data set of more than 90 species from the surface to the tropopause and nearly pole to pole in all seasons. Stephens has maintained a network of mountaintop CO2 instruments in the U.S. Rocky Mountains since 2005 that is being used to investigate regional carbon cycling and disturbance impacts. He also developed and operates a continuous atmospheric O2/CO2 instrument on a ship transiting the Southern Ocean between Chile and Antarctica.

“The Challenges of Climate Change Communication”
Air date: January 15, 2014

Yale Forum regular contributor Bruce Lieberman hosts a discussion on the unique and demanding challenges that communicators must overcome when addressing climate change issues. This second in the ongoing series covers a wide range of issues from the differing, but complementary, perspectives of two of the nations’ leading voices on science communications.

RICHARD ALLEY, Ph.D., a professor in Penn State University’s Department of Geosciences, is a Member of the National Academy of Sciences and the author of award-winning books such as The Two-Mile Time Machine and Earth: The Operators’ Manual, the latter of which is also a PBS documentary. Widely recognized as an outstanding science communicator, Alley is a member of the United Nations’ IPCC.

SUSANNE MOSER, Ph.D., directs her own independent research and consulting firm in Santa Cruz, California. A frequent speaker and author on science communication issues, Moser is a Social Science Research Fellow at the Woods Institute for the Environment at Stanford University and a Research Associate at the University of California-Santa Cruz, Institute for Marine Sciences. She has previously worked at the National Center for Atmospheric Research and with the Union of Concerned Scientists.

“2014: The Year Ahead in Climate Change News”
Air date: December 20, 2013

Hosted by Yale Forum regular contributor Bruce Lieberman, 30onClimate’s premier webcast offers four journalists’ perspectives on major climate issues anticipated — what to watch for and considerations — coming in the 2014 new year. Topics include forthcoming Intergovernmental Panel on Climate Change (IPCC) reports, EPA proposed rulemaking on power plant emissions, NASA satellite launches to collect better climate change data, and the congressionally mandated National Climate Assessment report intended to inform audiences of climate change impacts across the U.S.
