Peter Thornton

Peter Thornton, deputy director of the Oak Ridge National Laboratory’s Climate Change Science Institute and group leader for the Terrestrial Systems Modeling Group in ORNL’s Environmental Sciences Division, will describe the current best understanding of climate change on Thursday, February 22 at 7 p.m., a press release said. The public is invited to attend this free program.

Thornton’s presentation will describe evidence regarding historical and modern climate changes, and projections of future climate based on Earth system models, the press release said. His current research involves the development, evaluation, and application of Earth system models for future climate change prediction. His areas of expertise include the interaction of water, energy, carbon, and nutrients within land ecosystems, the interactions of vegetation communities with the atmosphere, and weather observations over land, the release said. (See a brief ORNL summary here.)

The presentation, co-sponsored by Tennessee Citizens for Wilderness Planning, Climate Coalition Lobby-Knoxville, and the Citizens Climate Coalition at Oak Ridge Unitarian Universalist Church, will be in the Social Room at the Oak Ridge Civic Center.

The U.S. Senate Appropriations Committee has rejected a Trump administration proposal to close a National Oceanic and Atmospheric Administration laboratory that has a division in Oak Ridge.

The budget submitted to Congress by President Donald Trump on Tuesday, May 23, had proposed closing NOAA’s Air Resources Laboratory. That air research laboratory has a field office in Oak Ridge, the Atmospheric Turbulence and Diffusion Division, or ATDD, on South Illinois Avenue.

But an appropriations bill approved by the Senate Appropriations Committee in a 30-1 vote on Thursday explicitly rejected the proposed elimination of the Air Resources Laboratory, which is part of NOAA’s Office of Oceanic and Atmospheric Research. (See page 40 here.)

The Senate committee recommended providing at least as much funding for the Air Resources Laboratory in fiscal year 2018 as in fiscal year 2017. Fiscal year 2018 starts October 1.

The bill approved by the Senate Appropriations Committee on Thursday is the Fiscal Year 2018 Commerce, Justice, Science, and Related Agencies Appropriations Act. It’s not clear when the legislation will be considered by the full Senate. [Read more…]

Katharine Hayhoe, a nationally-recognized climate scientist and evangelical Christian, will give a talk in Oak Ridge on Tuesday, May 16, a press release said.

The free talk is hosted by the League of Women Voters of Oak Ridge and the Climate Change Science Institute at Oak Ridge National Laboratory. Seats are limited.

Hayhoe’s presentation is titled “Climate for Change.” It’s scheduled from 7 to 9 p.m. Tuesday, May 16, at the Pollard Technology Conference Center at 210 Badger Avenue in Oak Ridge.

Hayhoe is both a distinguished climate scientist and an evangelical Christian, the press release said. An atmospheric scientist, her research focuses on developing and applying high-resolution climate projections to understand what climate change means for society.

Hayhoe has been named one of Time Magazine’s 100 most influential people and one of Foreign Policy’s 100 leading global thinkers, and she was recently named one of Fortune’s world’s greatest leaders, the press release said. She is a professor in the Department of Political Science and Director of the Climate Science Center at Texas Tech University. [Read more…]

If successful, ORNL process could play role in fighting climate change

In October, Oak Ridge National Laboratory announced that scientists had developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol.

This month, Oak Ridge Today asked if the process using the very small catalysts could be used on a large scale to convert carbon dioxide in the atmosphere into ethanol, and if that might be used to combat climate change.

Here is the response from researcher Adam Rondinone, lead author of a team’s study published in ChemistrySelect:

“If we are successful, then yes, this process will take us a little bit closer to the goal of mitigating climate change. But many other technologies and changes will also be needed, because of the scale of the problem. Also, this technology is more focused on what to do with CO2 (carbon dioxide) once it has been captured. While it could feasibly be coupled to a capture mechanism for extracting CO2 from the air, it will more likely be used to intercept and recycle emissions from point sources like power plants. Ultimately, it will just be one solution out of many that we will need to implement in order to prevent serious climate changes.” [Read more…]

The University of Tennessee Arboretum Society will present a program on global warming and climate change on Thursday in Oak Ridge.

The program, titled “It’s all in the Timing: Impacts of Global Warming on Ecosystems and Phenology,” is scheduled from 6-8 p.m. Thursday, January 19, in the City Room at Roane State Community College.

It will be presented by Joanne Logan, who is an associate professor at the University of Tennessee and a renowned expert on the subject, a press release said. Logan is an associate professor in the UT Department of Biosystems Engineering and Soil Science. She has studied applied and agricultural climatology for 30 years, and she directs the undergraduate program in environmental and soil siences, the press release said. [Read more…]

The University of Oklahoma and Oak Ridge Associated Universities were recently awarded $8.4 million over three years from the National Oceanic and Atmospheric Administration to conduct weather and climate change monitoring research. The funding provides OU with the opportunity to expand its Cooperative Institute for Mesoscale Meteorological Studies’ research capabilities through a partnership with NOAA’s ORAU-managed Atmospheric Turbulence and Diffusion Division, or ATDD, program, a press release said.

“CIMMS is one of OU’s treasures as it has played a significant role in advancing our understanding of the atmosphere as well as provided valuable technologies and tools for operational forecasters,” said Kelvin Droegemeier, OU vice president for research. “This new award will build upon these historical strengths to address some of today’s most compelling challenges in weather and climate.”

The award will help further OU’s key research in areas such as boundary layer characterization, which is the atmospheric layer closest to Earth’s surface, and climate observations and analyses. This research will directly support NOAA’s goal to improve prediction of severe weather near the earth’s surface and will provide funding for a research position at the ATDD location in Oak Ridge.

Climate and energy scientists at Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise.

“For the first time, we were able to apply data at a high enough resolution to be relevant,” said ORNL’s Melissa Allen, co-author of “Impacts of Climate Change on Sub-regional Electricity Demand and Distribution in the Southern United States,” published in Nature Energy.

Allen and her team developed new algorithms that combine ORNL’s unique infrastructure and population datasets with high-resolution climate simulations run on the lab’s Titan supercomputer. The integrated approach identifies substations at the neighborhood level and determines their ability to handle additional demand based on predicted changes in climate and population.

The new, high-resolution capability can explore the interconnections in complex systems such as critical infrastructure and weather and determine potential pathways to adapt to future global change, a press release said. [Read more…]
