Pitt Researchers using HPC to turn CO2 into Useful Products

Researchers at the University of Pittsburgh are using XSEDE supercomputing resources to develop new materials that can capture carbon dioxide and turn it into a commercially useful substances. With global climate change resulting from increasing levels of carbon dioxide in the Earth’s atmosphere, the work could lead to a lasting impact on our environment. “The basic idea here is that we are looking to improve the overall energetics of CO2 capture and conversion to some useful material, as opposed to putting it in the ground and just storing it someplace,” said Karl Johnson from the University of Pittsburgh. “But capture and conversion are typically different processes.”

Video: Simulations of Antarctic Meltdown should send chills on Earth Day

In this video, researchers investigate the millennial-scale vulnerability of the Antarctic Ice Sheet (AIS) due solely to the loss of its ice shelves. Starting at the present-day, the AIS evolves for 1000 years, exposing the floating ice shelves to an extreme thinning rate, which results in their complete collapse. The visualizations show the first 500 […]

New Ocean Current Simulations Reflect Climate Change

Researchers are using the Gordon supercomputer at SDSC to paint a new picture of global warming’s impact on the complex processes that drive ocean mixing in the vast eddies swirling off the California coast. “Nearly a fifth of the worldwide ocean productivity is in these zones, and no one has really looked with this level of detail at the climate change implications for these precious marine areas,” said Renault.”

Video: Climate Change, Chaos, and Inexact Computing

In this video from the Perimeter Institute for Theoretical Physics in Ontario, Dr. Tim Palmer from the University of Oxford presents: Climate Change, Chaos, and Inexact Computing. “How well can we predict the climate future? This question is at the heart of Tim Palmer’s research into the links between chaos theory and the science of climate change. Palmer will discuss climate modeling, the emerging concept of inexact supercomputing, and chaos theory.”

How HPC is Helping Solve Climate and Weather Forecasting Challenges

Data accumulation is just one of the challenges facing today weather and climatology researchers and scientists. To understand and predict Earth’s weather and climate, they rely on increasingly complex computer models and simulations based on a constantly growing body of data from around the globe. “It turns out that in today’s HPC technology, the moving of data in and out of the processing units is more demanding in time than the computations performed. To be effective, systems working with weather forecasting and climate modeling require high memory bandwidth and fast interconnect across the system, as well as a robust parallel file system.”

HPC Helps Drive Climate Change Modeling

Because of the complexity involved, the length of the simulation period, and the amounts of data generated, weather prediction and climate modeling on a global basis requires some of the most powerful computers in the world. The models incorporate topography, winds, temperatures, radiation, gas emission, cloud forming, land and sea ice, vegetation, and more. However, although weather prediction and climate modeling make use of a common numerical methods, the items they compute differ.

Video: Big Data Powers Climate Research at BSC

In this video from the Barcelona Supercomputer Center, Big Data is presented as a key challenge for researchers studying global climate change. “Changes in the composition of the atmosphere can affect the habitability of the planet by modifying the air quality and altering long-term climate. Research in this area is devoted to the development, implementation and refinement of global and regional state-of-the-art models for short-term air quality forecasting and long-term climate predictions.”

NASA Charts Sea Level Rise

“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”

Video: Climate Change – Fact, Fiction, and What You Can Do

“Climate change – or as Doug Sisterson, research meteorologist at Argonne National Laboratory, prefers to call it, climate disruption – is probably the greatest challenge we face in modern society, yet many of us don’t fully understand the causes or the consequences. Washington Governor Jay Inslee famously stated: “We’re the first generation to feel the impact of climate change and the last generation that can do something about it.”

HPC Transforms for Researchers of Global Climate Change

“HPC is transforming our everyday lives, as well as our not-so-ordinary ones. From nanomaterials to jet aircrafts, from medical treatments to disaster preparedness, and even the way we wash our clothes; the HPC community has transformed the world in multifaceted ways.”
