Deep Green: Long-Term Zero-Carbon Power for the 21st Century

Written on November 15, 2011.

Tatiana Arizaga, School of Physical Sciences E-Newsletter On October 18, 2011, Dr. Shaka gave a lecture as part of the 2011-2012 Discover the Physical Sciences Breakfast Lecture Series in which he proposed nuclear technology as the solution to obtaining clean energy. Dr. Shaka believes that continued burning of fossil fuels, with the large influx of carbon dioxide into the atmosphere, could prove to be an enormous and expensive future problem. Furthermore, even if such changes...

‘Green’ spaces may worsen global warming

Written on January 19, 2010.

Turfgrass management can create more greenhouse gas than plants remove from atmosphere, study finds. Jennifer Fitzenberger, University Communications NOTE TO EDITORS: The original version of this story, posted Jan. 19, has been updated here to reflect the correction of a spreadsheet error in the scientific paper regarding carbon dioxide emissions during lawn maintenance. Dispelling the notion that urban “green” spaces help counteract greenhouse gas emissions, new research has found –...

Oceans losing ability to absorb greenhouse gas

Written on January 11, 2010.

Like a dirty filter, the Earth’s oceans are growing less efficient at absorbing vast amounts of carbon dioxide, the major greenhouse gas produced by fossil-fuel burning, reports a study co-authored by Francois Primeau, UC Irvine Earth system science associate professor. Jennifer Fitzenberger, University Communications Like a dirty filter, the Earth’s oceans are growing less efficient at absorbing vast amounts of carbon dioxide, the major greenhouse gas produced by fossil-fuel burning,...

Dinosaurs appeared on Earth about 230 million years ago, when atmospheric oxygen levels were close to half what they are today. Scientists wonder how they survived – for 165 million years – under these varying conditions. UC Irvine biologist James Hicks is finding answers in the alligator, a modern relative of the dinosaur. Jennifer Fitzenberger, University Communications Dinosaurs appeared on Earth about 230 million years ago, when atmospheric oxygen levels were close to half...

South to the pole

UC Irvine chemist Murat Aydin will spend his holiday drilling into the South Pole’s thick ice to collect trapped air that is up to 100 years old. Jennifer Fitzenberger, University Communications UC Irvine chemist Murat Aydin will spend his holiday drilling into the South Pole’s thick ice to collect trapped air that is up to 100 years old. His goal: to analyze trace amounts of gases to see how their levels have changed over time. “It’s almost like studying history – the history...

Drought, deforestation link fuels climate change

Written on December 8, 2008.

In the rainforests of equatorial Asia, the practice of using fire to clear forests and destroy organic soil increases substantially in dry years, releasing huge amounts of climate-warming carbon dioxide into the atmosphere, according to a new international study analyzing six years of weather and fire observations. Jennifer Fitzenberger, University Communications In the rainforests of equatorial Asia, the practice of using fire to clear forests and destroy organic soil increases substantially...

Fungi fight global warming

Written on November 3, 2008.

The fight against climate warming has an unexpected ally: mushrooms growing in the dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions. Jennifer Fitzenberger, University Communications The fight against climate warming has an unexpected ally: mushrooms growing in the dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions. When soil in these forests is warmed, a UC Irvine study found, fungi that feed on dead plant material dry...
