Scientists project a drier Amazon and wetter Indonesia in the future

Written on April 27, 2018.

UCI-led study examines role of plants, trees in global transfer of rainfall Irvine, Calif., April 27, 2018 – Climate models predict that an increase in greenhouse gases will dry out the Amazon rainforest in the future while causing wetter conditions in the woodlands of Africa and Indonesia. Researchers at the University of California, Irvine and other institutions have identified an unexpected but major factor in this worldwide precipitation shift: the direct response of the forests themselves...

Arctic lakes are releasing relatively young carbon, UCI-led study discovers

Written on January 31, 2018.

Findings paint less dire climate picture, as ancient emissions are more harmful Irvine, Calif., Jan. 31, 2018 – When Arctic permafrost soil thaws, greenhouse gases are released into the atmosphere, but most of the carbon currently escaping from lakes in northern Alaska is relatively young, according to a new study led by researchers at the University of California, Irvine. “This finding is crucial, because much of the biomass stored underground in the Arctic is ancient, dating back to the...

UCI expert among group urging accelerated reduction of greenhouse gas emissions

Written on December 8, 2015.

Article in Nature Climate Change casts doubt on carbon-capture technologies Irvine, Calif., Dec. 8, 2015 – At the beginning of week two of the Paris climate talks, an international group of scientists is calling on the world’s industrial powers to aggressively and immediately reduce greenhouse gas emissions, stressing that overreliance on so-called negative emissions technologies may prove too costly and disruptive to keep Earth from overheating. In an article published today in Nature...

Rich Chinese Export Pollution to Poorer Regions

Written on June 17, 2013.

Limiting pollution in China’s richer provinces has shifted polluting facilities to less prosperous areas with fewer rules Tim Radford, Scientific American Just as rich nations have passed the responsibility for carbon dioxide emissions to the developing nations, so the rich provinces of China have exported the problem to the poorest regions, according to new research. The world’s biggest single emitter of the greenhouse gas – 10 billion tons in 2011 – has undertaken to reduce...

UC Irvine Scientist: Climate Change Policies Not Working Fast Enough

Written on January 10, 2013.

Molly Peterson, Southern California Public Radio A scientist at UC Irvine is calling for greater urgency in the effort to control greenhouse gases. In a study published in Environmental Research Letters, earth systems scientist Steven J. Davis and three co-authors said carbon emissions are growing faster than ever, prompting them to re-think a strategy on reversing climate change. “After eight years of mostly delay, the action now required is significantly greater,” the...

Study: Fixing Climate Change Will Take New Energy Tools

Written on January 8, 2013.

The task is more difficult now than just a few years ago, a new study says, citing the recent surge in global greenhouse-gas emissions. Its co-author proposes eliminating emissions altogether by 2060. Wendy Koch, USA TODAY What will it take to fix climate change? The world will need new technologies that produce energy without emitting greenhouse gases, scientists argue in a study to be published Wednesday. The research looks at a popular 2004 approach put forward by two Princeton scientists...

Donald Blake garners 2013 American Chemical Society award

Written on August 28, 2012.

Tatiana Arizaga, School of Physical Sciences Communications UCI chemistry professor Donald Blake will receive the 2013 National Award for Creative Advances in Environmental Science & Technology from the American Chemical Society. “This award reflects the collaborative efforts of the Rowland-Blake Group to advance the understanding of trace gases in the atmosphere,” Blake said. “I built many of the original analytical tools, and now the group has advanced those tools to...

Wastewater Recycling Actually Increases Greenhouse Gas Emissions

Written on September 29, 2011.

ClickGreen Staff, Click Green Wastewater recycling processes may generate more greenhouse gases than traditional water-treatment processes, a new study has found. Despite this finding, the report suggests there are good reasons to continue keep wastewater recycling among the water-resource tools for urban areas. Author Amy Townsend-Small, assistant professor of geology and geography at the University of Cincinnati, and a team of researchers from the University of California,...

‘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 –...
