‘Committed’ CO2 emissions jeopardize international climate goals, UCI-led study finds

Written on July 1, 2019.

Existing, planned fossil fuel-burning infrastructure must be retired early, replaced Irvine, Calif., July 1, 2019 – The nations that have signed agreements to stabilize the global mean temperature by 2050 will fail to meet their goals unless existing fossil fuel-burning infrastructure around the world is retired early, according to a study – published today in Nature – by researchers at the University of California, Irvine and other institutions. “We need to reach net-zero carbon dioxide...

Wind and solar power could meet four-fifths of U.S. electricity demand, study finds

Written on February 27, 2018.

UCI, Caltech, Carnegie: Investment in greater storage, transmission capabilities needed Irvine, Calif., Feb. 27, 2018 – The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science. However, meeting 100 percent of electricity demand with only solar and wind energy would require storing...

Economic slump, not natural gas boom, responsible for drop in CO2 emissions

Written on July 21, 2015.

The 11 percent decrease in climate change-causing carbon dioxide emissions in the U.S. between 2007 and 2013 was caused by the global financial recession – not the reduced use of coal, research from the University of California Irvine, the University of Maryland, and the International Institute for Applied Systems Analysis shows. Brian Bell, UC Irvine Irvine, Calif., July 21, 2015 – The 11 percent decrease in climate change-causing carbon dioxide emissions in the U.S. between 2007 and 2013...

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...

China is Outsourcing Carbon Within Its Own Borders, UCI and Others Find

Written on June 10, 2013.

Interior produces 80 percent of CO2 related to goods used in richer coastal areas Janet Wilson, UC Irvine News Just as wealthy nations like the United States are outsourcing their dangerous carbon dioxide emissions to China, rich coastal provinces in that country are outsourcing emissions to poorer provinces in the interior, according to UC Irvine climate change researcher Steve Davis and colleagues. The findings, to be published the week of June 10 in Proceedings of the National...

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...

Major Cuts to Surging CO2 Emissions Are Needed Now, Not Down the Road, Study Finds

Written on January 7, 2013.

Janet Wilson, UC Irvine News Halting climate change will require “a fundamental and disruptive overhaul of the global energy system” to eradicate harmful carbon dioxide emissions, not just stabilize them, according to new findings by UC Irvine and other scientists. In a Jan. 9 paper in Environmental Research Letters, UC Irvine Earth system scientist Steve Davis and others take a fresh look at the popular “wedge” approach to tackling climate change outlined in a 2004 study by Princeton...
