June 8th, 2020Researchers from NOAA and CU Boulder have devised a breakthrough method for determining emissions of carbon dioxide from fossil fuel combustion. In a paper published in the Proceedings of the National Academy of Sciences, the researchers report the first-ever national estimate of fossil-fuel derived carbon dioxide emissions obtained by observing carbon dioxide and its naturally occurring radioisotope, carbon-14, from air samples collected by the NOAA Global Greenhouse Gas Reference Network. This new method is expected to provide a more accurate look at changes in fossil fuel emissions as the economy begins its recovery amid the COVID-19 pandemic. In addition, the method will be particularly robust at identifying year-to-year emissions trends, allowing governments to independently assess their progress toward meeting the Paris Climate Agreement goals.
June 4th, 2020In recent decades, the oceans have been soaking up greater and greater amounts of carbon dioxide each year. We can’t count on that trend to continue forever, says a new study that includes Nikki Lovenduski.
June 4th, 2020Scientists have been using carbon-dating techniques for years to measure the age of Earth's archaeological treasures. Now they've found a way to use it to identify sources of man-made carbon dioxide emissions in the atmosphere. The research, underway in NOAA laboratories and the University of Colorado, Boulder, since 2003, might help nations and states reduce CO2 emissions from major sources in the fossil fuel and cement industries.
May 28th, 2020Story in The New Republic argues that the situation is bad news for all of us, particularly when it comes to research relevant to our current crises, and quotes Merritt Turetsky.
May 22nd, 2020The first water measurements here were taken in 1903. Long-term monitoring since then tells the tale of an abrupt ecosystem shift. This Science Friday story on Massive Science features Mike Gooseff and Diane McKnight.
May 1st, 2020CU Boulder researchers, led by PhD student Riley Brady and PI Nikki Lovenduski, have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades. The new method, described today in Nature Communications, offers potential to forecast the acceleration or slowdown of ocean acidification.
