Postdoctoral scholar Yujie He's research featured in Chemistry World

Carbon dioxide is vital for photosynthesis, so it is generally assumed that in a world with more carbon dioxide plants will grow faster and when they die more carbon will locked away in soil. A crucial question, however, is how quickly soils can respond to long term changes in atmospheric carbon dioxide. Climate models today use soil models based principally on laboratory studies, but terrestrial ecosystem scientist Yujie He of the University of California, Irvine, US, says these neglect some mechanisms that may prevent the carbon content of soil increasing rapidly.

Scientists from the University of California, Irvine (UCI) found that models used by the UN’s Intergovernmental Panel on Climate Change (IPCC) assume a much faster cycling of carbon through soils than is actually the case. Data taken from 157 soil samples taken from around the world show the average age of soil carbon is more than six times older than previously thought.

How does the drought affect California's wildfires?

"What makes it dry is a lack of rain, of course, and the opposite of rain, [which is] lots of evapotranspiration, and that leads to excessive drying that's really desiccating those timbers – the timber and grasses – and turning them into a real tinder box," said Jay Famiglietti, professor of Earth system science and civil and environmental engineering at the University of California, Irvine.

Eric Rignot, a climate scientist at NASA and the University of California, Irvine and a co-author on Hansen's study, said their new research doesn't necessarily change the worst-case scenario on sea-level rise, it just makes it much more pressing to think about and discuss, especially among world leaders. In particular, says Rignot, the new research shows a two-degree Celsius rise in global temperature – the previously agreed upon "safe" level of climate change – "would be a catastrophe for sea-level rise."

Associate Researcher Murat Aydin featured on ABC News for ice core research

Ice cores have led scientists to significant conclusions about climate, including that CO2 levels in the atmosphere today are higher than at any other time recorded in the ice. "The only reason we can make that statement is because we have the ice core air archived," said Murat Aydin, a researcher at the University of California, Irvine.
