Temperature rises could be higher than predicted
Climate change could cause bigger swings in temperature rise than previously thought, scientists at NUI Galway believe. Researchers believe temperature rises during "abrupt" climate events some 125,000 years ago may have been 4C higher than had previously been thought, suggesting that the impact of climate change in the future may be greater than expected.
Dr Audrey Morley, from NUI Galway, said the study - published in the 'Geochemistry, Geophysics, Geosystems' journal - was important, because understanding and predictions of future climate events relied on past examples from Earth's climate history.
"Robust and quantitative methods to deduce the magnitude of abrupt climate events from the geologic record are therefore essential," she said.
