Scientists throw light on mysterious ice age temperature jumpsCardiff, UK (SPX) Jun 22, 2017 Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15C within just a few decades during the ice age periods. In a new study, the researchers show that rising levels of CO2 could have reached a tipping point during these glacial periods, triggering a series of chain events that caused temperatures to rise abruptly. The findings, which have been published in the journal Nature Geoscience, add to mounting evidence sugge ... read more |
