20. November 2014: Permafrost soil is possible source of abrupt rise in greenhouse gases at end of last ice age
Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have identified a possible source of carbon dioxide (CO2) and other greenhouse gases that were abruptly released to the atmosphere in large quantities around 14,600 years ago. According to this new interpretation, the CO2 – released during the onset of the Bølling/Allerød warm period – presumably had their origin in thawing Arctic permafrost soil and amplified the initial warming through positive feedback. The study now appears online in the journal Nature Communications.
10. November 2014: How variable are ocean temperatures?
The earth’s climate appears to have been more variable over the past 7,000 years than often thought. A new study forthcoming online this week in the U.S. scientific journal “Proceedings of the National Academy of Sciences” (PNAS) shows significant differences between climate archives and climate models.
Around half of the carbon dioxide volume discharged into the atmosphere through exhaust pipes and chimney stacks over the past two hundred years has been absorbed by the oceans - but not without consequence.
With their research and publications scientists from the Alfred Wegener Institute substantially contributed to the IPCC report.We provide interviews, videos and fact sheets on the theme.
