Understanding climate for the benefit of society. BCCR is a collaboration on climate research between the University of Bergen, NORCE, The Norwegian Institute of Marine Research and Nansen Environmental and Remote Sensing Center.
For the first time, scientist discovered that the large up-and-downs in oxygen isotopes of the mid Oligocene were primarily driven by large temperature changes in the abyssal ocean and not, as previously assumed, to enormous changes in ice volume in Antarctica. 3/3

Oligocene deep ocean oxygen isotope variations primarily driven by temperature - Nature Geoscience
Large benthic oxygen isotope fluctuations in the Oligocene Southern Ocean primarily represent deep water temperature changes, suggesting the Antarctic ice sheet volume was relatively stable, according to a clumped isotope record.

⚠️ However, one problem with the method is that it is not always easy to disentangle from the signal the contribution of temperature and that of ice volume. 2/3

Mapping the Demand, Development, and Delivery of Climate Services in the Greater Horn of Africa
The fragmented and hasty development and delivery of climate services across the Greater Horn of Africa since 2009, largely detached from actual demand, has significant implications for their usabili...
