Understanding why nights are getting warmer faster than days

Observations from the last fifty years have shown that the nights have been warming much faster than the days. Analysis of the causes of this more rapid warming at night shows that this is likely to continue in the coming decades.

IMOS: Isfjorden Marine Observatory Svalbard

IMOS will support long-term synergistic cooperation between Russian and Norwegian scientists working in Svalbard by establishing a joint marine plankton observatory in Isfjorden.

Isfjorden is the largest fjord system in Svalbard, located in the dynamic transition zone between warm Atlantic and colder Arctic climate regimes. We will expand the existing time series on seasonal hydrography and plankton dynamics in ice-free Adventfjorden (since 2009) and seasonal ice covered Billefjorden (since 2001) with an observatory located in the mouth of Isfjorden close to Barentsburg and an observatory in the deep Karlskronadjupet, close to Longyearbyen.

Investigating the possible causes for the recent warming hiatus

The IPCC stated in their latest assessment report that the global warming hiatus was attributable in roughly equal measure to natural variability and reduced trends in external forcing. A detailed study involving over 2000 years of model simulations has demonstrated that according to the Norwegian Earth System Model, there is no evidence that forcings errors play a significant role in explaining the hiatus. These results has been addressed in two papers lead by Nansen Center scientists Drs. Stephen Outten and Peter Thorne recently published in Journal of Geophysical Research.

PARADIGM: Prediction And RegionAl DowscalInG Models

Establish a framework for generating, evaluating and improving regional predictions of climate on seasonal-to-decadal time scale, by combining regionally focused analyses of predictive potential, and dynamical downscaling of climate predictions

The regional effects of climate change can be heavily modulated by internal variability on time scales of seasons to decades. This climate variability may either mitigate or exacerbate the impacts of global warming and therefore has profound implications for mitigation and adaptation planning. The CMIP experiments provide global climate scenarios in response to external forcing, but they are not initialized in agreement with the observed state of the climate. Over the past decade, initialized climate predictions have been developed and are included in the 5th IPCC assessment report.
