    In a recent paper in the journal Nature Climate Change, Meehl, Teng and Arblaster (2014) examine individual global climate model runs from models participating in the fifth phase of the Coupled Model Intercomparison Project (CMIP5) to see if any runs replicated the observed early-2000s hiatus in surface temperature warming. They found that those individual model runs that have Interdecadal Pacific Oscillation (IPO) values that matched with observed values successfully simulate the early 2000s hiatus. Using data available in the mid-1990s, they also apply a recently-developed climate prediction technique that uses modern global climate models (GCM), initialized with observations, to make so-called “decadal climate predictions” and find that both the negative phase of the IPO and the surface temperature hiatus could be predicted with this method, using only data that was available prior to the hiatus.

    In a recent article published in the journal Nature, Kossin et al. (2014) use satellite data and reanalysis products to see if there has been a shift in the latitudes at which tropical storms reach their maximum intensity over the 1982-2012 period. The authors find that, globally, the latitudes of maximum intensity have shifted poleward, 53 kilometres per decade in the Northern Hemisphere and 62 kilometres per decade in the Southern Hemisphere. This trend of poleward migration is evident in all ocean basins, except the North Indian Ocean basin, in homogenized satellite and so-called “best track” data. Kossin and colleagues note that this migration is apparently linked to: (1) the absolute difference between wind speeds in the upper and lower troposphere and (2) potential intensity. These have both experienced changes that can be linked to the expansion of the tropics, which is thought to be due, in part, to anthropogenic causes.

    To improve local understanding and manage the impacts of atmospheric river events, the B.C. Ministry of Environment commissioned work to summarize the current state of knowledge pertaining to BC on this topic and conduct a multi-agency qualitative risk assessment.
    In April 2013, scientists and researchers gathered in Victoria, B.C. to review and summarize the current state of knowledge on atmospheric rivers. As a result of their efforts, the Pacific Climate Impacts Consortium and Pinna Sustainability produced this "Atmospheric River State of Knowledge Report."

    A recent meta-analysis published in the journal Nature Climate Change, by Challinor et al. (2014) examines 1,722 crop model simulations, run using global climate model output under several emissions scenarios, to evaluate the potential effects of climate change and adaptation on crop yield. The authors find that, without adaptation, projected corn, rice and wheat production is reduced when areas experience 2.0 °C or more of local warming, with losses greater in the second half of the century due to larger changes in climate. Crop-level adaptations are projected to be able to increase yields by an average of 7-15% when compared to similar scenarios that do not utilize adaptation. Projections indicate that adaptation may be more successful for wheat and rice than for corn. Though less data is available on yield variability, Challinor et al. find that it is likely to increase.

    This Science Brief covers two papers by in the journal Atmosphere-Ocean, on future ocean conditions for British Columbia’s continental shelf. Using an ocean circulation model for the shelf, the authors find that surface temperatures may increase by 0.5 to 2.0 °C, seasonal surface salinity may drop by up to 2 PSS in some areas, and that Haida Eddies will strengthen, as will the Vancouver Island Coastal Current and freshwater discharges into coastal waters.
